Dr. Goldan has received a new NIH grant entitled “SWAD: Large-Area Photon Counting X-Ray Imager Using Amorphous Selenium”.

In this NIH R01 grant, we proposed to develop a prototype hyperspectral photon counting imager using the field-Shaping multi-Well Avalanche Detector (SWAD) for high spatial resolution contrast-enhanced x-ray breast imaging. Given that the photosensor material is amorphous, the detector structure is inherently inexpensive, and thus, it enables a cost-effective imager design with large area scalability. Also, the photon counting imager will permit quantum-noise-limited performance, energy weighting, high frame-rates, and multi-energy thresholding. The technological innovation we develop will lead to the widespread clinical application of a more efficient and lower dose contrast-enhanced cancer screening system for mammography.
