active, Most Current
Organization: CENELEC
Publication Date: 1 February 2021
Status: active
Page Count: 50
ICS Code (Radiographic equipment): 11.040.50
scope:

This document applies to FOCAL SPOTS in medical diagnostic X-RAY TUBE ASSEMBLIES for medical use, operating at X-RAY TUBE VOLTAGES up to and including 150 kV.

This document describes the test methods employing digital detectors for determining:

a) FOCAL SPOT dimensions in terms of NOMINAL FOCAL SPOT VALUES, ranging from 0,1 to 3,0;

b) LINE SPREAD FUNCTIONS;

c) one-dimensional MODULATION TRANSFER FUNCTIONS;

d) FOCAL SPOT PINHOLE RADIOGRAMS,

and the means for indicating compliance.

In informative annexes, STAR PATTERN imaging and BLOOMING VALUE are described.
