Method for supplying quality measure for X-ray picture recording system to produce three dimensional reconstruction, involves placing caliber object in X-ray picture recording system, where multiple calibration operations are carried out

摘要

The method involves placing (S10) a caliber object in an X-ray picture recording system. Multiple calibration operations are carried out (S12), where an effect of position is passed through and with each calibration operation. The X-ray of the calibration object is accommodated in each position. The projection parameters are utilized from each calibration operation for calculating (S20) a size and this size is utilized as quality measure.
