Mágneses rezonanciás berendezések gyógyászati képalkotáshoz. 1. rész: Alapvető képminőségi paraméterek meghatározása (IEC 62464-1:2007)

Magnetic resonance equipment for medical imaging. Part 1: Determination of essential image quality parameters (IEC 62464-1:2007)


This international standard specifies measurement procedures for the determination of many essential medical MR EQUIPMENT image quality parameters. Measurement procedures as addressed in this standard are suitable for: - quality assessment in the ACCEPTANCE TEST; - quality assurance in the CONSTANCY TEST. In addition, the measurement procedures specified in this standard may also be useful for type tests, although that is not an objective of this standard. This standard does not address: - required levels of performance for ACCEPTANCE TEST and CONSTANCY TEST; - image quality assessment of high field MR EQUIPMENT greater than 4 T, if not otherwise stated; - image quality affected by MR-compatibility issues; - special diagnostic procedures such as flow imaging, perfusion, diffusion, radiotherapy and image-guided therapy applications; - type tests. The scope of this standard is also limited to measuring image quality characteristics in TEST DEVICES, not in PATIENT images. The measurement procedures specified in this standard are directed to: a) MANUFACTURERS, who can demonstrate compliance by performing acceptance and constancy methods as described by this standard, b) test houses, which can confirm performance of MR EQUIPMENT using methods described in this standard, c) regulatory authorities, who can reference this standard, and d) RESPONSIBLE ORGANISATIONS who want to perform ACCEPTANCE and CONSTANCY TESTS using methods described in this standard. The essential image quality parameters and measurement methodologies defined in this standard are: - SIGNAL-TO-NOISE RATIO, - UNIFORMITY, - SLICE THICKNESS and SLICE PROFILE, - GEOMETRIC DISTORTION, - SPATIAL RESOLUTION, and - ghosting.
