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
