适用范围：This European Standard specifies a method for the measurement of focal spot dimensions above 0,2 mm ofX-ray systems up to and including 500 kV tube voltage by means of the pinhole camera radiographic method.The voltage applied for this measurement is restricted to 200 kV for visual film evaluation.The image quality and the resolution of X-ray images depend highly on the characteristics of the focal spot, inparticular the size and the two dimensional intensity distribution.For the characterisation of commercial X-ray tube types (i.e. for advertising or trade) the specific values ofTable A.1 are used.
