1. Scintillator Selection: Needle CsI vs Turbid GadOx
Cesium Iodide (CsI) produces approximately double the optical signal efficiency of GadOx at zero spatial frequency. While GadOx detectors are $3,000–$6,000 cheaper, CsI enables 30% to 50% lower radiation exposure to patients for equivalent image contrast.
3. Point Load Capacity and Accidental Drop Coverage
Flat panel detectors are fragile optoelectronic instruments frequently dropped by patients or staff. Always look for IP67 water sealing and a manufacturer warranty that covers accidental drops from at least 1.0 to 1.2 meters onto solid steel.
