A positioning device for the distal extremities in radiotherapy

Abstract

A positioning device for the distal extremities for radiotherapy, comprising a holding position (100) and a portal positioning frame (200), characterized in that: The aforementioned portal positioning frame (200) has a horizontal positioning point (210) on its upper side and two vertical positioning points (220) extending downwards from both ends of the horizontal positioning point (210); the lower ends of the two vertical positioning points (220) are attached to the suspension side (100) in an adjustable position. A first guide rail (211) is attached to the lateral positioning device (210) along its longitudinal direction; a first sliding block (212) is slidably mounted on this guide rail, and a first infrared emitter (213) is attached to this sliding block.Each of the aforementioned vertical positioning parts (220) has a second guide rail (221) attached, which runs in the vertical direction; a second sliding block (222) is suspended on this rail, to which a second infrared-emitting transmitter (223) is attached.
