Less detector can be used under the drive of the drive in this way, move to the radiation beam that first position receives the first ray head, move to the radiation beam that the second position receives the second ray head, the radiation beam that other positions receive other ray heads can certainly be moved to, to realize the functions such as dosage verifying or image guidance using less detector in therapeutic equipment, a large amount for the treatment of space is saved, while less detector can also substantially reduce the acquisition cost and maintenance of therapeutic equipment
Cost.
It is exemplary, method further include: the first locking device is adjusted, so that the relatively described exercise stress movement of sliding part.It can be thus adjusted when needing to adjust sliding part according to sliding part and the mated condition in sliding rail portion, be adapted to different slide rails.
It is exemplary, the method also includes: driving structure drives the detector on exercise stress along the axial movement of roller.Thus the position of detector can be adjusted in the axial direction according to the position of ray, so that detector be allowed more accurately to receive ray.
It is exemplary, the method also includes: movement mechanism drives the exercise stress along the radial motion of roller, to increase or reduce the distance of the exercise stress to the centre of the drum.The distance of exercise stress to centre of the drum can be thus increased or reduced, so as to adjust the size of beam on the detector.
Exemplary, the first ray head and the second ray head are MV grades for the treatment of heads.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, without departing from the inventive concept of the premise, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to protection scope of the present invention.
