About AHN

Allegheny Health Network is a Pittsburgh-based healthcare system. For more information about Allegheny Health Network see The Department of Radiation Oncology currently employs 9 PhD. physics faculty, 10 clinical physics staff, 20 dosimetrists, 3 physics residents, 23 MD radiation
oncology faculty, and 4 medical residents.  We plan to add more physicists to our staff in 2023.  The Division of Radiation Oncology currently treats over 3000 patients annually on 19 state-of-the-art treatment units (15
Elekta Versa HD and an Elekta Unity MR-Linac) 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 Versa HDs, Exactrac Robotic system, a Gamma Knife Icon, a GammaPod, and an Elekta HDR Flexitron.  Adding an MR simulator and possibly a research MR scanner are planned in near future.
