LSO scintillator

For faster time of flight and better image quality

We are the only PET manufacturer that owns the entire manufacturing process for the detector. It allows us to closely control the process quality and gives us the flexibility to explore different detector designs to reach an optimal solution for a complete detector redesign.

  • Grown, cut, and individually selected in-house
  • Self-manufactured to enable precise specifications and complete detector redesign
  • Higher light output and faster scintillation,1 enabling faster time of flight and better image quality

For optimized performance

Time of flight performance depends on collecting light from all photons in the scintillation. The Optiso UDR detector is designed so SiPMs cover the entire LSO-array area, allowing all light from the scintillation to be detected. This leads to 100% coverage3 and enables fast temporal resolution.
  • Provides 214 ps (picosecond) temporal resolution3 for the best-in-class time of flight and effective sensitivity
  • 3.9x time of flight gain amplifies4 scanner sensitivity for faster scans and lower dose

Faster time of flight reduces noise

Increased detectability of small lesions.

Time of flight performance at 228 ps enables small segments of response.

What is UDR?

The Optiso Ultra Dynamic Range (UDR) detector uses multiple technologies to provide optimal performance in a wide range of count rates. Fast time of flight and high effective sensitivity provide excellent performance in low and medium activity ranges such a 90Y, 18F, and 68Ga applications.

A small block detector with low dead time makes it suitable to operate in the high-activity concentrations found in studies with very short-lived tracers, such as 82Rb and 15O.

Biograph Vision and its features and applications are not commercially available in all countries. Their future availability cannot be guaranteed. Please contact your local Siemens Healthineers organization for further details.
