We are developing videotactile fingertip sensors which will enable people to interact with the visible world via their fingertips.
|In-Situ Image Guidance for Microsurgery
We have developed a new image-based guidance system for microsurgery using optical coherence tomography (OCT), which presents a continuously updated virtual image in its correct location inside the scanned tissue. OCT provides real-time, 6-micron resolution images at video rates within a 2-6 mm axial range in soft or transparent tissue, and is therefore suitable for guidance to various targets in the eye. Ophthalmologic applications in general are diverse within the realm of anterior-segment surgery, whether for medical treatment or for scientific experimentation. Surgical manipulations, especially of the cornea, limbus, and lens may eventually be aided or enabled, and as an example we are presently working to guide access to Schlemm’s canal for treating Glaucoma.
We are using video cameras to give vision to the ultrasound transducer. This could eventually lead to automated analysis of the ultrasound data within its anatomical context, as derived from an ultrasound probe with its own visual input about the patient’s exterior. We are exploring both probe-mounted cameras, as well as optically-tracked stand-alone cameras which could view a larger portion of the patient's exterior.
We are developing a method of medical visualization that merges real time ultrasound images with direct human vision.
