Beam
z
Reconstruction Algorithm:
A real time reconstructing algorithm
z
Dynamic Range:
14 bit
z
Scan Time (sec) at normal:
9.7 sec (typical). (2~13.5 sec.)
z
Rotating Unit Scan Angle (degree):
240
Actual rotating angle around the object
z
X-ray Exposure Angle (degree):
220
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
