First Claim
Patent Images
1. A method for monitoring radiation administered to patients undergoing radiation a therapeutic treatment, comprising the steps of:
- releasably securing at least one single-use dosimeter sensor patch comprising electronic memory to be in intimate contact with the skin of the patient such that, during irradiation, the patch is self-contained;
obtaining data associated with a change in an operational parameter in the at least one patch electronic memory using a dose reader, the patch electronic memory being configured with data including instructions that direct how the dose reader communicates with the at least one patch and/or obtains data stored in the patch electronic memory; and
determining a radiation dose received by the patient based on the obtained data of the change in the operational parameter.

Abstract
Methods, systems, devices, and computer program products include positioning disposable single-use radiation sensor patches that have adhesive means onto the skin of a patient to evaluate the radiation dose delivered during a treatment session. The sensor patches are configured to be minimally obtrusive and operate without the use of externally extending power chords or lead wires.
