Imaging tools help radiologists diagnose lung cancer, save lives
Biomedical Imaging

RIT scientists develop imaging software to compare and measure nodules

Jun. 12, 2014
Susan Gawlowicz


Associate professor Nathan Cahill ’97, ’00 (applied mathematics; industrial and applied mathematics), standing, is improving biomedical image computing, the focus of his Ph.D. research. He and imaging science Ph.D. student Kfir Ben Zikri ’11 (electrical engineering) are developing algorithms for a longitudinal study of lung nodules in CT scans. (A. Sue Weisler)

Medical-imaging software under development at Rochester Institute of Technology could someday give radiologists a tool for measuring the growth of nodules in patients at risk of lung cancer, the leading cause of cancer deaths in the United States, according to the Center for Disease Control and Prevention.

Nathan Cahill, an associate professor in RIT’s School of Mathematical Sciences, is creating algorithms to quantify the growth of lung nodules imaged on Computed Tomography (CT) scans. The two-year, longitudinal study, funded by the National Institutes of Health, compares existing scans of individual patients. The algorithms will analyze medical images, measuring changes in nodules to identify small cancers or, if stable, obviate unnecessary, often risky biopsies.

Simple factors can complicate the comparison of CT scans, creating extraneous information in medical images, introducing artifacts and possible errors in diagnosis.

“It’s not an apples-to-apples problem with reliable correspondence between two images,” Cahill said.

Discrepancies between scans of a single patient can result from differences in position and inhalation during imaging. A 10-pound weight gain between CT scans can also affect how surrounding organs push against the lungs and stretch or compress the nodules.

“Having even 1 or 2 millimeters of difference could throw off the estimates of the volumes of the nodules because the size of the nodules might be 5 millimeters or so,” Cahill said. “The goal of this project is to develop an algorithm that tries to compensate for all those potential background factors.”

Dr. David Fetzer, a radiologist at the University of Pittsburgh Medical Center and a member of the collaboration, suggested the clinical problem. Fetzer, an alumnus from the RIT Chester F. Carlson Center for Imaging Science, had worked as an undergraduate with Maria Helguera, professor in the center, and a member of Cahill’s team.

“Modern CT imaging devices produce hundreds and sometimes thousands of images,” Fetzer said. “If a patient is being followed for an abnormality, such as a lung nodule, a radiologist must compare these images visually, mentally compensating for differences such as patient position. Slight changes in technique between two CT scans may simulate tumor growth, for instance.”

Radiologists compute the doubling time of a nodule, or the range of time it takes for the size of the nodule to increase twofold. A mass that doubles in less than 30 days is growing fast and could be an infection, Cahill said. “If it takes more than one and a half years to double, it’s growing slowly and is probably benign. If it’s anywhere between that—one month and 1.5 years—then, it could be malignant and you have to do further testing and do biopsy.”

Cahill and Kfir Ben Zikri, a Ph.D. student in the Center for Imaging Science, are registering, or aligning, backgrounds to create a common frame of reference between sets of images. The process geometrically transforms one three-dimensional image into another and compensates for background information that blurs edges of nodules, even when underlying diseases like emphysema or fibrosis make intensities in the background brighter.

“Then we can estimate the volumes, which will allow us to more accurately estimate the doubling time and have a better chance to determine if it’s a malignant growth or benign,” Cahill said.

The technology will be part of the free software libraries offered by Kitware, a North Carolina-based, open-source software company that specializes in medical image analyses. Cahill and Ben Zikri work closely with scientists at Kitware and professor Marc Niethammer at the University of North Carolina at Chapel Hill.

Fetzer is selecting 30 CT scans of patients treated for lung cancer at the University of Pittsburgh Medical Center. The images are scrubbed of patient-identifying information and sent to Cahill and Ben Zikri. Fetzer will clinically verify the algorithmic results.

“With today’s technology we have the ability to create three-dimensional datasets, volumes of image data that can be manipulated and analyzed in non-visual ways,” Fetzer said. “With techniques such as this we may be able to compensate for background changes and, hopefully, more accurately show growth, assess aggressiveness or prove stability of a nodule. This accurate assessment could dramatically affect patient care, decrease cost and the number unnecessary procedures, and improve outcomes through earlier cancer detection.”

