Full title and description

St IEC 62464-1-2018 — Magnetic resonance equipment for medical imaging — Part 1: Determination of essential image quality parameters. This international standard specifies measurement procedures and reporting methods for a set of essential MRI image‑quality parameters used in acceptance and constancy testing of MR equipment.

Abstract

IEC 62464-1:2018 defines preferred measurement procedures and alternative normative methods for evaluating essential image quality characteristics (for example signal‑to‑noise ratio, uniformity, slice thickness for 2‑D scans, two‑dimensional geometric distortion, spatial resolution and ghosting artefacts) on test devices intended for MR equipment acceptance and routine constancy testing. The standard focuses on procedures performed on test phantoms (not on patient images) and provides reporting guidance to support quality assurance programs.

Scope

Provides standardized procedures for the determination of essential image quality parameters of magnetic resonance (MR) equipment for medical imaging. Procedures are intended for acceptance testing and constancy (quality assurance) testing and are specified for use with TEST DEVICES (phantoms) — not for evaluation of patient images. The document lists the measured parameters (SNR, uniformity, 2‑D slice thickness, 2‑D geometric distortion, spatial resolution, ghosting artefacts), describes system and phantom requirements, scan parameters, data analysis, tolerances and reporting, and notes limitations (for example it does not address MR equipment with static magnetic field intensity greater than 8 tesla, MR‑compatibility issues, certain specialised diagnostic procedures, or type tests).

Key topics and requirements

• Defined measurement procedures for essential image quality parameters: signal‑to‑noise ratio (SNR), uniformity, slice thickness (2‑D), 2‑D geometric distortion, spatial resolution, and ghosting artefacts.
• General system and TEST DEVICE (phantom) requirements, recommended scan parameters, and reporting formats to ensure repeatability and comparability.
• Guidance for acceptance testing and constancy (routine QA) testing; preferred methods with alternative normative methods provided in Annex A.
• Emphasis on consistently repeatable, preferably automated measurement methods to support trend analysis and frequent quick testing.
• Notes on limitations and exclusions (e.g., field strengths above 8 T, specialised diagnostic sequences, patient‑image assessment).

Typical use and users

Used by MR equipment manufacturers to demonstrate performance at delivery (acceptance), by hospital/clinic medical physics and imaging QA teams for constancy testing, by independent test houses and calibration laboratories to verify MR system performance, and by regulatory authorities or responsible organisations as a referenced method for imaging quality assurance programs.

Related standards

IEC 62464-1:2018 cancels and replaces IEC 62464-1:2007 (first edition). The document has been adopted in regional/national collections (for example EN IEC 62464-1:2019). It was developed by IEC technical committee TC 62/SC 62B (medical imaging equipment, software and systems) and is related in application to other medical‑imaging and medical electrical equipment standards used for safety and performance testing.

A: IEC 62464‑1:2018 is an international standard that specifies measurement procedures to determine essential image quality parameters of magnetic resonance (MR) equipment for medical imaging.

Q: What does it cover?

A: It covers procedures, phantom and system requirements, scan parameters, analysis and reporting for parameters such as SNR, uniformity, 2‑D slice thickness, 2‑D geometric distortion, spatial resolution and ghosting; intended for acceptance and constancy (QA) testing on test devices rather than patient images. It also describes alternative normative methods and provides guidance for routine QA programs.

Q: Who typically uses it?
