一种新型放疗定位床的设计

Design of a New Type of Radiotherapy Bed

本文设计了一种新型的放疗定位床。在床的头部、体部位置分别布局双N形定位标志杆,采用铅芯作为标志材料,并设计了固定槽、长方形头枕槽、半圆卡、体膜压板、水平固定板、弓形尺等;同时采用先进的具有记忆功能的体膜/面膜做固定。既用一套定位装置实现了全身定位,同时还解决了头颈部位难以固定、定位及复位的问题,弥补了现有的CT(ComputedTomography)定位系统都无法使用一种定位装置实现全身定位的许多不足。

Designs a new type of radiotherapy bed, layouts the double-N-shaped mark pole in the head and body positions and the use of pencil core as a sign material and design a fixed slot, rectangular head slot, half cards, Membrane clips, the level of fixed panels, and arch-foot, while using advanced body membrane/surface membrane with a memory function for fixing, so as to solve the problem that it is difficult to fix the head and neck site and reset the positioning.
