Comparison between the SGRT and the conventional setup method for patients undergoing VMAT for pelvic malignancies.

Purpose: Surface Guided Radiation Treatment (SGRT) is a new method of positioning and monitoring patients on the linear accelerator's couch, using visual light cameras to monitor the skin's surface. The purpose of this study was to compare the SGRT with the conventional method, based on lasers and tattoos, in terms of accuracy and time expenditure, on patients with pelvic malignancies.

Materials And Methods: A group of 34 patients were enrolled in this study, 24 males who underwent radiotherapy prostate treatment and 10 females who underwent gynecological radiation therapy.

Organ dose prediction for patients undergoing radiotherapy CBCT chest examinations using artificial intelligence.

Purpose: To propose an artificial intelligence (AI)-based method for personalized and real-time dosimetry for chest CBCT acquisitions.

Methods: CT images from 113 patients who underwent radiotherapy treatment were collected for simulating thorax examinations using cone-beam computed tomography (CBCT) with the Monte Carlo technique. These simulations yielded organ dose data, used to train and validate specific AI algorithms.
