Abstract: System and method for periodic body scan differencing for detecting changes in surface and subsurface body scans over time. May include use of a scanner and a computer system configured to scan a portion of body at first point in time to yield first scan, scan the portion of the body at second point in time to yield second scan, difference the two scans to produce a morphological difference image, and display the morphological difference image. May utilize surface or subsurface scans. Any type of scanner may be utilized that scans to the desired resolution of morphological testing. Can morph scan(s), geometrically, visually or both, to account for age, weight or color differences that have occurred between scans. Can display morphological surface or subsurface differences between scans in multiple images or atlas view. Differences can be displayed independently or overlaid onto scan(s). Differences may be highlighted to make more readily viewable.

Abstract: Enables a measurement catheter configured to hold a package such as an optical tomographic module and/or blood flow velocity module. May hold any package reduced to a size small enough to fit in a blood vessel. Example packages include an optical transmitter and receiver/detectors that enable internal optical tomographic images of vessels to be captured, for example without rotation of the catheter in the vessel. Alternatively or in combination, a thermal package may be coupled to the measurement catheter that includes a thermal element and detector(s) that enable blood flow velocity to be accurately internally measured that does not require a static catheter position. In addition, the measurement catheter may optionally attach to an interchangeable coupler that allows for the introduction of substitution of packages or any type of catheter end assembly to provide rapid deployment of additional surgical or sensory elements.

Abstract: A storage system based on the propagation delay of light is disclosed which utilizes an array of fiber optics to store the information. The storage device is configured as two loops. Data is injected from one loop and data is continuously recirculated for storage in the other loop. A pulsed laser provides the clocked energy source and is split for use, both, in recirculating the data, and for new data injection. Multiple channels of light are extracted by using a diffraction grating. The source may be interrupted to erase data in the recirculating memory. Recirculation takes place over a single strand fiber optics coil of any length. Multiple frequency encoded channels of data are multiplexed into the single strand of fiber optic with an integrating lens and the channels are decoupled on the other end with a diffraction grating. To prevent compounding signal degradation, optical switches are used to regenerate the signal at each pass through the loop.
