*2: Internal trigger mode, single operation
*3: At 80 kVp without filter
*4: Spatial frequency at CTF=5 %
*5: A defect line is a horizontal or vertical line containing 4 or more pixels that produce less than 1/8 of the average output from
surrounding pixels and are formed continuously from the opposite side of an amplifier array or a vertical shift register.
Without a couple of adjacent defect line.
*6: Average of all effective pixels in single operation at Sf (int)
Note: X-ray energy range is 20 k to 100 kVp.
