Determination of the maximum symmetrical radiation field from a rotating anode X-ray tube for medical diagnosis

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.
