Siemens Healthcare unveiled its new x-ray tube and detector technology for its Artis Q and Artis Q.zen angiography systems.

Designed to improve minimally invasive therapy of diseases such as coronary artery disease, stroke, and cancer, the new x-ray tube in both the Artis Q and Artis Q.zen series can aid physicians in identifying small vessels up to 70% better than conventional x-ray tube technology, according to Siemens. The Artis Q.zen combines this x-ray source with a new detector technology designed to support interventional imaging in ultra-low-dose ranges to patients, physicians, and medical staff.

The company stated the second generation of its flat emitter technology is key to the advances made in the x-ray tube for the Artis Q and Artis Q.zen product lines. Instead of the coiled filaments used in conventional x-ray tubes, flat emitter technology is used exclusively in the new tube to emit electrons. Flat emitters are designed to enable smaller quadratic focal spots that lead to improved visibility of small vessels.
