clinical physics staff, 17 dosimetrists, 2 physics residents, 17 MD radiation
oncology faculty, and 4 medical residents.  We plan to add more physicists to our staff in 2022.  The Division of Radiation Oncology currently treats over 3000 patients annually on 19 state-of-the-art treatment units (15
Elekta VersaHD) and 5 Elekta HDR Flexitrons across 14 facilities.  Each facility houses a 4-D CT scanner.

The Therapy Residency Program is based at the new academic cancer center at Allegheny General Hospital (AGH), where houses the state-of-the-art machines including an Elekta Unity MR-Linac, two Elekta VersaHDs, Exactrac Robotic system, a GammaKnife Icon, a GammaPod, and an Elekta HDR Flexitron.  Adding an MR simulator and possibly a research MR scanner are planned in near future.
