It is aligned with equipment rotation center, i.e., Radiation Center is overlapped always with rotation center, which is commonly referred to as isocenter point.The feature
It is required that equipment is in clinical use, it is necessary to ensure that tumour is at isocenter point always.When the equal centers of tumor target and equipment
When point is equipped with deviation, tumor target can not be just illuminated, and you can't get enough dosage.2, due to it is different in patient body
Knub position is different, and tumour is not and to be possible in body one in central location in patient body in most cases
Side.Due to needing that tumour is placed at isocenter point, that is, need by patient toward equipment side deviate, this requires equipment have compared with
Big treatment space, biggish radius of turn.After the radius of turn of equipment increases, it can to treat precision reduction.3, due to penetrating
The dosage rate of line and irradiation distance are at the relationship of inverse square, and after the radius of turn of equipment increases, the dosage rate of equipment also can be with
Reduce rapidly, this causes clinical treatment efficiency also to reduce.4, but past since patient is not often to entreat position in a device
The offset of equipment side causes when rack rotates or Mobile treatment table carries out noncoplanar irradiation treatment, and there are racks and treatment
The risk of bed (or patient) collision.
Summary of the invention
