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 be enclosed in a sterile container (e.g., a probe bag) and a mirror and mirror housing may be separately attachable to the image capture device and display. In these embodiments, the mirror may be disposable and the sterility of the overall imaging device is maintained.
