31、nal Standards which give methods of acceptance testing and constancy testing for subsystems and systems (e.g. diagnostic X-RAY EQUIPMENT), including film processing, used in medical imaging departments. 1 Scope and object 1.1 Scope This part of IEC1223applies to those components of X-RAY EQUIPMENT w
32、hich influence the image quality of EQUIPMENT for digital subtraction angiography (DSA) with an imaging system consisting of an X-RAY generation subsystem, a detection device comprising an X-RAY IMAGE INTENSIFIER television chain, means of digitization and digital image processing, image storage and
33、 image manipulation including subtraction, and facilities for image display. This standard does not apply to general equipment of digital imaging. If such an equipment includes a DSA function, it is restricted to the DSA function. 1.2 Object This part of IEC1223defines: a) the essential parameters w
34、hich describe the performance of the above-mentioned components of X-RAY EQUIPMENT with regard to imaging properties; b) methods of testing whether measured quantities related to those parameters comply with specified tolerances. These methods mainly rely on non-invasive measurements using appropria
35、te test equipment performed during the installation or after the installation is completed. Signed statements covering steps in the installation procedure can be used as part of acceptance testing. The aim is to verify compliance of the installation with specifications affecting the image quality, a
36、nd to detect malfunctions affecting the image quality that are not in agreement with those specifications. This standard does not in itself specify tolerances for the parameters under investigation. Neither is it intended to consider: c) aspects of mechanical and electrical safety; d) aspects of mec
37、hanical, electrical and software performance unless they are essential to the performance of the tests directly affecting the image quality. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC122
38、3. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC1223are encouraged to investigate the possibility of applying the most recent editions of the normative documents listed below.

44、3.2 Use of terms In this part of IEC1223, terms printed in SMALL CAPITALS are used as defined in IEC788or other IEC publications or in3.3 of this standard; seeAnnex A. Where a defined term is used as a qualifier with another defined or undefined term it is not printed in SMALL CAPITALS, unless the c
45、oncept thus qualified is defined, or recognized as a derived term without a definition. NOTEAttention is drawn to the fact that, in cases where the concept addressed is not strongly confined to the definition given in one of the publications listed above, a corresponding term is printed in lower-cas
46、e letters. 3.3 Defined terms 3.3.1 ARTIFACT apparent structure visible in the image which does not represent a structure within the object and which cannot be explained by noise or the MODULATION TRANSFER FUNCTION of the system 3.3.2 DSA CONTRAST SENSITIVITY ability of the DSA system to display low

48、on 4 General aspects of ACCEPTANCE TESTS 4.1 General conditions to be considered in test procedures The aim of an ACCEPTANCE TEST is to demonstrate that the specified characteristics of the EQUIPMENT lie within the specified tolerances. Some requirements are enforced by legislation. Other requiremen
49、ts and specifications may be in the order contract, in the suppliers brochure or in other standards, e.g. IEC601series. Prior to the performance test procedures an inventory of the EQUIPMENT under test shall be established. The X-RAY EQUIPMENT and its components shall be unambiguously identified, e.g.with respect to type and SERIAL NUMBER, and checked against the order contract. The check shall also encompass ascertaining that the ACCOMPANYING DOCUMENTS, including test protocols, are complete, that delivery
