34、for subsystems and systems (for example diagnostic X-RAY EQUIPMENT), including film processing, used in medical imaging departments. Some provisions or statements in this standard require additional information. Such information is presented in annex D. An asterisk in the left margin of a clause or

36、radioscopic systems 1 Scope and object 1.1 Scope This part of IEC 61223 applies to those components of X-RAY EQUIPMENT which influence the image quality and PATIENT dose of diagnostic X-ray systems using radiographic and radioscopic imaging systems. This standard applies to the performance of X-RAY
37、EQUIPMENT in the ACCEPTANCE TEST On the f0llOWing medical diagnostic X-RAY EQUIPMENT and ASSOCIATED EQUIPMENT: - radiography equipment, for example: Stationary radiography EQUIPMENT; mobile radiography EQUIPMENT; S kull radiography EQUIPMENT; lung radiography EQUIPMENT; TOMOGRAPHY EQUIPMENT - exclud
38、ing COMPUTED TOMOGRAPHY; radiography devices (SPOTFILM DEVICES) in RADIOSCOPY EQUIPMENT; angiography EQUIPMENT (excluding DSA function); CINERADIOGRAPHY equipment; - RADIOSCOPY EQUIPMENT, including: combined radiographic and radioscopic EQUIPMENT. This standard applies to the generation of X-RADIATI
39、ON and ACCESSORIES of digital systems. it does not apply to any digital image acquisition or image processing parts of the above mentioned diagnostic X-RAY EQUIPMENT. NOTE - Since the characterization of digital detectors and image processing is still under development, this will be included in a la
40、ter edition of this standard. This standard does not apply to mammographic X-RAY EQUIPMENT, RADIOTHERAPY SfnUlatOrS, nor to dental X-RAY EQUIPMENT. 1.2 Object This standard defines: a) the parameters which describe the performance of X-RAY EQUIPMENT with regard to imaging properties and PATIENT dose
41、; b) methods of testing whether measured quantities related to those parameters comply with the specified tolerances. STDIBSI BS EN bL223-3-3-ENGL L999 lb24bb9 0789290 - “should“ - “may“ - “specific“ indicates a strong recommendation that is not mandatory for compliance; indicates a permitted manner
42、 of complying with a requirement or of avoiding the need to comply; is used to indicate definitive information stated in this standard or referenced in other standards, usually concerning particular operating conditions, test arrangements or values connected with compliance; - “specified“ is used to
43、 indicate definitive information stated by the MANUFACTURER in under consideration, usually concerning its intended purposes, or the parameters or conditions associated with its use or with testing to determine compliance.

49、acteristics of the equipment lie within the specified tolerances. Some requirements are enforced by legislation. Other requirements and specifications may be in the order contract, in the suppliers brochure or in other standards, for example in the IEC 60601 series. General conditions to be considered in test procedures Before any ACCEPTANCE TEST according to this standard is carried out, the EQUIPMENT has to be installed and put into service according to the set-up procedure as given in the MANUFACTURERS documentation.
