In 2015, Shimadzu released the Minimally invasive eXperience (MiX) package for its Trinias series of floor and ceiling angiography systems, with software applications designed to support minimally invasive procedures. Part of a 2016 upgrade for the package is SCORE PRO Advance, a radiation dose-reduction technology that still allows for high-quality radiographic and fluoroscopic images. The company also released a new function called TraceMAP, which traces the contours of blood vessels from the digital subtraction angiography (DSA) image, which can be used as a road map image overlaid on live fluoroscopy.
The upgrade also includes Navi+Plus, which allows the ability to integrate pre-procedure CT images into fluoroscopy, though users need to have the optional 3-D application for the Trinias series, says Frank Serrao, marketing manager for Shimadzu. For the SCORE StentView+Plus application, which displays stent placement in real time, Shimadzu introduced the ability to view two regions of interest at a time. "[This] is useful for cases in which you’re placing two stents that are not close to each other and in different regions of interest,” Serrao says.

In November, just in time for the annual meeting of the Radiological Society of North America in Chicago, Siemens Healthineers received FDA clearance for two new features as part of its PURE platform — syngo CTO Guidance and syngo EVAR Guidance — for use on the Artis zee, Artis Q and Artis Q.zen angiography systems. Anthony Medigo, vice president of cardiovascular solutions at Siemens Healthineers, says syngo CTO Guidance advances the treatment of challenging chronic total occlusions (CTOs), a complete blockage of a coronary artery. The syngo CTO Guidance feature utilizes CT angiography (CTA) and can visualize the entire artery, even the blocked-off section, which can’t be visualized with contrast. This CTA can be fused with the angio system to overlay the exact line of the vessel.
“Patients are coming in older, sicker, and the disease progression is much worse,” Medigo says. “Something like this gives physicians additional tools to treat this complex patient.” For endovascular aneurysm repair (EVAR), syngo EVAR Guidance automatically detects vessel walls on a CT scan and places landmarks, also directing the angle of the C-arm to make the procedures more precise, according to the company.
Also at RSNA, Siemens unveiled its Artis pheno robotic angiography system, which allows for faster 3-D image acquisition than its predecessor, the Artis zeego. To accommodate larger patients, the Artis pheno possesses a C-arm with a free inner diameter of 95.5 centimeters — 13 centimeters wider than its predecessor. The system also has a table that can accommodate patients weighing up to 617 pounds. The Artis pheno is pending 510(k) clearance from the FDA.
