Verification of the precision and accuracy of the TPS dosimetric calculations using the 3.0 version MIRS TECDOC-1583 of the IAEA (2008)

Radiotherapy is one of the basic therapeutic tools to treat malignant tumors. The treatment of a tumor with ionizing radiation is a continuous process with distinct stages, which is the computerized planning, being a fundamental component within this process, it is in this phase are designed and calculated the patient treatment. Systems for Radiotherapy Treatment Planning (TPS) are the tools to perform the treatment planning. The Radiotherapy Service of the Hospital Hermanos Ameijeiras acquired MIRS software version 3.0, which has potential as conventional radiation therapy planning tools and compliance with 3D, multiple imaging studies and calculation of dose according to patient data and equipment. For the complexity of these calculations and the reliability which must have the same, the software should be subjected to rigorous acceptance testing. We verify the precision and accuracy of the TPS dosimetric calculation by applying the most recent protocol of acceptance of the IAEA for these systems (2008). After implementation of the testing set is unable to verify the dose calculations are within the tolerances allowed. (Author)
