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

The ankle and knee joints are clearly delineated, and the bones of the mid foot can be visualized as well. Papillary musculature and excellent definition of the aortic wall and cardiac chambers can also be seen.
With Biograph Vision precise localization of PET activity can be achieved, which can possibly affect patient management.

SiPM technology

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.

Optiso UDR detector

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.
