The GE Advance NXi PET system is optimized for routine 2D and 3D clinical studies. The Advance NXi has capabilities for imaging all available PET tracers and provides superior image quality, high throughput, easy operator interaction and proven reliability. The uncompromising design of the Advance’s high-speed detection system results in high-resolution image quality without sacrificing count rate performance and sensitivity necessary for fast acquisitions. Furthermore, the Advance does not use data reduction techniques such as “mashing” which are known to degrade image resolution and result in quantitative uncertainties. The Advance NXi is the perfect choice for cardiac imaging as compared to other PET-only imaging systems:
