Treatment Couch Modeling in the Treatment Planning System Eclipse
The treatment couch and some of the positioning devices of patients receiving radiotherapy treatment are made of a material (carbon) which has low attenuation properties for the photon energies used in the radiotherapy. Previous investigations showed the suitability of carbon fiber tabletops in radiotherapy and their very low attenuation properties for a range of X-ray energies and field sizes ...
متن کاملComparing planning time, delivery time and plan quality for IMRT, RapidArc and tomotherapy
The purpose of this study is to examine plan quality, treatment planning time, and estimated treatment delivery time for 5- and 9-field sliding window IMRT, single and dual arc RapidArc, and tomotherapy. For four phantoms, 5- and 9-field IMRT, single and dual arc RapidArc and tomotherapy plans were created. Plans were evaluated based on the ability to meet dose-volume constraints, dose homogene...
متن کاملInvestigation of probabilistic optimization for tomotherapy
This work builds on a suite of studies related to the 'interplay', or lack thereof, for respiratory motion with helical tomotherapy (HT). It helps explain why HT treatments without active motion management had clinical outcomes that matched positive expectations. An analytical calculation is performed to illuminate the frequency range for which interplay-type dose errors could occur. Then, an e...
متن کاملModeling, Simulation and Optimization of Process Planning
Designing of production systems from the standpoint of necessary resources for carrying out the production process for many years present an important set of engineering tasks. In the scope of design of production systems, in addition to design of process planning, it is necessary to make the determination of normative parameters, by which the effectiveness of the production process will achiev...
متن کاملOptimization of tomotherapy treatment planning for patients with bilateral hip prostheses
BACKGROUND To determine the effect of different imaging options and the most efficient imaging strategy for treatment planning of patients with hip prostheses. METHODS The planning kilovoltage CT (kVCT) and daily megavoltage CT (MVCT) studies for three prostate cancer patients with bilateral hip prostheses were used for creating hybrid kVCT/MVCT image sets. Treatment plans were created for kV...
