Figure 2: Result screen of the program after successful execution. The axes of the figures are in pixels. The top two figures display the slices with the first and second markers, while the bottom figures illustrate the smaller area within which the program searches for the markers.

The tolerance values are as follows: 1mm for lateral deviation, 2mm for vertical deviation and 0.3º for transversal torsion.

Conclusion:

The work conducted will enable the automatic and unbiased analysis of couch sag in a tomotherapy system.
