SINGLE-USE INTERNAL DOSIMETERS FOR DETECTING RADIATION IN MEDICAL PROCEDURES/THERAPIES
First Claim
Patent Images
1. An internal single-use radiation dosimeter, the dosimeter comprising:
- at least one radiation sensor circuit with a MOSFET having an associated threshold voltage that changes when exposed to radiation to provide quantifiable radiation exposure data, wherein the radiation sensor circuit is unpowered during irradiation;
electronic memory having radiation calibration data for the MOSFET; and
a reader contact zone on the dosimeter configured to allow a portable reader to electrically engage the dosimeter to obtain the radiation exposure and calibration data, wherein the radiation dosimeter is a single-use dosimeter configured for use during a single medical treatment session.
