Newheek amorphous silicon flat panel detector

The Newheek flat panel detector is a high performance, cassette-sized wireless flat panel detector. It can last for at least 10 hours, and the unique wireless transmission technology can complete a full-resolution image transmission in 3 seconds, even in the worst case, no more than 5 seconds. At the same time, the detector has excellent quality such as high DQE and high resolution. The detector is highly sensitive and supports automatic exposure detection, making it easy to connect and synchronize with all high vChest rack type for flat x-ray detectoroltage generators.

Amorphous silicon flat panel detector
It is mainly composed of a scintillator, a photodiode circuit made of amorphous silicon, and an underlying TFT charge signal readout circuit. During operation, the Xray photon-excited scintillator has produced fluorescence, and the spectral range of the fluorescence is around 550 nm, which is the sensitivity peak of amorphous silicon. Fluorescence is transmitted through the needle crystal to the amorphous silicon diode array, which receives the fluorescent signal and converts it into an electrical signal, which is sent to the corresponding amorphous silicon thin film transistor and forms a stored charge on its capacitance, by the signal readout circuit And send the computer to reconstruct the image.
