Abstract
The aim of this publication is to review the requirements necessary for using computed tomography (CT) for radiotherapy treatment planning. The equipments were tested with different CT phantoms. The authors made several measurements for checking the CT number, the quality and the mechanical parameters of CT tables. The CT numbers measured on the equipments of different manufacturers were in quite good agreement with the IAEA requirements. The geometric distortions of CT images are negligible, while the mechanical parameters of CT tables show considerable variety. A quality assurance - quality control protocol is recommended to implement in a safe workflow.
