This document specifies the measurement procedures for determining some of the main image quality parameters of magnetic resonance equipment. This document is applicable to:
——Quality evaluation during acceptance tests;
——Quality assurance during stability tests.
Note 1: Not all tests provide the performance levels required for acceptance tests.
This document is not applicable to:
——Determining performance levels during acceptance tests and stability tests;
——Image quality evaluation of high-field magnetic resonance equipment greater than 8 T, unless otherwise specified;
——Image quality affected by magnetic resonance compatibility issues;
——Special diagnostic procedures, such as blood flow imaging, perfusion, diffusion, radiotherapy, and image-guided therapy applications;
——Type testing.
Note 2: The scope of this document is also limited to measuring image quality characteristics collected on test phantoms, rather than on patient images.
Note 3: All methods in this document have not been extensively tested at a static magnetic field strength of more than 3 T. Initial tests indicate that these methods can function properly when using appropriate test phantom fillers.
