Photon-counting CT scanning is the next-generation of computer tomography diagnostics, providing precise, multi-color imaging to simultaneously track biological processes.
The Laboratory for Materials in Medicine, led by Dipanjan Pan, the Dorothy Foehr Huck & J. Lloyd Huck Chair Professor in Nanomedicine and professor of materials science and engineering and of nuclear engineering at Penn State, is advancing the imaging capabilities by developing contrast agents to target specific molecules and processes that may reveal more about disease progression than traditional scans.
