DESCRIPTION

BS EN 61223-2-5:1995


This standard BS EN 61223-2-5:1995 Evaluation and routine testing in medical imaging departments. Constancy tests is classified in these ICS categories:
  • 11.040.50 Radiographic equipment

1.1 Scope

This part of IEC 1223 applies to image display devices as used in diagnostic imaging systems such as:

  • digital radiography;

  • digital subtraction angiography;

  • computed tomography;

  • magnetic resonance imaging;

  • ultrasonic diagnostic equipment;

  • nuclear medicine.

*The test methods are based on the use of test patterns.

*This standard does not apply to video monitors used in indirect radioscopy systems.

This standard is a part of a series of Particular Publications (standards and technical reports) which give methods of tests for the constancy of properties of diagnostic imaging systems as described in IEC 1223-1 (see clause 2).

1.2 Object*

This part of IEC 1223 defines:

  1. the functional parameters which describe or affect the performance of the above components of diagnostic imaging systems; and

    the functional parameters which describe or affect the performance of the above components of diagnostic imaging systems; and

  2. methods of checking that variations in measured quantities related to those parameters are within acceptable limits, in order to maintain adequate standards of imaging whilst, in the case of x-ray equipment, avoiding unnecessary irradiation of the patient.

The methods are based upon assessments of representations of appropriate test pattern.

The aims are:

  • to establish a reference level of performance when equipment is accepted;

  • to detect and verify any significant variation in performance which may require corrective action.

In some cases, reference is made to procedures, described in other related publications, which for practical reasons are carried out prior to the application of the procedures described in this standard (see clause 2).

Because radiological installations differ widely from each other, this standard does not specify values and tolerances for the parameters which are generally applicable as criteria of acceptable performance. However, guidance is given to indicate the degree of variation in single measurements which might require appropriate action.

This standard does not deal with:

  1. aspects of mechanical and electrical safety;

  2. optimization of imaging performance.

*This part of IEC 1223 describes a method to check, in terms of functional parameters, the constancy of the quality of images reproduced by image display devices in order to ensure that the required conditions for displaying images of consistent quality are maintained, after the calibration and adjustment have been carried out.
