The latest version of Siemens' biograph is running at Hong Kong Baptist Hospital. The system features an advanced detector made from lutetium oxyorthosilicate (LSO), a scintillator whose high-speed properties allow shorter scan times and faster patient throughput. PET and CT data can be acquired in 20 minutes or less on the LSO product, according to the company. The biograph is also available with detectors using a BGO (bismuth germanate) crystal. The first commercial installation of the BGO system was completed last fall at Memorial Sloan-Kettering Cancer Center in Manhattan.
