Q.Clear
GE HealthCare's Bayesian penalized-likelihood PET reconstruction algorithm. Combines maximum-likelihood iterative reconstruction with a Bayesian prior (penalty term) that regularizes noise while preserving small-lesion conspicuity. Ships across the current GE PET/CT line — Discovery IQ, Discovery MI, and the current Omni Legend — and is cited as a clinical differentiator for small-lesion oncology PET.
Why it matters to buyers: Q.Clear is a GE PET reconstruction differentiator vs competitor-OEM reconstructions (Siemens TrueX, Philips BLOB). License status on pre-owned Discovery IQ / MI is a meaningful acceptance-test item.
Why it matters to engineers: Q.Clear is reconstruction-software licensed on the PET host. Reconstruction timing, GPU health, and Q.Clear-specific QC are commissioning items. Point-spread-function modeling integrated into the Q.Clear pipeline.
