Embodiment Construction

[0021] The detailed description and technical content related to the present invention are described as follows with reference to the drawings:

[0022] see first figure 1 , the present invention is a method for reconstructing dose distribution of a pen-tip proton beam scanning system for radiotherapy, comprising the following steps:

[0023] Step 1: place a detector 10 in a to-be-scanned area P of the pen-tip proton beam scanning system 20 to detect the pen-tip proton beam scanning system 20, such as figure 2 shown. see next image 3 . In the present invention, the detector 10 includes a first detection part 11 and a second detection part 12 overlapping with the first detection part 11 , the first detection part 11 includes a plurality of first detection components 111 , the The first sensing element 111 is in the shape of a long strip and extends along a first direction 110 , and the first sensing elements 111 are parallel to each other in sequence; the second detection...

Abstract

The invention provides a dose distribution reconstruction method for a pen-tip type proton beam scanning system for radiotherapy. Step 1: place the detector in the to-be-scanned area of ​​the pen-tip proton beam scanning system; Step 2: irradiate the pen-tip proton beam on the overlapping area of ​​the first detection part and the second detection part; Step 3: measure the pen-tip protons The intensity of the beam on the second sensing element is obtained to obtain the respective first one-dimensional intensity data of the first sensing segment; Step 4: Measure the intensity of the pen-tip proton beam on the first sensing element to obtain the second sense measure the respective second one-dimensional intensity data of the segment; Step 5: combine the first one-dimensional intensity data and the second one-dimensional intensity data to obtain two-dimensional intensity data of the associated pen-tip proton beam. Accordingly, those skilled in the art can correct or compensate the dose of the pen-tip proton beam scanning system according to the two-dimensional intensity data.

Description

technical field [0001] The invention relates to the field of radiotherapy, in particular to a more accurate dose distribution reconstruction method of a pen-tip type proton beam scanning system. Background technique [0002] Century changes, civilization evolves. After the millennium, it can be said that human civilization has entered a new era, and technologies such as information, biology, aerospace, and medical treatment have made great progress. Among them, the innovation of medical technology has made a great contribution to human life. However, even though most of the current medical technology can easily cure common diseases, there are still some cases that are more difficult, for example, the complications of cancer. [0003] People in the medical field try their best to find ways to cure cancer, such as tumor resection, chemotherapy, targeted therapy and other treatment methods. Recently, radiation therapy is also used, that is, the use of radiation to irradiate th...
