摘要：A surgical navigation system and method for identifying positions on a patient,

including a processor, and a tracking system for tracking a pointer tool. The processor isprogrammed to initialize a surface trace acquisition, continuously record the positions ofthe pointer tool during the surface, conduct trace acquisition, combine the positionsrecorded during the surface trace acquisition into a surface trace, receive a patient imageof the patient, extract a surface from the patient image, compute a registration

transform between the surface traces and the surface for patient registration, segmentthe patient image into a regions where each region contains an anatomical landmark,determine a spatial distribution of surface traces among the regions; determine whetherthe spatial distribution in relation to each region minimizes deviance below a threshold,and if the determination is exceeding the threshold, provide information relating to suchregion.
