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.dition 5.0 2020-12