My Masters thesis focused on Medical Image Processing and Enhancement, so I was often searching for universities that are reputable in the field of Imaging - which brought me to the Center for Imaging Science at RIT. The multidisciplinary nature of CIS was an interesting feature that I really wanted to experience. Being exposed to different applications, from medical to hyperspectral imaging, from electron microcopy where we are looking for an object of a size of 10 nanometers, to astronomical imaging where we are looking for objects thousands of kilometers big, is an awesome experience! I’m currently working as a graduate research assistant within my research field of interest: Virtual Reality. Using this powerful tool and combining it with motion capture technology plus a built in eye-tracker, we are studying how human perception systems interact with the world. When I came here my upper-class friends used to tell me, “Hey, you’ll meet all the nicest and most helpful people in CIS.” As far as my experience goes, I couldn't agree more; we’re actually a “family” here.

I’ve always had an interest in “seeing” the world in more than just the red, green, blue that our eyes provide. It was only a matter of time before I found the only school in the country that offers a degree in Imaging Science. Imaging Science is the investigation of the electromagnetic spectrum and its interaction with the environment for the exploitation of information. In other words: using light, heat, and other forms of radiation to perceive the environment in a way that humans cannot do naturally. Having studied engineering, I'm familiar with the cross-collaboration necessary to design and build aerospace systems.This generally includes a team of specialists familiar with their subsystems, but not able to independently perform an end-to-end analysis of the system as a whole. Conversely, Imaging Science gave me the opportunity to learn the physics, mathematics, and computer science necessary to perform a comprehensive end-to-end analysis on the entire "imaging chain.” The specialized nature of Imaging Science at RIT gives students the opportunity to be among those advancing the forefront of this discipline.

Building bridges - WiSTEE Connect

Mentoring connections can span generations for women in technical fields

Aug. 18, 2014
Susan Gawlowicz


Jie Qiao

By the time she reached midcareer, scientist Jie Qiao knew something was fundamentally wrong with the science-and-technology workforce. She was struck by the dwindling number of her female colleagues presenting at professional conferences or assuming leadership positions.

“There are a lot of reasons why women drop out of science,” said Qiao, an associate professor in RIT’s Chester F. Carlson Center for Imaging Science.

Many women feel isolated, lonely and taxed by competing demands of work and home, she noted. Others feel in need of mentorship, out of the loop, excluded from informal decision-making opportunities and disliked for their successes.

Qiao knows the scenarios firsthand as a woman in the male-dominated field of optics and photonics. She established her career developing technology for photonics, optical instrumentation and laser systems in laboratories in the corporate and academic sectors.

Outside of the laboratory, Qiao has a growing reputation as the founder and chairperson of an organization that brings together women in science, technology, engineering and entrepreneurship called WiSTEE Connect. Qiao launched the networking organization in 2013 at the University of Rochester and brought it to RIT later that year. The group has quickly grown into a regional organization.

“Promoting women and science is not my job, not my research,” she said. “I am doing this because of my passion for science and technology. I want to use my talent in my field and I also want other women to be able to use their talents. But there is a challenge for women to stay in this field.”

The response to the professional networking events Qiao has organized in China, UR, RIT and at an Optical Society of America conference confirms her belief that junior faculty and mid-career women need more support.

“Mid-career women are the bridge generation for connecting with more senior and more junior people,” Qiao said. “You have continuity. You look up and you see someone in front of you; you look back and you see your past. And that is motivating because you see the overall picture; you’re not isolated.”

Entrepreneurship is another key aspect of WiSTEE Connect.

“I wanted to introduce entrepreneurial thinking to the academic world,” said Qiao, who earned her MBA from the UR’s Simon Business School. “I recognized how important global marketing, strategy and leadership are to scientists and engineers. It brings a different perspective to a woman’s career. Entrepreneurial thinking helps academic women achieve a balance of opportunities, team and resources.”

