A Method for Checking the Alignment Status of the Stereotactic Frame in Cerebral Angiography for Radiosurgery

摘要

is an object of the present invention to a patient when taking a picture in order to minimize errors in the image obtained through angiography device is easy to determine the alignment of the stereotactic frame is mounted to provide a stereotactic frame alignment verification method of angiography device to enable precise alignment of the stereotactic frame based on it . ; in the present invention has a front and rear further comprising fixing the stereotactic frame , each reference point is displayed in a particular region of a specimen ; Preliminary steps for shooting a reference point display surface of the stereotactic frame before the shooting ; In contrast to the photographed image of the two surfaces provides a stereotactic frame alignment of the front and angiography apparatus to determine whether the match corresponding to the respective reference point comprises a step , such as to align the position of the stereotactic frame in the back .
