Abstract

A method is provided for providing a treatment plan for radiotherapy when delivery is interrupted, the method being performed by a treatment planning system. The method comprises the steps of: detecting that delivery of a first treatment plan has been interrupted; obtaining an indication of delivery of a partial dose representative of a portion of the first treatment plan delivered prior to the interruption; generating a second treatment plan, wherein the partial dose delivery is input to the second treatment plan generation as background dose formation; and optimizing the second treatment plan while taking into account the plurality of scenarios.

Description

technical field [0001] The present disclosure relates to the field of radiation therapy, and in particular to providing a treatment plan for radiation therapy when delivery is interrupted. Background technique [0002] In radiation therapy, one or more treatment beams irradiate a target volume. Various types of treatment beams can be used, such as photon beams, electron beams, and ion beams. The target region may represent a cancerous tumor. The treatment beam penetrates the tissue and delivers an absorbed dose to kill tumor cells. [0003] During a course of radiation therapy to a patient, the delivery of radiation therapy sometimes has to be interrupted. For example, interruptions may occur because patients need to go to the bathroom or for technical reasons. In the prior art, when the delivery of radiation therapy is resumed, the system simply provides the remainder of the delivery. [0004] However, when delivery is resumed, the patient may have moved or internal or...
