Abstract
A detector unit (20) for an image guided surgery system (10) is provided. It includes an adjustable stand (22) having a plurality of receivers (24) mounted thereto such that the detector unit (20) has a predefined finite field of view (80) in which it detects radiant energy. It further includes at least one light source (90) mounted to the adjustable stand (22) in fixed relation to the receivers (24). The at least one light source (90) projects visible light in a predetermined pattern to mark a location of the field of view (80).
Claims21
A detector unit for an image guided surgery system comprising:
- an adjustable stand;
- a plurality of receivers mounted to the adjustable stand such that the detector unit has a finite defined field of view in which it detects radiant energy;
- and,
- at least one source of radiant energy mounted to the adjustable stand in fixed relation to the receivers,, said source projecting radiant energy in a pattern to mark a location of the defined field of view.
A method of positioning a finite field of view of a detector unit for an image guided surgery system, the method comprising:
- (a) holding a surface at a point in space;
- (b) projecting a pattern of light from the detector unit toward the surface, said pattern of light having a fixed spatial relationship with respect to the detector unit's field of view;
- (c) viewing the surface;
- and,
- (d) adjusting the detector unit and surface relative to one another until a desired pattern of light is viewed on the surface.
A field of view targeting system for an image guided surgery system having a detector unit which tracks the orientation and position of surgical tools within a defined field of view, said field of view targeting system comprising:
- a plurality of sources which project a pattern of radiant energy, said pattern of radiant energy being spatially fixed relative to the defined field of view.
