GE Healthcare announces the First Installation of Alcyone Technology

An announcement was made by GE Healthcare on Tuesday, regarding the first installations of its new cadmium zinc telluride (CZT) based SPECT/CT nuclear cardiology camera featuring Alcyone Technology, the Discovery NM/CT 570c. This revolutionary imaging system has been installed at Rambam Medical Center in Haifa, Israel and University Hospital in Zurich, Switzerland. Features of the Discovery NM/CT 570c include the high-speed, high-resolution capabilities of GE’s LightSpeed VCT in conjunction with the groundbreaking Alcyone technology. This remarkable system ushers in the first generation of volume SPECT/CT technology, making it possible to carry out new procedures in non-invasive cardiac imaging beyond those offered by conventional SPECT or SPECT/CT scanners. It is possible for the system to perform a complete cardiac scan in less than five minutes acquisition time including myocardial perfusion imaging (MPI), Attenuation Correction, Computed Tomographic Angiography (CTA), and calcium scoring (CaSC). The speed and comprehensive nature of this procedure represents a significant improvement in patient care and diagnostic confidence. Providing with flexibility to manage dose more effectively, the Discovery NM/CT 570c, takes advantage of advances in both SPECT and CT technology. It reduces registration and motion artifacts by positioning the patient on the same table, and enables more convenient patient scheduling in comparison to separate, conventional SPECT and CT exams. Alcyone technology brings together a breakthrough design based on combining CZT detectors, focused pin-hole collimation, stationary data acquisition and 3D reconstruction, to improve workflow, dose management, and overall image quality. Unlike conventional nuclear imaging, all views are acquired simultaneously during a fully stationary SPECT acquisition, eliminating equipment movement during the scan and reducing the risk of motion artifacts. CZT detectors directly convert gamma rays into digital signals, eliminating the need for photomultiplier tubes, but maintaining high stopping power to deliver improved energy, spatial and temporal resolution.
