GE FlashPad / FlashPad HD Wireless DR Detector
GE HealthCare's wireless flat-panel DR detector family. Amorphous-silicon TFT array with CsI(Tl) scintillator in a single-panel, non-tiled construction. 100 µm pixel pitch, 5.0 lp/mm limiting resolution, ~75% DQE at 0 lp/mm. FlashPad ships across the Discovery XR656 fixed DR room, Optima XR656, and Optima XR220amx portable DR systems — the same detector can be moved between rooms within GE's DR ecosystem, a meaningful fleet-management advantage. FlashPad HD is the higher-resolution variant on Discovery XR656 HD configurations.
Fits
Specs
- Amorphous-silicon TFT + CsI(Tl) scintillator (indirect conversion)
- Single-panel, non-tiled construction
- 100 µm pixel pitch
- 5.0 lp/mm limiting resolution
- ~75% DQE at 0 lp/mm
- 14 × 17″ wireless cassette form factor
- Ultra-Wideband wireless communication
Diagnosis
- Battery aging — typically 3–4 years of useful life; mid-shift swap demands signal battery replacement.
- Scintillator degradation — CsI efficiency drops gradually; measured against baseline DQE.
- Drop damage — wireless panels get dropped. Inspect housing, active area, connector; run panel-calibration phantom after any drop.
- Wireless communication dropout — Ultra-Wideband interference or pairing issue; verify detector registration in OEM service utility.
- Bad-pixel growth — monthly bad-pixel map review catches it.
Replacement
Battery is a routine service item — scheduled replacement at typical 3–4 year interval. Full detector replacement is a larger event. Detector pairing / registration in the OEM service utility is mandatory when introducing a new or relocated FlashPad to a room.
