3.1.2 Detector Operation Conditions
 X-ray energy range
The detector operates at the following X-ray tube peak voltages:
 X-ray tube peak voltages: Min = 40 kVp
 X-ray tube peak voltages: Typ = 70 kVp
 X-ray tube peak voltages: Max = 150 kVp
 X-ray exposure range
The detector operates within the linearity specifications up to an X-ray exposure value of 100μGy.
The detector operates within the degraded linearity specifications above 100μGy and up to an
X-ray exposure value of 130μGy.
 X-ray source position
The angle between the X-ray central propagation axis and the normal axis of the front-end
entrance plane taken at the centre point of the matrix should remain within the following range:
 X-ray angle: Min = -45 deg
 X-ray angle: Typ = 0 deg
 X-ray angle: Max = +45 deg
The distance between the X-ray source focal spot and the front-end entrance plane (SID) should
remain within the following range:
 SID: Min = 100 cm
 SID: Typ = 135 cm
 SID: Max = 180 cm
 X-ray window duration
While the X-ray window duration can be functionally settled by the system over a wide range,
image quality can be directly impacted by X-ray window duration (due to leakage, noise, or lag).
The full performance of the detector is guaranteed for the following X-ray window range:
 X-ray window duration: Min = 10 ms (TBC)
 X-ray window duration: Typ = 500 ms (TBC)
 X-ray window duration: Max = 2500 ms (TBC)
