Applies to X-RAY SOURCE ASSEMBLIES and X-RAY TUBE ASSEMBLIES containing ROTATING ANODE X-RAY TUBES, for use in MEDICAL DIAGNOSTIC RADIOLOGY for techniques in which the X-RAY PATTERN will be received simultaneously in all points of the IMAGE RECEPTION AREA.

1.1 Scope This standard is applicable to x-ray source assemblies and x-ray tube assemblies containing rotating anode x-ray tubes, for use in medical diagnostic radiology for techniques in which the x-ray pattern will be received simultaneously in all points of the image reception area. Unless otherwise specified, this standard is applicable to an x-ray tube assembly with a brand-new rotating anode x-ray tube. This standard does not apply to x-ray source assemblies and x-ray tube assemblies for special applications, when for example steeper variations of the air kerma rate or particular distributions are intended. 1.2 Object This standard describes a method for the determination of the greatest geometrically symmetrical radiation field at a specified distance from the focal spot for which the percentage air kerma rate along the major axes does not fall below a permitted value.
