Developing Highly Sensitive Imaging Methods for Earlier Cancer Detection

Dr. Alla Reznik, a worldwide expert in photoconducting materials for x-ray and gamma-ray medical imaging detector applications, has investigated the properties of wide-bandgap semiconductors since the 1990s. She has spent most of her career developing advanced detectors including new solid state technologies for positron emission tomography (PET) imagers and low-dose x-ray fluoroscopy systems.

Most recently, Dr. Reznik led a research team to develop positron emission mammography (PEM). This technology improves accuracy of breast cancer detection at earlier stages – especially useful for women with dense breast tissue – by using molecular imaging. Further, PEM is not painful as is traditional mammography, which requires breast compression during imaging.

Her PEM research has led to the launch of Radialis Medical, which will produce a commercial version of the technology for breast cancer detection. It is the second spin-off company for the Health Research Institute, and the company hopes to develop and manufacture the PEM units right here in Thunder Bay.

Dr. Reznik, who is also a Canada Research Chair in Physics of Molecular Imaging, continues to work on the development of advanced radiation imaging detectors for a variety of biomedical applications including cancer diagnosis and treatment monitoring.
