Embodiment 1
[0081] An online radiotherapy planning quality control system, the system includes: a data input and output module, an adaptive planning module, and an online sketch modification tool.
[0082] The methods required by the online radiotherapy planning quality control system include: an image deformation registration method, an online adjustment method, and a dose calculation method.
[0083] in,
[0084] The data input and output module is responsible for external communication of the system.
[0085] The online delineation modification tool can perform online modification to the online target area and the outline of the organ at risk.
[0086] Further, an online radiotherapy planning quality control method, the method includes the following steps:
[0087] 1) The data input and output module obtains the original radiotherapy plan, original outline, and original image;
[0088] in,
[0089] The original radiotherapy plan, original delineation and original image may be the i...
Embodiment 2
[0103] On the basis of Example 1, in order to further improve the degree of automation of the online radiotherapy planning quality control system and further save doctors' labor, this example further improves the adaptability of the system, and the similarities with Example 1 will not be repeated, as follows .
[0104] An online radiotherapy plan quality control system, the system includes: plan evaluation index limit value template setting module, data input and output module, radiotherapy plan evaluation index limit value setting module, self-adaptive plan module, online outline modification tool.
[0105] The methods required by the online radiotherapy plan quality control system include: image deformation registration methods, online adjustment methods, dose calculation methods, and online evaluation methods.
[0106] in,
[0107] The plan evaluation index limit template setting module is used to set the plan evaluation index limit template, and the plan evaluation index ...
Embodiment 3
[0120] On the basis of Embodiments 1 and 2, this embodiment further defines the online plan correction method.
[0121] The online plan modification method specifically includes:
[0122] (1) Image registration is performed on the online image and the original image to generate a corresponding three-dimensional deformation vector field;
[0123] (2) According to the three-dimensional deformation vector field, the online image is generated as a fusion image with the same coverage as the original image and an online outline describing the outline of the target area and organs;
[0124] (3) Determine the two-dimensional deformation vector field of the ray intensity in each beam direction in the original radiotherapy plan according to the three-dimensional deformation vector field in the set region of interest; wherein,
[0125] The region of interest usually refers to the target region, and may also include important organs at risk. The set ROI means that the user can designate...
