Abstract: A multispectral synchronized imaging system is provided. A multispectral light source of the system includes: blue, green and red LEDs, and one or more non-visible light sources, each being independently addressable and configured to emit, in a sequence: at least visible white light, and non-visible light in one or more given non-visible frequency ranges. The system further includes a camera and an optical filter arranged to filter light received at the camera, by: transmitting visible light from the LEDs; filter out non-visible light from the non-visible light sources; and otherwise transmit excited light emitted by a tissue sample excited by non-visible light. Images acquired by the camera are output to a display device. A control unit synchronizes acquisition of respective images at the camera for each of blue light, green light, visible white light, and excited light received at the camera, as reflected by the tissue sample.

Abstract: Described are various embodiments of a sensored surgical tool, and surgical intraoperative tracking and imaging system incorporating same. In one embodiment, the surgical tool comprises a rigid elongate tool body having a substantially rigid tool tip to be displaced and tracked within the surgical cavity so to reproducibly locate the tool tip within the cavity. The tool further comprises one or more tool tip cameras and/or pressure sensors operatively disposed along the body at or proximal to the tool tip.
