Intern Class of 2011: Elaine Ferrara

Recently, CIS caught up with Elaine Ferrara, one of our summer interns back in 2011. She reminisced about her internship experience and updated us on what she's up to now.

CIS Student Enhances Digital Reconstruction of Tumors: Presents Findings at San Diego Medical Imaging Conference

By Amy Mednick

Biomedical researchers now have access to a more elegant method to digitally reconstruct microscopictissueslices, or histological sections, of tumor specimens into three-dimensional models thanks to the work of Shaohui Sun. Sun—a Center for Imaging Science graduate student—presented his findings in February at the SPIE Medical Imaging Conference on Image Processing in San Diego.

CIS Professor Nathan Cahill discovered the problem in a conversation with Nzola de Magalhaes, a RIT Biomedical Engineering professor who studies tumor vascularization. Magalhaes wanted to find a way to stack successive histological sections of tumors in chicken embryos to eliminate the usual distortion and registration problems associated with digital reconstruction of these images.

Innovative Image De-Noising Method Helps Diagnose Schizophrenia

Reported by Amy Mednick

Clinicians across the world now have access to an image de-noising “toolbox” that will allow them to improve the diagnosis and treatment of their patients with schizophrenia or bipolar disorder. This pre-processing algorithm enables scientists to compare, with greater specificity, brain scans of schizophrenic patients and healthy control subjects.

            Siddharth Khullar, a second year doctoral student at RIT’s Chester F. Carlson Center for Imaging Science, is pioneering new techniques that calibrate functional magnetic resonance imaging (fMRI) in more precise detail, allowing scientists to discern brain functionality of schizophrenic patients better than ever before.
