Toshiba America Medical Systems Inc. (TAMS) and Vital Images Inc. are collaborating with cardiologists at the Johns Hopkins University School of Medicine to develop applications for high-resolution, multislice coronary computed tomography angiography (CTA) imaging.

The partnership has resulted in the further development of coronary CTA imaging applications using TAMS' Aquilion 16 CFX and Aquilion 32 CFX multislice CT scanners with Vital Images' Vitrea 2 visualization and analysis imaging software. The new applications enable cardiologists to obtain a better image of the heart and cross-examine the coronary arteries for abnormalities and blockage.

The past difficulty for coronary CTA imaging has been managing the vast volumetric data generated by a multislice CT system. One key development of the collaboration is the patented angio-emulation technology for the Vitrea 2 imaging software for acquiring coronary CTA images using both the Aquilion 16 CFX and Aquilion 32 CFX systems.

The application enables cardiologists to unravel the images of coronary arteries into two planes, seeing the arteries in the context of the entire heart and making cross-sectional measurements that allow the user to acquire a more accurate stenosis measurements.
