On the Commissioning of CT-simulation in Radiotherapy Treatment Planning: A Phantom Study

摘要

The development of CT-simulation leads to major improvements in radiation therapy treatment planning. However it is not clear whether this new technology has evolved to the point of completely eliminating the “physical simulator”. At present there is an ongoing debate about the significance of virtual simulation in the treatment planning process and its limitations for different clinical purposes. The purpose of this study is to measure the accuracy in the determination of the isocenter in a virtual simulation process and to report about parameters which influence on the precision of its determination.
