Patent ID: 7491942

Claim:
A method for monitoring radiation exposure for a patient undergoing a medical procedure, comprising: inserting a single-use dosimeter into a patient, wherein the at least one dosimeter comprises at least one radiation sensor circuit with a MOSFET and electronic memory that holds calibration data for the MOSFET; exposing the patient to radiation in a medical procedure during a treatment session; transmitting data from the dosimeter to a dose-reader device after the exposing step, the transmitting data comprising the calibration data and data associated with a change in an operational parameter in the MOSFET of the dosimeter radiation sensor circuit; removing the dosimeter from the patient after the exposing step during or proximate in time to the treatment session; and determining a radiation dose received by the patient during the exposing step based on the change in the operational parameter of the MOSFET and the calibration data.
