[A novel mechanical orientation system used for body precise radiotherapy].
In the end of last century, there was a leap in the technological quality of radiotherapy, which is incarnated in three new technologies: Stereotactic radiation surgery (SRS), three-dimensional conformal radiation therapy (3D-CRT) and intensity modulated radiation therapy (IMRT). However, the achievement of these technologies has a close relationship with the precise orientation of tumour. Especially, in terms of body stereotactic precise radiation therapy, its body mechanical orientation system is the kernel to guarantee the accuracy of radiotherapy. This paper presents a novel mechanical orientation system for body precise radiotherapy. It is characterized by flexible adjustment, deft removal, easy disassembly and accurate orientation using apart structure to substitute old integer structure and adopting single segment Z shape orientation marker staff. The new mechanical orientation system guarantees the effect of tumour radiotherapy, which is worthy to be recommended for clinical use.
