  Purpose: Previously in treatment planning systems (TPS) the treatment couch was expected to be made out of air-equivalent material due to the used material (Carbon). Some studies have already shown that the treatment couch cannot be neglected during treatment planning. Nowadays the manufacturer of TPS implemented the feasibility to insert treatment couch structures. This study aimed to find the correct modeling of the treatment couch parameters in the TPS Eclipse. Method: The Varian Exact Treatment Couch consists of a carbon board (length 2.5 cm) and two moveable rails (length 8.5 cm) underneath. The treatment couch can be modeled in TPS by changing the Hounsfi eld units (HU) for each part of the treatment couch. For low and high photon energies the attenuation of the treatment couch was measured at a Clinac 2300 C/D and in the TPS the attenuation of the treatment couch model was de.. Read More»
