DISCUSSION

In order to evaluate the goodness of our method to obtain the 3-D position of the reference points placed on the patient´s back, a previous study was realised to verify the measures quality within the volume of space where the patient would be placed.

This was achieved placing a reference bar with two points separated 500 mm. Three images were taken with three different bar orientations (horizontal, vertical and oblique) within the volume of interest. The real world coordinates were calculated for this points and the results are summarized in the table tab. 1.

The obtained distances for the different positions of the bar are

Horizontal Point: d=499.2437 mm

Vertical Point: d=497.0056 mm

Oblique Point: d=495.1592 mm

The obtained results are very close to real distances. Thus, the experimental estimated error is less than 1%.
