General information
X-ray beam:
Reconstruction Algorithm:
Dynamic Range:
Scan Time (sec) at normal:
Rotating Unit Scan Angle (degree):
Actual rotating angle around the object
X-ray Exposure Angle (degree):
Actual spanning angle to expose the object to X-Ray: In fact the instant that the rotating
unit turns by 10 degrees, the X-Ray exposure starts and stops at 10 degrees before the
rotating unit reaches the full rotation: 240-10-10=220