WiSTEE Connect is a multidisciplinary and cross-ranking platform for providing an environment to foster a “mentorship ecosystem” and collaboration in the spirit of “cooperative advancement,” she said. Qiao envisions it growing into a national organization for women to share experiences, knowledge and strategies for mentoring, collaborating and navigating their careers as well as for overcoming unspoken stereotypical expectations.

“There is a lot of effort to get girls in science and engineering,” Qiao said. “But there is no point if they cannot grow through the field and have a fruitful career through their life.”

Connections in action

Jie Qiao had RIT students like Amanda Ziemann and Selene Chew in mind when she founded Women in Science, Technology, Engineering and Entrepreneurship Connect. The professional networking organization provides concrete support, mentorship and collaboration for students and young women on the cusp of their professional lives and through the rest of their careers. It bridges women at the junior and middle levels with those in leadership roles, said Qiao, an associate professor in RIT’s Chester F. Carlson Center for Imaging Science.

Ziemann and Chew gained professional perspective, opportunity and visibility—goals central to WiSTEE Connect—while attending the Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing in June with their mentors, RIT professors David Messinger and Nathan Cahill, respectively. Ziemann, a Ph.D. student in the Center for Imaging Science, presented a paper and co-chaired her first session, while Chew, a third-year computational mathematics major and honors student, gave a poster presentation at her first international conference.

RIT astronomers help find star ‘necklace’ connecting elliptical galaxies


(NASA, ESA and RIT) The NASA/ESA Hubble Space Telescope captured a cosmic moment of two merging cluster galaxies connected by a bright blue string of young stars.

Jul. 10, 2014
Susan Gawlowicz

Stars forming like a string of blue pearls along two elliptical galaxies could be the result of a galactic merger, according to an international team of astronomers. The structure could reveal rare insights about elliptical galaxies.

Scientists from Rochester Institute of Technology helped analyze data from the Hubble Space Telescope showing elliptical galaxies coalescing at the core of a dense galaxy cluster. The study is part of a program sponsored by the Hubble Space Telescope—an international cooperation between NASA and the European Space Agency—to look inside 23 massive clusters first catalogued in the Sloan Digital Sky Survey.

Findings of the study, “A thirty-kiloparsec chain of ‘beads-on-a-string’ star formation between two merging early type galaxies in the core of a strong-lensing galaxy cluster,” are available online, at http://arxiv.org/abs/1407.2251 and in an upcoming issue of The Astrophysical Journal Letters.

“These data were originally taken for a completely different purpose—to study the bluish arcs on larger scales in the cluster,” said Chris O’Dea, professor in RIT’s School of Physics and Astronomy and a co-author on the paper. “We were not expecting to catch these two elliptical galaxies in this spectacular burst of star formation.”

O’Dea and co-author Stefi Baum, professor and director of RIT’s Chester F. Carlson Center for Imaging Science, were thesis advisers and mentors of the paper’s lead author, Grant Tremblay, a post-doctoral fellow at the European Southern Observatory in Garching, Germany, and an inaugural alumnus of RIT’s astrophysical sciences and technology Ph.D. program. Tremblay will join Yale University as a NASA Einstein Fellow in September.

(NASA, ESA and RIT) A zoom-in shows the two merging central cluster galaxies in yellow/orange and the “beads-on-a-string” star formation in bright blue.

The 100,000-light-year-long structure identified in the Hubble data is dotted with 19 young, blue star clusters like pearls on a string, evenly spaced and separated by 3,000 light-years. The star necklace will lose its shape in about 10 million years as each of the 19 stellar superclusters follows a different orbit, Tremblay said.

Earlier observations of star clusters forming in evenly distributed clumps in spiral galaxies could explain Tremblay’s “serendipitous discovery” in the Hubble data.

“This phenomenon has never been seen before in merging elliptical galaxies,” Tremblay said. “We have two big monsters and they’re playing tug-of-war with this necklace.”

