titleOfInvention | radiotherapy equipment, storage medium, and method and device for generating subfield shape |
abstract | The embodiment of the invention discloses radiotherapy equipment, a storage medium, a subfield shape generating method and a device. The treatment device comprises: the treatment head, the controller and the multi-blade collimator; the treatment head comprises a radiation source for generating a radiation beam; the multi-leaf collimator comprises a plurality of leaves; the controller is used for executing the following operations: obtaining a current contribution matrix according to the current dose distribution and the ideal dose distribution; determining an initial sub-field shape according to the current contribution matrix; adjusting the initial sub-field shape according to a preset adjustment target to generate a target sub-field shape; and controlling the movement of the plurality of leaves of the multi-leaf collimator according to the determined target sub-field shape to form the target sub-field shape. By the technical scheme, the sub-field shape with more controllable shape regularity is generated, so that the multi-leaf collimator can accurately form the target sub-field shape, and the controller can further accurately control the dose of the target sub-field. |
