Medical electrical equipment - Medical image display systems - Part 2: Acceptance and constancy tests for medical image displays

This part of IEC 62563 establishes the performance CRITERIA and test frequencies for the ACCEPTANCE TESTS and CONSTANCY TESTS. The evaluation methods are defined in IEC 62563-1. The scope of this document is directed to practical tests that can be visually evaluated or measured using basic test equipment. This document applies to medical IMAGE DISPLAY SYSTEMS, which can display monochrome image information in the form of greyscale values on colour and greyscale IMAGE DISPLAY SYSTEMS.

FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC 62563-2 has been prepared by subcommittee 62B: Diagnostic imaging equipment, of IEC

technical committee 62: Electrical equipment in medical practice.
The text of this International Standard is based on the following documents:

INTRODUCTION

This document defines ACCEPTANCE and CONSTANCY TESTS for medical image displays. It defines

TEST ITEMS for the ACCEPTANCE and CONSTANCY TESTS, as well as the performance CRITERIA and

the test frequency for each TEST ITEM, elements of the measurement method related to an image

quality parameter in an IMAGE DISPLAY SYSTEM. The evaluation methods of the TEST ITEMS are

not described in this document; rather, evaluation methods, along with prerequisites, equipment

and tools for the TEST ITEMS, are defined in IEC 62563-1.

ACCEPTANCE and CONSTANCY TESTS are performed on site at the installation facility. An

ACCEPTANCE TEST is carried out after a new IMAGE DISPLAY SYSTEM has been installed or major

modifications have been made to the existing IMAGE DISPLAY SYSTEM. Since an IMAGE DISPLAY

SYSTEM can degrade over time, CONSTANCY TESTS are carried out periodically to verify that the

performance is maintained.

This document describes appropriate TEST ITEMS and CRITERIA that are considered appropriate

as an international standard based on survey of quality control testing standards and guidelines

across the world. Although other existing standards and guidelines have been defined by other

standard organizations and can be given priority over this document, national authorities are

encouraged to adopt or harmonize to this document.

4 General

In IMAGE DISPLAY SYSTEMS, every individual component can limit or reduce the image quality of

the system. Therefore, it is necessary to adopt suitable measures for quality monitoring. If IMAGE

DISPLAY SYSTEMS are correctly adjusted and maintained, these devices can consistently

generate similar images.

Simple test equipment is used (LUMINANCE meter, TEST IMAGES) with PRECISION appropriate for

a test. Before a test, all test equipment shall be checked for its functioning according to the

MAGE DISPLAY DEVICE should be placed in a likely clinical position
manufacturer’s specifications. I
while performing the measurements.

According to Clause 5, IMAGE DISPLAY DEVICES shall be categorized, and ACCEPTANCE TEST and

CONSTANCY TEST shall be performed respectively. ACCEPTANCE TEST shall be performed after a

new IMAGE DISPLAY SYSTEMS installation or major modification of an existing IMAGE DISPLAY

SYSTEM. The CONSTANCY TEST shall be performed periodically to confirm that the performance

is maintained.

The results of ACCEPTANCE and CONSTANCY TESTING shall be recorded. If the test did not meet

the CRITERIA, immediate response (e.g., as recommended by the IMAGE DISPLAY DEVICE

manufacturer) such as repair service, re-calibration, or replace of IMAGE DISPLAY DEVICE (s) shall

be performed. It is optimal to manage systems properly and not fail the tests. If tests fail,

analysis of results or more frequent testing is advisable. Testing conditions, test instruments,

TEST PATTERNS and evaluation methods are defined in IEC 62563-1. Annex A shows a sample

ACCEPTANCE and CONSTANCY TEST report.

5 Categories

IMAGE DISPLAY DEVICES shall be categorized in three categories: I, II and III. Category I is further

categorized in 2 subcategories: I-A and I-B.
The following application categories and subcategories are defined.

Category I-A: IMAGE DISPLAY DEVICE which has at least a 2 048 × 2 048 pixel array size and

a GSDF LUMINANCE response. This category is recommended if consistent

visibility of subtle contrast and finest detail is required for accurate diagnosis.

Application examples include mammography and digital breast
tomosynthesis.

Category I-B: IMAGE DISPLAY DEVICE which has at least a 1 024 × 1 024 pixel array size and

a GSDF LUMINANCE response. This category is recommended if consistent

visibility of low contrast and fine detail is required for the clinical application.

Application examples include images such as chest X-ray, CT and MR, and
breast biopsy.
