ART Advanced Research Technologies is Granted Key Patent for Imaging of Breast Physiology

Thursday, November 01, 2007

New U.S. patent for optimal selection of SoftScan® optical wavelengths strengthens patent portfolio

Montreal, Canada -- ART Advanced Research Technologies Inc. ("ART") (TSX:ARA), a Canadian medical device company and a leader in optical molecular imaging products for the healthcare and pharmaceutical industries, is pleased to announce that the United States Patent and Trademark Office has issued to ART patent number 7,286,869 entitled "Choice of wavelengths for multi-wavelength optical imaging". The use of this method within an optical medical imaging device allows significant improvement in the recovery of precise images of the physiological components. These components are used to provide indications for diagnosis and treatment monitoring of cancer in the ART SoftScan® optical breast imaging system.

"Our already extensive IP portfolio is being further enhanced with such an important patent, which is key in retaining our technological leadership in the optical imaging industry segment," said Sebastien Gignac, ART's President and CEO.

The present invention provides an objective method for choosing the wavelengths for a multi-wavelength TPSF or CW-based optical imaging system. The patent also allows for the optimization of other parameters of the system other than wavelengths and can be applied to optical absorption spectroscopy in general.

About the SoftScan® system

The SoftScan® optical breast imaging system has been designed first as a complementary diagnostic tool to mammography, with ultimate uses in the detection and treatment monitoring of breast cancer. Its non-invasive, painless approach uses time-domain optical imaging technology, which may allow clinicians to better locate and characterize breast tumors as benign or malignant and could provide faster assessment of therapeutic effectiveness. Unlike mammography whose use must be strictly limited, the SoftScan system emits no radiation and can be safely used as often as needed to monitor patients. The device was created and developed by ART Advanced Research Technologies Inc., and has obtained regulatory approvals for its commercialization in Canada and in Europe.
