BME Researcher Gets Grant for Ovarian Cancer Screening Device

Jennifer Barton in the labProfessor of biomedical engineering Jennifer Barton has been awarded a four-year National Institutes of Health grant totaling nearly $1.3 million to develop a novel tool that would be used to identify the earliest signs of ovarian cancer.  

Barton, interim director of the UA's BIO5 Institute, is collaborating with Khanh Kieu, assistant professor of optical sciences, and Kenneth Hatch, professor of obstetrics and gynecology.

The new device, called a salpingoscope, would enable high-sensitivity, high-resolution imaging of the fallopian tube, ovaries and uterine wall. The scope would be used under local anesthesia in an office setting.

Student-Athlete Spencer Declares Her Major

One of the Wildcats highlighted at the event was sophomore gymnast Danielle Spencer, who shared her story of selecting biomedical engineering as a major. 

“I will be able to take my passion and hopefully improves the quality of life,” she said. “It gives me my reason and purpose. ... It helps me keep the best outlook on my life.”

UA Receives First NuPET Scanner in the Nation

The UA team are pairing the compact positron emission tomography scanner with a dynamic MRI technique to develop a novel preclinical approach for characterizing cancerous tumors

The dual-mode system aims to provide a more precise image and, ultimately, a quicker diagnosis.

"A single imaging mode is not enough to reveal all the permutations and gain a diagnostically useful understanding of what’s going on inside the tumor," said Pagel. “But, as we refine our approach, I’m confident that better interpretations will be made, and that could translate into better outcomes for patients.”

Their approach is based on a volume holographic imaging system.

They have successfully completed a clinical trial using a bench-top version of the device and are currently developing a handheld rigid endoscope version.

Associate professor of physiology and biomedical engineering Erika Eggers recently received two prestigious federal grants, totaling $2.8 million, to reduce the specter of blindness for millions with diabetes and deepen insight into how we see.

She is principal investigator of a $1.9 million project funded by the National Eye Institute of the National Institutes of Health, with additional support from the International Retinal Research Foundation, to study "Retinal Neuronal Signaling in Early Diabetes."  

She was also awarded a 2016 Faculty Early Career Development Award of $900,000 from the National Science Foundation, the agency’s most prestigious honor for junior faculty members.

Gmitro Helps Push the Boundary of Radiology with Biophotonics

Portrait of Art GmitroBiophotonics – the development and application of optical techniques for the study of biological molecules, cells and tissue – is expanding the scope of radiology by bringing clinicians and researchers new tools for noninvasive imaging of cancer and other diseases.

Department head and professor of biomedical engineering, medical imaging and optical sciences Art Gmitro is a pioneer of the interdisciplinary field, which incorporates medicine, biology, physics, engineering, technology and more. 

“Biophotonics is somewhat like magnetic resonance: a rich technology that can measure many different things,” he said. 

Students Create Cost-Effective, Easy-to-Use Medical Device

Engineering Design Team 15024 with their project posterAn incorrectly inserted nasogastric feeding tube can lead to serious injury or death.

But a UA College of Engineering senior design team featuring four biomedical engineering students is helping to mitigate the danger.

In May, they produced a working prototype of an instrument that gives instant feedback on tube placement.
