Embodiment 1

[0029] figure 1 It shows a flow chart of a radiotherapy plan presentation method provided by the first embodiment of the present invention. In this embodiment, the "first two-dimensional dose image sequence" and the "second two-dimensional dose image sequence" "One" and "Second" are only used to distinguish two different sequences and have no practical meaning. The details are as follows:

[0030] Step S11, receiving the first two-dimensional dose image sequence, the first two-dimensional dose image sequence is composed of a series of dose image planes arranged in sequence in space and parallel to each other, and the dose image plane consists of three-dimensional dose space containing thickness , length and width of the sampling grid set, each grid in the dose image plane is a voxel, and the value contained in the voxel is the dose value of the position of the voxel with respect to the three-dimensional dose distribution.

[0031] In this step, the value contained in the voxe...

Abstract

The invention applies to the technical field of information processing, and provides a radiotherapy treatment plan displaying method and system. The method comprises the steps of receiving a first two-dimensional dose image sequence; sequentially storing dose values corresponding all voxel volumes in the first two-dimensional dose image sequence so as to obtain three-dimensional dose volume; receiving a CT image sequence; performing two-dimensional sampling for the three-dimensional dose volume through the CT image sequence so as to obtain a second two-dimensional dose image sequence; determining a DVH (Dose Volume Histogram) of the structure according to the second two-dimensional dose image sequence; generating binary communication area image sequence according to the second two-dimensional dose image sequence; generating an equal dose curve according to the binary communication area image sequence; generating and displaying an equal dose curve displaying scene and a DVH curve display scene according to the CT image sequence, the equal dose curve and the DVH of the structure. With the adoption of the method and the system, the equal dose curve display scene and the DVH curve display scene can be directly displayed.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a radiotherapy plan presentation method and system. Background technique [0002] In the field of tumor radiation therapy, before tumor patients receive radiation therapy, radiologists will simulate positioning images based on computer tomography (CT) scans of tumor patients to outline the structural outline of the patient's tumor and the tumor involved in radiation exposure. Structural outlines of nearby organs. The radiotherapy physicist then designs a treatment plan on the treatment planning system (TPS) for radiotherapy on the patient's tumor site on the radiotherapy equipment based on the structural outline drawn by the radiologist and the CT simulation positioning image. The radiotherapy plan design After completion, the radiation oncologist needs to present the radiation treatment plan to confirm whether the plan is suitable for treating the pat...
