_____________
Introduction to Amendment 1
This amendment is published to introduce colour measurement.

Since publication of IEC 62563-1:2009, IEC 61223-2-5, Evaluation and routine testing in

medical imaging departments Part 2-5: Constancy tests – Image display devices has been

reviewed and withdrawn.

1 Scope
Replace the first sentence of the third paragraph with the following:

This standard applies to medical IMAGE DISPLAY SYSTEMS, which can display image information

on greyscale and colour IMAGE DISPLAY SYSTEMS.
Add, at the end of the third paragraph, the following new sentence:

Handheld IMAGE DISPLAY SYSTEMS might require additional or modified versions of the

procedures described in this standard.
Replace, in the fourth paragraph, the word “nor” with “or”.
3.2 Symbols
Table 1 – Overview to the definitions of physical parameters
Add, before the last row, the following new row:
a L /L Alternative safety factor. This factor
R amb min
is defined to provide consistency
with other relevant documents
(e.g. ACR–AAPM–SIIM Technical
Standard For Electronic Practice Of
Medical Imaging, Amended 2014,
Resolution 39).
Replace, in the last row, third column, “Maximum distance” by “Distance”.
7.2 Evaluation method table overview

Table 3 – List of the evaluation methods that can be used for testing medical IMAGE

DISPLAY SYSTEMS

Replace, in the fourth but last row, first column, “Chromaticity evaluation” by “Chromaticity

uniformity evaluation”.

Replace, in the third but last row, “Chromaticity evaluation of multiple displays” by

“Chromaticity evaluation across multiple displays”.
Add, at the end of Table 3, the following new row:
Greyscale chromaticity evaluation Colour meter
7.4.4 LUMINANCE evaluation of multiple displays
Replace, in the last sentence, “average” by “lowest”.
7.4.5 Chromaticity evaluation
Replace the title of subclause 7.4.5 by the following:
7.4.5 Chromaticity uniformity evaluation

Add, before the existing first sentence of the second paragraph, the following new sentence:

---------------------- Page: 5 ----------------------
– 4 – IEC 62563-1:2009/AMD1:2016
© IEC 2016

The distance is calculated as the maximum for any two locations within the display screen.

7.4.6 Chromaticity evaluation of multiple displays
Replace the title of subclause 7.4.6 by the following:
7.4.6 Chromaticity evaluation across multiple displays

Add, in the second sentence of the first paragraph, after the word “measurements” the phrase

“for all IMAGE DISPLAY DEVICES”.
Delete, in the second paragraph, the words “deviation in”.
Add the following new subclause:
7.4.9 Greyscale chromaticity evaluation

With a colour meter, luminance and colour coordinates (u’, v’) are measured using TG18-LN

test patterns (TG18-LNx-i, i = 01, 02, …, 18). Measurements shall be performed without

ambient light. With only the measurements corresponding to recorded luminance values

higher than or equal to 5 cd/m , the distances in the u’,v’ plane with respect to the

measurement at full white (i.e. from TG18-LNx-18) are computed as
2 2 1/2
Δu' v' = ((u ’-u ’) + (v ’-v ’) )
i i i 18 i 18

The number of discarded measurements (luminance values less than 5 cd/m ) will vary

depending on the calibrated display function. For this reason, reporting greyscale chromaticity

results should be accompanied by the calibrated display function used for the display device

being measured.

The greyscale chromaticity is quantified as the maximum deviation in the computed

values.The greyscale chromaticity evaluation method described in 7.4.9 is applicable to both

colour and monochrome display devices.
