What is Wedge Transmission Factor in Radiation Therapy about?

The document details the calculation of the wedge transmission factor for a 45° physical wedge used in radiation therapy, emphasizing its impact on monitor unit (MU) calculations to ensure accurate dose delivery to patients. Measurements were taken with and without the wedge using a Varian Trilogy linear accelerator, revealing a transmission factor of 0.497 and a 3.3% difference from the Eclipse treatment planning system. The importance of accounting for wedge attenuation in treatment planning is highlighte
