Guardian Technologies to Demonstrate 3i Signature Mapping™ Technology at RSNA 2006

Signature Mapping™ Represents the Application of Guardian’s Threat Detection Technology Applied to Healthcare Imaging

RSNA 2006
HERNDON, Va.--(BUSINESS WIRE)--Guardian Technologies International, Inc. (OTCBB:GDTI), a leading technology developer of intelligent imaging informatics (3i) solutions, today announced that it has successfully applied Guardian’s core digital imaging detection technology to medical images. “Our initial clinical results have clearly demonstrated that the application of our patented imaging analytics technology used for the detection of explosives, when applied to the analysis of medical images, will dramatically improve the diagnostic characteristics of digital medical images. We believe these advancements will result in improved and speedier diagnoses, and greater workflow efficiency for the diagnosing physician,” stated Guardian’s Vice President of Business Development, Richard Borrelli.

Guardian will demonstrate this innovative technology during the Radiology Society of North America (RSNA) conference held in Chicago in late November. RSNA provides the ideal platform for the introduction of this new technological breakthrough. RSNA is the largest radiographic conference in the world with an attendance of over 60,000 medical professionals, scientists and administrators. Guardian’s advanced research team has scheduled meetings with and will present to a prominent group of physicists, radiologists, researchers and practitioners from leading corporations and research universities in the healthcare imaging field.

Guardian will be demonstrating its clinical work with Signature Mapping™, a technology initially developed for threat detection, and currently under technical and scientific evaluation by governmental testing agencies in the United States and Russia. Signature Mapping™ is a unique methodology and algorithmic process that creates distinctive signature maps for organic or inorganic targeted materials. Signature Mapping™ is an adaptive, reaction-based analytical process whereby each image responds to applied algorithms. The resulting image signature map is then evaluated against a known library of targeted signature maps for the purpose of identification and characterization. The algorithmic process, built on machine learning platforms, can analyze and identify thousands of signature maps in real time.

Signature Mapping™ clinical results were derived from five pilot studies which have been conducted in a collaborative research and development effort with the Image Processing and Informatics Laboratory (IPI), University of Southern California (USC). The wide ranging clinical research includes detection and quantification of multiple sclerosis lesions; normal pressure hydrocephalus; acute intracranial hemorrhage; tuberculosis; and, the quantification, tracking, clarification, and detection in dense breast tissue.
