The Midwest Proton Radiotherapy Institute (MPRI)was designed by the Indiana University Cyclotron Facility (IUCF)to deliver proton radiation treatment to patients with solid tumors or other diseases susceptible to radiation. The IUCF Proton Therapy System (PTS)has five unigue subsystems to perform the radiation treatment; Beam Delivery, Dose Delivery, Patient Positioning and Treatment Control systems. The MPRI Clinic began operations in 2003 with a single Fixed Horizontal Beam Line (FHBL)treatment room and is being expanded to include two additional treatment rooms utilizing modified IBA* 360 degree rotating gantry systems. The Gantry nozzles use a beam wobbling and energy stacking system to produce the lateral and longitudinal beam distributions required for patient treatment. A treatment control system** provides a single user interface to deliver and monitor Proton Therapy treatment. This paper will present an brief overview of the Proton Therapy Facility, the properties and examples of the beam performance of the unique Nozzle design, and a summary of the facility beam operations.
