*5: VOD=15 V, RL (load resistance of emitter follower)=1 kΩ
*6: Dark signal doubles for every 5 to 7 °C.
*7: Operating frequency is 1 MHz.
*8: Dynamic range = Full well capacity / Readout noise
*9: X-ray irradiation of 60 kVp, measured at half of the full well capacity
*10: XRNU (%) = Noise / Signal × 100
Noise: Fixed pattern noise (peak to peak)
In the range that excludes 5 pixels from edges to the center at every position
*11: Refer to “Characteristics and use of FFT-CCD area image sensor” of technical information.
*12: White spots > 10 times of Max. Dark signal (2500 e^-/pixel/s)
Black spots > 50 % reduction in response relative to adjacent pixels, measured at half of the full well capacity
*13: Continuous 2 to 9 point defects
