The Siemens brand is not in doubt.
Working principle:
The core component of the flat panel detector (referred to as FD), the size of 30cm × 40cm, the use of amorphous silicon and CSI scintillator, the maximum acquisition speed of 30 frames / sec.
Working disadvantages:
In order to ensure that the FD image quality is stable, its temperature control unit must be constant, with a deviation of no more than ± 0.5 ℃ / 2 minutes. If out of range or abnormal working condition will cut off the X-ray and stop the whole machine. Bringing danger to the patient's life. Therefore, technicians must regularly check whether the coolant height is within the standard range.
