Siemens Biograph 16

The Siemens Biograph 16 is a whole-body CT scanner ideal for oncological imaging
and diagnosis. The Siemens Biograph 16 produces excellent images,
inherently registered, that show detailed anatomy and biological processes at
the molecular level, with just one noninvasive procedure.
The Siemens Biograph 16 features LSO detector design, exceptional imaging quality,
16-slice CT detectors, a spacious gantry for flexible patient positioning,
higher definition imaging with PET HI-REZ, the syngo multimodality computer system,
as well as a small footprint for easy siting.
