Research
At Thomas Jefferson University Hospital's Bodine Center for Cancer Treatment there are four Elekta linear accelerators, two are equipped with ConeBeam CT and EPIDs, one is equipped with EPID and MLC and one is equipped with MLC and commissioned for TBI. All four linacs utilize MOSAIQ record and verify systems.
Accessories for SRS, SRT, TBI, IORT, ABC, and custom patient immobilization, HexaPod automatic table positioning with six degrees of freedom, and automated patient assisted set-up and a home-developed video system for fast and accurate patient repositioning and monitoring of patient motion are in use.
The department is equipped with one CT simulator with 4D capabilities (GE LightSpeed-16 with Advantage Workstation and Varian RPM), one Philips SLS classic simulator, and a block cutting and mold room. We have a well-established LDR (Nucletron FIRST) and HDR (Nucletron V2) brachytherapy program and microsphere brachytherapy. Treatment planning tools consist of full 3-D capabilities for photons and electrons (CMS XiO and Focalsim with clinical and research versions), IMRT (XiO and Elekta PTI). We have multiple treatment planning stations so that training is done in parallel with clinical service.
Jefferson Center for Neurosurgery has SRS/SRT. There is a Novalis 6MV BrainLab microcollimator with Varis R+V system and ExacTrac image guidance system with two infrared tracking cameras and stereoscopic kV imaging (two kV digital imaging systems). JHN also is equipped with a Gamma Knife 4C with Automatic Positioning System. There are three BrainScan planning systems, one GammaPlan 5.x RTP, and an XKnife Radionics RTP used strictly for research.
Aria Health (formerly Frankford-Torresdale Hospital) has two Varian linacs, one 2100C and one Trilogy with on-board-imaging. Both machines are mixed modality energies and have Varis Vision electronic portal imaging capabilities. The department has MOSAIQ record and verify system; they are 100% filmless and 50% paperless. There is a dedicated Phillips Acusim CT simulator, five ADAC 3D/IMRT planning systems and one Varian Eclipse 3D planning system. The physics equipment includes multiple farmer chambers, one small water tank, one electrometer, in-vivo dosimeters, and a Profiler tracker for morning warmups.
Riddle Memorial Hospital has an Elekta linac with mixed modalities, CMS XiO treatment planning system and Focalsim.
Methodist Hospital has a Varian Clinac 2100 CD, and a Ximatron classic simulator, IMPAC, CMS XiO treatment planning system, Focalsim and an established LDR prostate brachytherapy program utilizing Varian Varisseed and real time dosimetry.
Dosimetry laboratories are available to the program at Jefferson Bodine Center, Methodist, Riddle Memorial, and Aria Health (formerly Frankford-Torresdale). We have standard and specialized ion chambers, diodes for photon and electron beams, TLD annealing ovens and automated TLD readers, film densitometer, one water tank dosimetry system, a linear diode array for dosimetry of IMRT plans, three humanoid phantoms for dosimetry, an IMRT and a CT phantom and a supply of tissue, bone and lung equivalent plastic slabs.
At the Bodine Center, a machine shop located in the clinical area is used by the clinical physics staff. This machine shop is operated by a full-time machinist and is available for clinical and research projects. There is an in-house Bioengineering shop in the Physics Division of both Jefferson and Aria hospitals and there are five full time engineers available for machine support.
