## Indications for use
The AcQPlan 5.0 is an integrated 3-D RTP and simulation system embedded in a volumetric image processing computer environment. AcQPlan 5.0 is intended to be used to plan radiation therapy treatments on linear accelerators and other similar teletherapy devices with x-ray beams of energies from 4 to 50 MV, cobalt-60, and electron beams with energies from 4 to 50 MeV of the entire human anatomy. It allows the treatment planner to employ such techniques as asymmetrically collimated fields, irregular fields, multi-leaf collimators, non-coplanar fields, bolus, and fixed wedges. It allows the treatment planner to take heterogeneities into account (CT only) for photon beams using two versions of the Batho method or the Equivalent TAR (ETAR) method, and it uses a generalized Gaussian pencil beam model for electron beams. Using AcQPlan 5 .O, the treatment planner can simultaneously visualize target and normal tissues and the computed 3-D dose distributions in great detail, on a real-time basis. The treatment planner develops treatment plans in a coordinate system accurately fixed to set-up marks on the patient made possible by volumetric 3-D image processing. Tools for managing competing and complementary plans are provided. Tools, based on DVH plots, are provided for comparing competing plans. High quality DRS and DCS (digitally reconstructed or composited simulation) images, with BEV and beam graphics superimposed, are generated to replace conventional simulator films. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories.
