General Information
The general information lists the specifics of the calibration including the part, system, and date.
Cylinder Diameter
The cylinder diameter lists the actual diameter, the measured cylinder diameter, and the
difference between the two.
Spatial Calibration
The spatial calibration analyzes the geometrical sharpness of the image. Geometrical blurriness
limits the ability to image an object's fine structural detail.
Noise Level
Noise is expected and acceptable. Excessive noise limits the ability to detect the presence or
absence of features in an object.
Point Spread Function (Full Width at Half Maximum)
The point spread function gives the measurement of the sharpness of an image.
Modulation Transfer Function (50% level)
The modulation transfer function illustrates the system's spatial frequency response in the
reconstruction volume.
