摘要： The present invention relates to a collision detecting device for a radiation treatment apparatus, comprising a radiation unit having an internal space, for directing radiation beams towards a radiological focus in the internal space for treatment of a target in a patient's body therein. The collision detecting device comprises a collision detecting unit being electrically conductive at least on its outer surface and having a size slightly smaller than the internal space of the radiation unit, so as to be insertable into the internal space and held in an electrically insulating manner in respect of the radiation unit by spacer elements. The outer electrically conductive surface is connectible to an electrical voltage supply in order to detect if the outer surface of the collision detecting unit abuts against the inside surface of the radiation unit. The invention also relates to a method for performing such collision detection.
