Unlike analog PET/CT scanners that use photomultipliers, or analog SiPMs to detect light, the Vereos PET/CT scanner uses proprietary Digital Photon Counting (DPC) technology. DPC technology converts light directly to a digital signal with zero analog noise.
Each crystal is connected to a single digital photon counting detector. This 1:1 coupling, combined with 325 ps Time-of-Flight (TOF) timing resolution and reduced pile-up effects, allows for a much higher count rate capability and improved spatial resolution compared to analog² systems.
≈ 2x volumetric resolution*
The system uses 1:1 coupling of crystals to digital detectors. This means spatial, timing, and energy resolution is improved throughout the entire field of view, for improved volumetric resolution.
≈ 2x sensitivity gain*
Philips Digital Photon Counting technology converts light directly to a digital signal. Because there is virtually no noise introduced in this conversion, the system improves the signal-to-noise ratio which enables improved sensitivity.
≈ 2x quantitative accuracy*
Vereos has improved quantitative accuracy of +/- 5% when compared to +/- 10% seen with analog systems.²
Premium image quality
iDose⁴ improves image quality⁴ through artifact prevention and increased spatial resolution at low dose.
Improved workflow efficiency
iPatient drives confidence and consistency through personalized patient-centric workflow. The iPatient platform can reduce time-to-results by 24% and clicks per exam by 66%⁵.
(1) Improved image quality is defined by improvements in spatial resolution and/or noise reduction as measured in phantom studies.
