Status Report for the Harper Hospital Superconducting Cyclotron Neutron Therapy Facility
نویسندگان
چکیده
During the past three years the number of neutron therapy patients treated at the Gershenson Radiation Oncology Center has remained approximately constant. The facility is operating at maximum load, approximately 9500 fields per year. In the present paper, data for the clinical load and usage of the cyclotron, since it entered routine clinical operation March 1992 are presented, together with data on machine downtime for the period March 1993 – February 2001. Recent and ongoing cyclotron improvement projects are described, including redesign work on the ion source, the beryllium target, the cryogenic and vacuum systems. The major improvement project, however, is the construction of a computer controlled multileaf collimator (MLC) to replace the existing multirod collimator[1] (MRC), which has been in use since patient treatments started in September 1991.

The clinical cyclotron facility in Seattle continues to provide beams for neutron therapy and PET isotope production. Over 2000 patients have so far been treated using an isocentric gantry with multi-leaf collimator. Downtime remains below 2%. A new therapy control system has been in operation for nearly two years now and works efficiently and reliably. Developments to extend the therapeutic wi...
متن کاملOperational Status of the University of Washington Med- Ical Cyclotron Facility
The University of Washington Medical Cyclotron Facility (UWMCF) is built around a Scanditronix MC50 compact cyclotron that was commissioned in 1984 and has been in continual use since. Its primary use is in the production of 50.5 MeV protons for fast neutron therapy. While this proton energy is too low for clinical proton therapy, it is ideal for proton therapy research in small animal models. ...

The INFN LNS Superconducting Cyclotron has been operating for almost 20 years. Several beams are currently accelerated and delivered, allowing for a wide variety of experimental activity to be carried out. In addition, clinical activity is regularly accomplished: over 11 years of proton-therapy of the eye pathologies, around 300 patients have been treated. This has stimulated a growing number o...

Background: Boron Neutron Capture Therapy (BNCT) is a very promising treatment for patients suffering gliobastoma multiforme, an aggressive type of brain cancer, where conventional radiation therapies fail. Thermal neutrons are suitable for the direct treatment of cancers which are located at near-tissue-surface deep-seated tumors need harder, epithermal neutron energy spectra. Materials and Me...
