("ART") (TSX: ARA), a Canadian medical device company and a leader in optical molecular imaging products for the healthcare and pharmaceutical industries, will be exhibiting at the Annual Meeting of the American Association for Cancer Research (AACR), April 19-22, in Denver, Colorado. ART will showcase its preclinical product offering, including current research in oncology and related fields using the Optix� optical imaging device, as well as the Fenestra� line of contrast agents for microCT imaging, at its booth (#757) located in the Colorado Convention Center.

The Annual Meeting of the American Association for Cancer Research (AACR) is the world's largest and most comprehensive gathering of professionals in the cancer field, encompassing basic, translational, and clinical research. This prestigious annual event highlights the latest developments in cancer research and is attended by over 17,000 delegates from universities, research institutions and the pharmaceutical industry.

About the Optix� system

Based on time-domain technology, which allows measurement of the light's time of arrival, the Optix� in vivo optical molecular imaging device is the most sensitive optical imager commercially available on the preclinical market, allowing for detection of lower concentrations of signals deeper inside the body. Unique to the Optix system is the ability to recover fluorescence lifetime, which can be used to separate and quantify probe distributions depending on their respective biochemical environment. Also part of the Optix product offering is a CT fusion software package allowing researchers to export the scan obtained using Optix in DICOM format, and fuse it with microCT for a full 3D anatomical reference.
