Abstract

A device for combining tomographic images with human vision using a half-silvered mirror to merge the visual outer surface of an object (or a robotic mock effector) with a simultaneous reflection of a tomographic image from the interior of the object. The device maybe used with various types of image modalities including ultrasound, CT, and MRI. The image capture device and the display may or may not be fixed to the semi-transparent mirror. If not fixed, the imaging device may provide a compensation device that adjusts the reflection of the displayed ultrasound on the half-silvered mirror to account for any change in the image capture device orientation or location.