Tremblay and his team suggest three possible scenarios that could have created the string-of-pearl stars between two elliptical galaxies:

  • Merger—Coalescing galaxies triggered a reservoir of cold gas into star formation
  • Cooling flow of gas—Hot gas from the X-ray atmosphere around the galaxies cooled into puddles of cold molecular gas and started to form stars
  • Collision—A galactic collision created an X-ray shock catalyzing the star formation by compressing the gas and cooling the plasma.

“Compared to a galaxy’s lifetime of billions of years, star formation processes—which take millions of years—are quite brief,” said Kevin Cooke, graduate student in RIT’s astrophysical sciences and technology program. “To find such an event in early type galaxies where star formation is rare is an incredibly fortunate find. Research into star formation in galaxies helps address many fundamental questions about the universe, and this rare star formation event will help propel this field of knowledge.”

Tremblay’s team has a strong connection to his alma mater, RIT, with three co-authors from the university—Baum, O’Dea and Cooke. In addition to the RIT contingent, the team of scientists includes Michael Gladders, University of Chicago; Matthew Bayliss, Harvard University and Harvard-Smithsonian Center for Astrophysics; Håkon Dahle, University of Oslo; Timothy Davis, European Southern Observatory; Michael Florian, University of Chicago; Jane Rigby, NASA Goddard Space Flight Center; Keren Sharon, University of Michigan; Emmaris Soto, the Catholic University of America; and Eva Wuyts, Max-Planck-Institut für extraterrestrische Physik.

Taking Landsat 8 to the Beach (Summary)
Remote Sensing

Some things go perfectly with a summer trip to the coast: sunscreen, mystery novels, cold beverages, and sand castles. Other things—like algae blooms or polluted runoff—are a lot less appealing. The newest generation of Landsat satellite is helping researchers identify and study potential problem areas from space.

Most remote sensing satellites, including the long-running Landsats, detect the intensity of different wavelengths of light that reflect off of Earth’s surfaces, from forests to fields to cities. But water poses a challenge. It absorbs and scatters a lot of light, so oceans and lakes tend to look dark or lack detail on satellite images, especially in the murky waters near the coast. “All of the interesting stuff was typically lost in the noise of the old instruments,” said John Schott, a researcher at the Rochester Institute of Technology.

Landsat 8, however, has a new “coastal blue band” designed to parse out subtle differences in the color of water—minor changes in color intensity that can indicate what is mixed in that water. “Now we’ve got a possibility to see and figure out what’s causing color changes,” said Schott, a Landsat science team member. “It’s a potential revolution for studying water.”

The natural-color image at the top of this page was acquired on September 19, 2013, by the Operational Land Imager (OLI) on Landsat 8. It shows a southern shore of Lake Ontario near Rochester, New York, as it might appear to the human eye.

Beyond the blue of that water, Schott and his colleagues are paying close attention to three colors—green, yellow, and gray—to decipher what’s floating in Lake Ontario. Green wavelengths indicate the presence of chlorophyll, the molecule found not only in land plants but also algae and other phytoplankton. Yellow usually hints at the presence of decaying plant matter. Grays come from airborne particulates like dust and soil, or from dead algae that have lost their chlorophyll.

“It’s a classic color problem. All of these things together give the water a color,” Schott said. “You can unmix these to give you the components.” That’s exactly what his research team is now doing.

Over the past year, members of Schott’s research group have paddled or motored out into the lake to sample the waters on the same days that Landsat 8 has passed overhead (which happens once every 16 days). The team then compares the chemistry and visual quality of those water samples with what the satellite sees. The researchers are using these comparisons to create data tables and computer programs that will eventually turn remote satellite images into timely information for local managers of water quality.

The area inside the inset box of the top image is shown in scientific detail in the two lower images. The left map uses wavelength data from OLI to show the levels of chlorophyll in the lake and nearshore water bodies. Plants and phytoplankton use this pigment to convert photons of light into food. The lower right map uses Landsat data to show the amount of suspended sediment in the water. Silt, soil, sand, dissolved plant matter (from microscopic algae to leaves), and other floating debris naturally flow out from inland waterways to the coast, carrying both nutrients and pollutants.
