Tracking and Verifying HDR Brachytherapy Treatment Using an External Imaging Panel on the Treatment Table

What this Trial Is About

This research aims to collect data during High Dose Rate HDR brachytherapy treatments to track the brachytherapy source inside patients. The goal is to verify that the treatment plan is being delivered accurately and to detect errors or motion that are not currently monitored. The study involves patients receiving HDR brachytherapy for gynecologic endometriumcervix or prostate cancer, treated on a CT couch. An external imaging panel the investigational product will be positioned beside the treatment table to continuously acquire data throughout the treatment. This device will not touch the patient or change the clinical workflow, as it is placed at a safe distance and powered by two cables integrated neatly with the treatment table setup. The data collected will be compared against the planned treatment information to identify discrepancies and improve treatment verification. Participants will undergo their usual HDR brachytherapy treatment while the external panel collects data automatically during radiation exposure. Clinical staff will not need to perform additional actions. The data analysis will be done offline after treatment sessions to avoid interruptions. The primary outcomes measured are dwell times and dwell positions during treatment within one year. The total participation duration depends on the patients treatment schedule.
