چکیده

Along with innovative ideas for treating non static tumours comes the need of a 4D supporting treatment planning software. The GSI code treatment planning for particles (TRiP) [1;2] has recently been extended to 4D capabilities (TRiP4D) [3]. The status of TRiP4D has proceeded to a level which allows the first four dimensional uncertainty simulations. The sum of all uncertainties present at treatment time lead to a change in the estimated dose distribution. A major challenge to uncertainty consideration in general but especially in case of 4D treatment is their visualization. We are currently working on various concepts of communicating errors by easy and intuitive visualization.

Calculation of absorbed dose in lung tissue equivalent and compared it with prediction of a treatment planning system using Collapsed Cone Convolution algorithm

External radiotherapy is used for treatment of various types of cancers. Due to the impossibility of measuring the absorbed dose delivered to different organs during irradiation, treatment planning systems (TPSs) have been utilized for calculation of absorbed dose before a radiotherapy procedure. Thus, the accuracy and precession of the TPS is essential.The aim of this study is investigation of...

Simulation and visualization of dose uncertainties due to interfractional organ motion.

In this paper, we deal with the effects of interfractional organ motion during radiation therapy. We consider two problems: first, treatment plan evaluation in the presence of motion, and second, the incorporation of organ motion into IMRT optimization. Concerning treatment plan evaluation, we face the problem that the delivered dose cannot be predicted with certainty at the time of treatment p...
