Prevention of gross setup errors in radiotherapy with an efficient automatic patient safety system
Treatment of the wrong body part due to incorrect setup is among the leading types of errors in radiotherapy. The purpose of this paper is to report an efficient automatic patient safety system (PSS) to prevent gross setup errors. The system consists of a pair of charge-coupled device (CCD) cameras mounted in treatment room, a single infrared reflective marker (IRRM) affixed on patient or immob...
متن کاملA Simulation Study on Patient Setup Errors in External Beam Radiotherapy Using an Anthropomorphic 4D Phantom
Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...

متن کاملTowards Automatic, Model-Driven Determination of 3D Patient Setup Errors in Conformal Radiotherapy
The accurate and quantitative determination of three-dimensional patient setup errors in conformal radiotherapy, including setup errors due to out-of-plane rotations, requires methods for registering pre-treatment, three-dimensional planning CT images with intra-treatment, two-dimensional portal images. We have developed a method for performing such a registration based on structural models tha...
متن کاملImage-guided prostate radiotherapy: analysis of inter- fractional setup errors
Introduction: The accuracy of the patient setup and tumor location are major factors that determine the efficacy of radiotherapy treatment planning. In the prostate radiotherapy, reproducibility of the prostate location for each treatment fraction is problematic owing to varying filling of the rectum and bladder. According to this, the aim of this study was to measure the inte...
