Next-generation PET/CT arrives

Siemens Medical Solutions will showcase a new biograph family of PET/CT scanners at the RSNA meeting. Features include a high-resolution PET option, image quality enhancement, a six-slice CT biograph companion to existing two- and 16-slice configurations, and high-performance image processing on an enhanced version of the Siemens' Leonardo workstation. Most notable is the introduction of an advanced form of lutetium oxyorthosilicate, the detector material. This form of LSO, called HI-REZ, promises a 250% improvement in volumetric image resolution, according to the company. The improved workstation integrates more than 50 multimodality imaging applications, including CT applications addressing radiation therapy planning and lung analysis, in a single user interface.
