SAN DIEGO--(BUSINESS WIRE)--Oct. 24, 2005-- JMAR Technologies, Inc. (Nasdaq: JMAR) and the University of Vermont have completed initial test and evaluation of JMAR's VersaCAM scanning boom microscopy system at UVM's Microscopy Imaging Center in the College of Medicine. The system, installed at the University in June of 2005, has been available to numerous researchers and clinical pathologists for the purpose of thick tissue pathology research and studies of whole animal models.

Researchers used the VersaCAM system to scan large areas of slides containing various types of tissues and cells. Of particular interest to UVM researchers were the high magnification, large area images of whole mouse aorta cross-sections and large sections of mouse lung tissue that have been exposed to high levels of asbestos. These samples were evaluated for changes in epithelial tissue and collagen buildup as a result of asbestos exposure. Software developed by JMAR converts high-magnification scans of these samples into a low magnification, large area mosaic for viewing at the macro scale, yet enables the viewer to zoom into areas of interest at magnifications up to 3,100X.

In addition to use in tissue pathology, other departments at the University were invited to evaluate VersaCAM in diverse applications including metallurgy, material science, chemistry, biology, bio-paleontology, geology, forensics, and failure analysis. Dr. Doug Taatjes, Directing Professor of the UVM College of Medicine Microscopy Imaging Center, commented, "The versatility of the system is its strongest asset in a multi-user microscopy imaging center. For instance, in the Microscopy Imaging Center in the University of Vermont, our clients range from biomedical researchers to materials and physical scientists. Sample preparations will vary widely, with not all specimens able to be placed onto a glass slide and mounted on a microscope stage. Thus the ability to swing the boom arm out and image a bulk specimen is a particularly attractive feature of the system. I am also impressed by the speed and accuracy of the scanning, along with the image stitching algorithm."

Ronald A. Walrod, President and CEO of JMAR said, "We appreciate UVM's interest in the VersaCAM system. Their constructive feedback supports our belief that this innovative microscope will come to be regarded as an important tool for life science, medical, and materials research. We are currently enhancing the microscope functionality by adding a fluorescence capability in the visible and near infrared spectrums with a low light capability for bioluminescence research in whole animal models." Mr. Walrod continued, "We also plan to provide a VersaCAM with the fluorescence option to researchers at the University of Connecticut later this year to image green and red fluorescence proteins used in the study of cancer intervention therapies in chicken embryos and whole animals. They will evaluate the system's ability to measure very small changes in cancer tissue volumes."

About VersaCAM

JMAR's Scanning CAM is a fast-scanning digital image analysis microscopy system able to auto focus from starting distances of over fourteen inches down to focus positions controlled in nanometer increments allowing confocal imagery of samples. Its unique design provides an unobstructed viewing area to encompass large samples or whole animal models. The microscope can be rotated to view large adjacent static samples of any size. This flexible geometry, combined with the ability to rotate the objective lens 360 degrees, enables high magnification scanning and digital image analysis of samples in the normal, inverted, or side viewing positions. The Scanning CAM system is sized and configured for easy transport between laboratories or use in remote field locations. Numerous applications exist in the fields of material science, tissue pathology, metallurgy, chemistry, biology, bio-paleontology, geology, forensics, and failure analysis.
