Sažetak
Dimensions of an x-ray tube focal spot were measured using pinhole camera, star test pattern and multiple bar pattern. The width of the examined focal spot was found to lie within the tolerance limits, but its length was twice larger than the stated one. Comparison of the applied methods has given no evidence for the tentative factor of 0.7 proposed by ICRU for correction of the focal spot length when measured with a pinhole camera. Dependence of the focal spot size on tube current and tube voltage was examined.
