This paper continues the discussion on the commissioning tests performed on a new GE Lightspeed RT wide-bore computed tomography (CT) scanner, focusing on the GE Advantage Sim software (version 6.0).
The tests performed and phantoms used to assess the virtual simulator functionality, including the 3D image display, contouring, treatment unit beam parameters, digitally reconstructed radiograph generation and image quality, isocentre generation and multi-modality image registration, are described.
The series of tests performed showed the virtual simulation software to be working within acceptance tolerances suggested in the literature and baseline data have been obtained against which future comparisons of system performance have been made. Where no tolerances were available, we have suggested suitable values.
