Embodiment Construction
[0084] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0085] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0086] Since the dynamic intensity modulation of conformal intensity-modulated radiation therapy (IMRT) is that the blades of the multi-leaf collimator are in a moving state when the beam is emitted, the corresponding shape is formed by controlling the relative position and residence time of each pair of blades of the multi-leaf co...
