Optiso HD digital detector
Setting the standard in PET/CT with digital LSO-based detectors
Biograph™ mCT and Biograph Horizon digital detectors offer PET/CT imaging with high, 78-mm3 volumetric resolution2 due to the small, 4 x 4-mm lutetium oxyorthosilicate (LSO) crystal elements and the ability to offer True TOF for performance and clinical advantages.

4.0-mm LSO crystals
True TOF technology
For small segments of response
All Biograph PET/CT scanners are TOF-capable to enable lower doses and faster scan times. By measuring the difference between the detection of each coincidence photon, they can better determine the event location along the line of response. This allows for smaller segments of response—increasing the accuracy of locating the annihilation event. TOF effectively boosts the clinical performance of PET scans. Faster TOF better localizes each event and reduces noise within the reconstructed image.
