An image change detection system for observing an environment to be monitored, such as a region proximate a vehicle, by sensing energy from the region and generating a plurality of pixels which form an image of the region. The system stores a first image of the region and matches pixels of a subsequent image of the region with pixels of the first image to detect deviations between corresponding pixels. The system indicates when the pixel deviations exceed a preselected threshold to detect an abnormal condition in the region. Also a method of monitoring the environment about a vehicle by sensing a first image, sensing a subsequent image, matching the pixels of the subsequent image with the pixels of the first image to detect deviations between corresponding pixels, and indicating when pixel deviations exceed a preselected threshold.

Image change detection system

A microwave dipole probe for in vivo localized hyperthermia includes an outer conductor and an inner conductor extending through and beyond the outer conductor. The portion of the inner conductor extending beyond the outer conductor is expanded in diameter relative to the portion within the outer conductor. A dielectrically loaded phase reversal sleeve is folded over the outside of the outer conductor and contains a dielectric loading material similar to the dielectric constant of the in vivo target volume.
