Title:
RACK STRUCTURE AND RADIOTHERAPY EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2019/091269
Kind Code:
A1
Abstract:
Provided are a rack structure and a piece of radiotherapy equipment, belonging to the field of radiotherapy equipment. The rack structure comprises: a rotatable rack (1), and a therapy head (3) which is arranged on the rotatable rack (1) and can swing in an axial direction of the rotatable rack (1). The rack structure further comprises: an anti-collision detection mechanism (4) arranged on the rotatable rack (1) and located below the therapy head (3). The anti-collision detection mechanism (4) is used for forming multiple signal links that can be physically blocked; the multiple signal links are arranged along a swing trajectory of the therapy head (3) in the axial direction of the rotatable rack (1); and each of the signal links extends in a direction perpendicular to the axial direction of the rotatable rack (1) so as to cover the therapy head (3). Anti-collision detection can be performed by detecting whether a signal link is physically blocked.
