BS EN 61267:2006

What is BS EN 61267 - Radiation conditions for medical diagnostic X-ray equipment about?

BS EN 61267 is a European standard that provides radiation conditions for medical diagnostic X-ray equipment to improve the standards of operation of x-ray equipment.

BS EN 61267 applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic x-ray equipment, require well-defined radiation conditions.

BS EN 61267 deals with methods for generating radiation beams with radiation conditions that can be used under test conditions typically found in test laboratories or manufacturing facilities for the determination of characteristics of medical diagnostic x-ray equipment.

Note 1: Except for mammography, BS EN 61267 does not apply to conditions where discontinuities in radiation absorption of elements are deliberately used to modify properties of the radiation beam (for example by rare earth filters).

Note 2: Radiation conditions as used for screen-film sensitometry are not covered in BS EN 61267.

Who is BS EN 61267 - Radiation conditions for medical diagnostic X-ray equipment for?

BS EN 61267 on the radiation conditions for medical diagnostic X-ray equipment is useful for:

• Manufacturers of medical diagnostic X-ray equipment
• Test centres
• Testing institutes
• Service organisations and standardisation organisations
• Regulatory authorities

Why should you use BS EN 61267 - Radiation conditions for medical diagnostic X-ray equipment?

Radiation qualities are radiation beams emerging through filtration from the x-ray source assembly. radiation conditions represent the more general case, where scattered radiation emerges from an exit surface of a patient or a phantom. This requires a well-defined geometrical arrangement.

BS EN 61267 guideline assists you with radiation qualities in radiation beams emerging from the x-ray source assembly, radiation qualities based on a phantom made up of an aluminium added filter, radiation qualities based on copper added filter, and radiation qualities based on the copper added filter for determining characteristics for medical diagnostic x-ray equipment.

BS EN 61267 also guides the standard radiation conditions on RQN, RQB, RQR-M, RQA-M, RQN-M, and RQB-M.

With obedience and compliance to BS EN 61267, you can improve the standards of operation of x-ray equipment. In addition, assists you with uniform sets of radiation conditions for x-ray equipment for the determination of characteristics.

What’s changed since the last update?

BS EN 61267:2006 supersedes EN 61267:1994, which is withdrawn. BS EN 61267:2006 has made some technical changes compared to EN 61267:1994. These include:

• Introduction of “practical peak voltage” for measuring X-ray tube voltage
• Introduction of a new procedure for establishing the radiation qualities
• Inserting an informative Annex B “Determination of the amount of additional filtration” and a normative Annex C “Measurement of the practical peak voltage”
• Revision of radiation qualities and radiation conditions
• Addition of term definitions
