JMAR Installs Computer Aided Microscope at the University of Vermont College of Medicine; New Optical Microscope Enables Fast Scanning and Digital Image Analysis of Biomedical and Material Samples

SAN DIEGO--(BUSINESS WIRE)--June 23, 2005--JMAR Technologies, Inc. (Nasdaq: JMAR) has installed a Beta model of its new Scanning Computer Aided Microscopy (CAM) system at the Microscopy Imaging Center in the College of Medicine at the University of Vermont to evaluate its applications in thick tissue pathology research and studies of whole animal models.

JMAR's new Scanning CAM system, based on JMAR's scanning boom (Patent Pending) technology, provides an open viewing area to accommodate large or thick samples. Software developed by JMAR converts the high-magnification scanned images into a low magnification mosaic for viewing at the macro scale with the ability to zoom into areas of interest at high magnification. Computer Aided Microscopy controls allow the operator to dynamically vary the magnification, while selecting any area of interest in the displayed mosaic image at magnifications up to 3100X.

“This system addresses advanced microscopy requirements over a wide range of applications in many research and industrial settings.”

The Scanning CAM represents a major departure from conventional microscopy systems in that it can perform detailed software analysis of scanned imagery from samples that would not fit into a typical microscope. The new all-digital system integrates the capabilities of several types of specialty microscopes, enabling it to meet a broad range of applications including well-plate bio-assays, library-based image searches of pathology samples or whole animal models, analysis of material samples such as powders or metals, failure analysis of materials or structures, and forensic studies of large non-planar samples.

"This unique system will allow institutions or organizations with limited funds or laboratory space to purchase a single instrument that will allow them to conduct high quality research or educational studies without the requirements for multiple, specialty microscopes," commented Scott McLeod, the Project Manager and inventor of the scanning boom system. "This system addresses advanced microscopy requirements over a wide range of applications in many research and industrial settings."

More than 300 researchers currently utilize UVM's Center for Microscopy where the Scanning CAM will initially be evaluated for tissue pathology applications. In addition to its primary evaluation, other departments will be invited to evaluate the system for use in metallurgy, material science, chemistry, biology, bio-paleontology, geology, forensics, and failure analysis.

The system, previously referred to as the Oasis Project, is expected to be available to the general market later this year.

About the Scanning CAM System

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.
