Description
IEC 60336:2020 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.
IEC 60336:2020 cancels and replaces the fourth edition published in 2005. This edition constitutes a technical revision.
The significant changes of this fifth edition with respect to the previous edition are detailed in Clause E.6. These changes are:
a) introduction of digital detectors and discretization errors;
b) fewer normative requirements;
c) support for both SLIT CAMERA and PINHOLE CAMERA;
d) reintroduction of distorted (skewed) FOCAL SPOT;
e) keeping of STAR PATTERNS and BLOOMING VALUE as informative.
