Medical Imaging

Post by Christopher K. »

Dr. Joyoni Dey is an Assistant Professor in the Department of Physics and Astronomy at LSU with expertise on medical imaging and image reconstruction.
On All Saints Day at HRPO she will briefly illustrate the physics behind X-ray, CT, MRI and ultrasound with example images. She will also show case examples of Phase Contrast X-ray imaging, where interference of X-rays are used to image the phase-shift of the X-rays while propagating through the human body. The lecture has no admission fee and begins at 7:30pm.

Professor Joyoni Dey and personnel at CAMD have invented "modular phase gratings to produce visible x-ray interference fringes in clinical detectors without requiring an expensive fluence-absorbing analyzer". Dey is listed as the primary inventor. The invention has a U.S Patent Office number as of 22 December 2020.

On Friday 5 March at 6:30pm, Professor Dey will give the presentation "A New Medical Physics Patent" to describe the invention and its potential applications, including in mammography.
