Today, I will popularize the knowledge about the pixel size of the flat panel detector.
The first DR flat-panel detector appeared in 1995. The DR flat-panel detector is the core technology of DR technology and plays a decisive role in its imaging quality. From the perspective of energy conversion, it can be classified into direct conversion flat panel detectors and indirect conversion DR flat panel detectors. The material is different, the indirect DR flat panel detector is made of amorphous silicon. The direct type DR flat panel detector is made of amorphous selenium.
Flat panel detector category: amorphous silicon scintillator: gadolinium oxysulfide/cesium iodide Image size: 35cm×43cm pixel matrix: 2560×3072cm pixel pitch: 140μmA/D conversion: 16bit spatial resolution 3.6LP/mm Wired/wireless): 1s/2.5s X-ray working range: 40-150KV battery standby time: 8 hours wireless battery standby time: 10 hours data interface: GigE/802.11n, ac power: 20W adapter input AC: 100-240V, 50-60Hz adapter output DC: 24V, 60W Detector size: 38×46×1.5cm Detector weight (wireless with battery/wired): 3.3kg/2.9kg Detector housing material: carbon plate, magnesium alloy Waterproof rating: IPX3 Working environment: 5-35ºC, 10-75%RH
The pixel size of the flat panel detector is generally: 109um, 119um, 139um, 149um, 159um.
