In the diagnostic and preoperative procedures using the CT required is imaging and reconstruction of the spatial structures of the tissue with the analysis of dimensionally-shaped. The aim is to analyze the selected procedures for assessing the accuracy of mapping of geometrical parameters in CT using the pattern to the compare diagnostic equipment at an angle measurement applications. Tomographic studies of patterns balls and pattern of the Ball Bar type was performed using 64-layer of CT scanner Somaton Siemens Cardiac. The accuracy of the mapping was done by comparing the reconstructed of patterns models based on CT imaging of geometrical parameters contained in the certificates. Implementation of the comparison performed by Best Fit using programs: 3D Reshaper, Poly Works, Geomagic, Amira. Results The results of the assessment of the mapping of selected geometric parameters tested patterns are shown in the form of maps of accuracy mapping the surface of the patterns balls, determination of the diameters value and experimental standard deviations for the balls made of different materials. In addition, the measurement uncertainty distance between centers of the balls and measurement uncertainty of balls diameter were determined for the patterns of the Ball Bar Conclusions CT introduces an error of accuracy the geometry mapping resulting from the size, shape and material, position of the scanned surface of a spherical relative to the gantry and the location of the object in space research.
