RADIATION SENSING FIELD EFFECT TRANSISTOR (RADFET) FOR MEDICAL USE Reliable measurements of ionizing radiation administered during cancer treatments are now possible through a radiation dosimetry system developed by Sandia National Laboratories in collaboration with the University of New Mexico Cancer Center. Sandia's dosimeter technology also provides increased versatility in monitoring the exposure of medical personnel to ionizing radiation. The RADFET can be inserted in a medical catheter for in vivo measurements of cancer therapy radiation doses. The microsensor provides an immediate readout to determine if the accurate dose is being administered or whether nearby bones or other body parts have affected distribution of the radiation. It is especially well suited for use in brachytherapy. The RADFET can also be designed and configured to meet ionizing radiation detection requirements for a broad range of dosimeter applications. It provides total dose measurement in real time, and retains a permanent record of the ionizing radiation exposure. Dose readings remain after the dosimeter has been electronically interrogated, and when electrical power is lost to the sensor. Sandia is making the RADFET available to companies interested in partnering with Sandia to commercialize this invention. Partnering can take the form of cooperative research efforts with Sandia, and licensing of the intellectual property on terms up to, and including exclusive licenses in applicable fields of use. For further information, please respond to Joanne Trujillo not later than 28 August, 1998, at: Sandia National Laboratories, MS 1380, P.O. Box 5800, Albuquerque, New Mexico 87185-1380. FAX: 505-843-4163. Please indicate the date and title of this CBD notice and the type of partnering agreements your company would be most interested in pursuing with Sandia.
