Audible feedback from positional guidance systems

摘要: A computer based system (200) generating audible feedback (260) to assist with guidance of at least one trackable point in space is provided. Surgical embodiments include (to supplement visual and tactile feedback) a surgeon moving the tip (235) probe (230), for example, surgical field respect volume interest such as tumor (100). Other precise insertion pedicle screw. In embodiments, moves or instrument (230) within field, analyzes current position and/or fiducial markers (240, 242, 244, 246). The then provides predetermined feature(s) (such (100)) previously identified on reconstruction view obtained, by magnetic resonance imaging (MRI) scan, computerized tomography (CT) scan an ultrasound scan. may vary numerous ways, tone, volume, pattern style, relative interest.
