Clinical Services

At Thomas Jefferson University Hospital's Bodine Center for Cancer Treatment there are two Elekta linear accelerators equipped with 4D cone beam CT, EPID, and are commissioned for TBI. There are also two Varian TrueBeam linear accelerators equipped with cone beam CT and EPID, as well. All four linacs are capable of delivering IMRT, VMAT, stereotactic radiotherapy, and utilize MOSAIQ record and verify systems.

Other technology in use includes accessories for SRS, SRT, TBI, IORT, automated breathing coordination, custom patient immobilization, HexaPod automatic table positioning with six degrees of freedom, and AlignRT, a system capable of real time patient surface monitoring.

The department is equipped with one CT simulator with 4D capabilities (GE LightSpeed-16 with Advantage Workstation and Varian RPM), one Nucletron Simulix simulator with cone beam CT capabilities, and a block cutting and mold room. We have a well-established LDR (Varian Variseed) brachytherapy program for prostate seed implants and HDR (Nucletron Oncentra) brachytherapy program for breast, gynecological, skin, and prostate cancer along with microsphere brachytherapy for liver cancer. Treatment planning tools consist of full 3D capabilities for both photons and electrons along with IMRT and VMAT (XiO, Monaco, and Eclipse planning systems). 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 ARIA 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 administers the MOSAIQ record and verification system. There is a dedicated Phillips Acusim CT simulator and five Pinnacle 3D/IMRT planning systems.

Riddle Memorial Hospital has an Elekta linac with mixed modalities, XiO treatment planning system and Focalism.

Methodist Hospital has a Varian Clinac 2100 CD, a Ximatron classic simulator, MOSAIQ, and XiO treatment planning system.

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, an OSL dosimetry system for in-vivo measurements, film densitometer, two water tank dosimetry systems, 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. There are two diode arrays used for patient specific IMRT and VMAT QA, the MapCheck and Delta4.

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.
