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 (TOF) and better image quality

Cardiology
01The 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.
High image quality with sharp definition of left ventricular margins with low noise on a 700 MBq (18.9 mCi) 82Rb for both stress and rest.
Excellent delineation of functioning cortex and sharp contrast between cortex and white matter. Additionally there is sharp basal ganglial edge definition, especially the sharp margins and distinct separation of the head of caudate nucleus and putamen.

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% coverage4 and enables fast temporal resolution.

Biograph Vision Quadra™ | 228 ps | 5.9 |
Ultra-fast time of flight benefits
- Improves signal-to-noise ratio enabling faster scans, lower injected dose, and better image quality2,4,5
- Increases detectability of small lesions
- Enables small segments along the line of response increasing the accuracy of locating the annihilation event
Optiso UDR detector
What is UDR?
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.
