High-accuracy quality control method of CT system couch tops for treatment planning via an advanced 3D coordinate measuring machine.

ABSTRACT:

Background

Quality control (QC) methods for computed tomography (CT) systems used in treatment planning have not been updated since the release of the Task Group (TG) 66 report by the American Association of Physicists in Medicine (AAPM) in 2003. Conventional QC methods for CT systems fail to fulfill the requirements of high-precision radiation therapy. Moreover, because the geometric accuracy of CT systems can affect the accuracy of radiation therapy, which is particularly critical in high-precision radiation therapy, a highly accurate QC method is required.

Purpose

This study aimed to develop a high-accuracy QC method for CT system couch tops suitable for high-precision radiation therapy by utilizing a wide-area three-dimensional (3D) coordinate measuring machine (3D-CMM),
