Principle

The quality of the image will improve with a number of
parameters. In this experiment the different fac-tors influencing
the quality of the CT Scan are investigated. One of the most
important parameters is the number of projections. This is due to a
longer scan time which results in better image quality and less
noise and to the fact that more sampling has been taken and the
features of the sample can be recon-structed more accurately. The
accuracy and quality of the reconstruction improves not only with
the number of projections but also with the total angle the
projections were taken under. Optimal results are achieved with
360°.
