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.

Introduction: This paper describes a method to improve gantry-dependent beam steering for Elekta traveling wave linear accelerators by applying the measured and filtered beam servo corrections to the existing lookup table (LUT). Beam steering has a direct influence on the treatment accuracy by affecting the beam symmetry and position. The presented method provides an improved LUT with respect to the default Elekta method to reduce treatment delivery interruptions.

Purpose: To investigate risk factors for esophageal fistula in esophageal squamous cell cancer (ESCC) patients who treated with volumetric modulated arc therapy (VMAT).
Patients And Methods: A retrospective analysis was performed on 171 ESCC patients treated with VMAT at Hefei Cancer Hospital, Chinese Academy of Sciences, from February 2017 to February 2021. Clinical and dosimetric parameters, including age, gender, feeding channel, tumor location, T stage, ulcerative tumor, were recorded.

Objective: To evaluate the intra-fraction and inter-fraction positional deviations in head and neck tumor patients undergoing intensity-modulated radiation therapy (IMRT) guided by cone-beam CT (CBCT), as well as the correction capability and stability of the HexaPOD evo RT 6D couch in addressing these deviations.
Methods: From May 2019 to April 2022, 59 consecutive patients with head and neck tumors were enrolled at the Department of Radiation Oncology, Peking University Third Hospital.Using the Elekta AXESSE image-guided stereotactic treatment system, a pre-treatment CBCT scan was performed, followed by bone window mode registration with the planning reference images.
