A radionuclide therapy treatment planning and dose estimation system.
UNLABELLED An object-oriented software system is described for estimating internal emitter absorbed doses using a set of computer modules operating within a personal computer environment. The system is called the Radionuclide Treatment Planning and Absorbed Dose Estimation System (RTDS). It is intended for radioimmunotherapy applications, although other forms of internal emitter therapy may als...
متن کاملComparing experimental assessment of the peripheral dose outside the applicator in electron beams of ELEKTA with Treatment planning system
Introduction: The use of electrons in the electron therapy to destroy tumoral tissue is dedicated significant contribution of different methods of radiation therapy. Scattered radiation due to exited electrons of the applicator affect the dose out of the field in the patient's normal tissue. The aim of this study is to determine the peripheral dose outside the applicator in the...
متن کاملImplementation of an Analytical Model for Leakage Neutron Equivalent Dose in a Proton Radiotherapy Planning System
Equivalent dose from neutrons produced during proton radiotherapy increases the predicted risk of radiogenic late effects. However, out-of-field neutron dose is not taken into account by commercial proton radiotherapy treatment planning systems. The purpose of this study was to demonstrate the feasibility of implementing an analytical model to calculate leakage neutron equivalent dose in a trea...
متن کاملMotion-compensated estimation of delivered dose during external beam radiation therapy: implementation in Philips' Pinnacle(3) treatment planning system.
PURPOSE Recent research efforts investigating dose escalation techniques for three-dimensional conformal radiation therapy (3D CRT) and intensity modulated radiation therapy (IMRT) have demonstrated great benefit when high-dose hypofractionated treatment schemes are implemented. The use of these paradigms emphasizes the importance of smaller treatment margins to avoid high dose to surrounding n...
متن کاملFir 1 Epithermal Neutron Beam Model and Dose Calculation for Treatment Planning in Neutron Capture Therapy
The epithermal neutron beam model of the Finnish boron neutron capture therapy (BNCT) facility (FiR 1) was created using the two-dimensional (2D) discrete ordinates transport (DORT) code. The final design of the beam was achieved using the DORT model: the optimal thickness of the neutron moderator and the length and the thickness of the bismuth collimator of the beam were calculated. The final ...
