Problems solved by technology

However, in realistic implementations, the actual values ​​of these parameters deviate from the included values ​​in the treatment plan by an error value caused by the determination of the parameters and / or in setting the parameters to the values ​​specified in the treatment plan inaccuracies caused by
These inaccuracies arise, for example, in the case of dwell locations, from errors that occur in the determination of the relevant location information

Embodiment Construction

[0044] figure 1 An embodiment of a system for delivering a brachytherapy treatment to a target structure within the body of a human or animal patient is schematically and exemplarily illustrated. The target structure may in particular be a tumor within a specific area of ​​the body, such as the prostate or the female breast. exist figure 1 In the exemplary embodiment shown in , the system is configured as a temporary brachytherapy system for delivering a high dose rate (HDR) brachytherapy treatment or another form of temporary brachytherapy treatment.

[0045] In a brachytherapy system, a target structure is irradiated by a radiation source that is temporarily placed in a treatment area near the target structure. The treatment may be delivered once or in small quantities (ie, the radiation source is placed multiple times in the treatment area).

[0046] The brachytherapy system comprises an applicator 1 for delivering a radiation source to a treatment area. The radiation s...

Abstract

The invention relates to a system and a method for assisting in planning a radiation therapy treatment, the treatment being delivered on the basis of a treatment plan including error-prone parameter values of first treatment parameters. In the system, a robustness evaluation unit (10) obtains planned parameter values of the first treatment parameters, generates perturbed parameter configurations including perturbed values of the first treatment parameters, the perturbed parameter values deviating from the planned parameter values by possible error values of the first treatment parameters occurring during the treatment, and estimates for each perturbed parameter configuration a radiation dose distribution resulting from a treatment delivered on the basis of the perturbed parameter configuration and / or determines the treatment plan on the basis of the perturbed parameter configurations.

Description

technical field [0001] The present invention relates generally to the planning of radiation therapy treatments, in particular brachytherapy treatments. More specifically, the present invention relates to systems, methods and computer programs for assisting in the planning of treatment plans for radiation therapy treatments of target structures within regions of a patient's body. Background technique [0002] In radiation therapy, targeted structures in a patient's body, such as tumors, are treated with radioactive or electromagnetic radiation or ultrasound in order to control the growth of cancer cells or to kill them. At the same time, the treatment is delivered in such a way that the radiation or thermal dose delivered to the surrounding healthy structures, often also referred to as organs at risk (OAR), is as low as possible. [0003] An exemplary radiation therapy procedure is so-called temporary brachytherapy, in which an applicator is used to place a radioactive radia...
