Projection Scanning System

Abstract

Imaging systems projecting augmented information on a physical object that at a minimum include a processor, a memory device operably connected to the processor, a projector operably coupled to the processor, and a distance-measuring device operably connected to the processor. The memory device stores augmented image information, and the processor is configured to project augmented image information onto the physical object. The distance-measuring device is configured to measure the distance to the physical object. The processor uses distance measurement information from the distance measuring device to adjust scaling of the augmented image information. The processor provides the scale adjusted augmented image information to the projector. System can also be used for fluorescence imaging during open surgery, for endoscopic fluorescence imaging and for registration of surgical instruments.

What is claimed is: 
     
         1 . An imaging system projecting augmented information on a physical object, the imaging system comprising:
 a processor;   a memory device operably connected to the processor, the memory device storing augmented image information;   a projector operably coupled to the processor, the processor configured to project augmented image information onto the physical object; and   a distance-measuring device operably connected to the processor and configured to measure the distance to the physical object,   the processor using distance measurement information from the distance measuring device to adjust scaling of the augmented image information, the processor providing the scale adjusted augmented image information to the projector.
