Differentiation between primary and metastatic lesions in treatment planning. The radiation therapy system according to the embodiment includes a specific section and a classification section. A specific portion identifies at least one tumor area from a medical image of a patient. The classification part...
SBRT involves technically sophisticated treatment planning processes consisting of a chain of activities including: immobilization/simulation, motion management, imaging for treatment planning, segmentation, beam-setup and optimization, and plan verification. Clinicians are usually concerned of a possible ...
Method of radiation therapy treatment planning
In the present work, the Monte Carlo method was used to develop a computer code for determining absorbed dose distributions in orthovoltage radiation therapy. The code was used in planning treatment of a patient with a neuroendocrine carcinoma of the maxillary sinus. Two lateral high-energy photon...
Identifical treatment plans on all three CT data sets for each patient pointed out differences in: (a) radiation path lengths; (b) positions of the organs; (c) physical volumes of the lung, liver, and kidneys; (d) the interpretation of plan evaluation tools such as dose-volume histograms ...
Optimization of a treatment plan for radiation therapy will produce a plan with the highest probability for tumor control without exceeding an acceptable c... JT Lyman - 《Radiat Res Suppl》 被引量: 2146发表: 1985年 Calculation of complication probability factors for non-uniform normal tissue irra...
A method for determining a radiation treatment plan for a radiotherapy system providing multiple individual rays of intensity modulated radiation iteratively optimized the fluence of an initial set of such rays by a function that requires knowledge of only the prescribed dose and the dose resulting fro...
Modern cancer therapy has benefited enormously from computer controlled treatment devices with increased precision and capability. However, this increased sophistication also creates new challenges for treatment planning. As the number of parameters in a treatment plan increases, the traditional computational ...
In this work, a graphical method for radiotherapy treatment plan assessment and comparison, named SPIDERplan, is proposed. It aims to support plan approval allowing independent and consistent comparisons of different treatment techniques, algorithms or treatment planning systems. ...
