AbstractID: 8043 Title: The Midwest Proton Radiation Institute Project at the Indiana University
Cyclotron Facility
The Indiana University Cyclotron Facility (IUCF) cyclotrons ceased delivering particle beams for physics research in 1999 and the physics research space is
now being converted into a regional proton therapy center called the Midwest Proton Radiation Institute (MPRI). The renovation of the IUCF facility will
provide space for three patient treatment rooms, two research rooms and a clinic. The first treatment room will contain a large-field fixed horizontal beam
outfitted with a robot patient positioner and a magnetic beam spreading system as well as an eye line for treating eye diseases. The other treatment rooms
will be equipped with isocentric rotating gantries. Two rooms will be equipped for radiation research purposes. The clinic includes areas for patient
reception, examinations, preparation and immobilization areas and treatment planning. An achromatic beam-line (trunk line), will deliver up to 500nA of
205 MeV protons from the existing IUCF cyclotrons to a beam dump. Each of the three treatment rooms may draw protons on a time-share basis from the
trunk-line via fast switching magnets located at the entrances to the energy selection systems upstream of each of the treatment rooms. The cyclotrons will
also support full time research in radiation effects, single event upset, radiation biology and pre-clinical research in the research rooms. We expect to
complete construction of the first treatment room, one research room and the clinic by the end of 2002. The first patient treatment is projected for April
2003. This contribution describes the status of the medical construction project.
