This paper describes a SimMechanics model of the computer controlled patient support system. The first part of the paper describes the aim of the Elekta Synergy radiotherapy treatment machine and in particular the new automatic patient support system (PSS). The second section describes the mechanistic model implemented using the SimMechanics toolbox. The third section describes the implementation of a discrete PID controller onto the PSS microcontroller. The control system is used to demonstrate the ability of the model to replicate the PSS behaviour and highlights that the new PSS control system is able to position patients with a very high accuracy.
