摘要：
In a method and magnetic resonance (MR) apparatus for implementing an MR-guided procedure, an MR-compatible digital camera is placed in the patient receiving opening of the MR data acquisition unit that is operated to acquire MR data for reconstructing images that are used to guide the MR-guided intervention. The digital camera is operated to obtain digital images of the exterior of the patient, from which motion of the patient is detectable. The images are analyzed in a processor to identify therefrom the motion of the patient and the result of the analysis is represented as a processor output that is used to control the timing, with respect to the motion of the examination subject, of the occurrence of at least one event in the MR-guided procedure. One important application is respiratory gating/triggering of HIFU sonication for the treatment of moving organs.
