Helax-TMS is a 3D radiotherapy treatment planning system for radiation dose planning but not treatment, of patients undergoing external beam or Brachytherapy treatment in the Oncology clinic. The system is designed to lead the user through a logical flow planning process.
Based on quality assured radiation therapy input data Helax-TMS is used to plan radiation treatments with
(i) linear accelerators with X-ray energies from 4 to 50MV and electron energies from 4 to 50MeV as well as cobalt-60 units. Helax-TMS will plan 3D radiotherapy treatment approaches of combined modality plans, asymmetric and non-coplanar fields; total body irradiation; multi-leaf collimators; motorized and dynamic wedges; customized blocking; compensating filters; and bolus.
(ii) Brachytherapy units for patients undergoing interstitial or intracavitary treatment in the Oncology clinic.
Export capabilities exists as part of Helax-TMS to verify beam and patient data, dose planning results, and provide on-line information to block-cutting devices and milling machines, multi-leaf collimator control units, as well as record and verify systems.
