Treatment is adapted with the fixing glue of modified form thermoplastic nethike embrane, can firmly fix thermoplastic nethike embrane.The design coordinates modified form
The fixation of thermoplastic nethike embrane can ensure that patient is relatively fixed in the longitudinal direction, and displacement error range is small.
4, the utility model is used for radiotherapy, can also make on CT machines, magnetic resonance, linear accelerator and attached CBCT
With, and the utility model has certain distance apart from tumor locus, and not in scanning range, design, agent to target area treatment plan
Amount, which calculates, influences very little；The lithotomy position Postural immobilization that can be used for perineum superficial tumor radiotherapy, as carcinoma of vulva, cancer of anal margin and
Inguinal lymph tumor etc..
5, it is basis that tumour radiotherapy, which is accurately positioned, and mechanical positioner is the core for ensureing treatment accuracy, this reality
It with novel be fixedly connected into integrated structure with treatment bed body and had the advantages that accurate positioning, while use is detachably installed
Structure design is relatively fixed preferable coordinate basis and carrier when being precise radiotherapy with patient.
6, the utility model makes patient around, the movement in head foot direction is effectively controlled, easy to operate, pendulum
Position error is small, and position is reproducible.Its is small, light-weight and few to the attenuation of X-ray, to patient in terms of dosage
Calculating can be ignored, and can be placed on conventional fixation bottom plate, not need any equipment of extra purchase, economic benefit
It is good.
