scope:

This international standard specifies measurement procedures for the determination of many essential medical MR EQUIPMENT image quality parameters. Quality assessment as addressed in this standard consists of;
- 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, but is not an objective of this standard.
This standard does not directly address:
- required levels of performance for ACCEPTANCE TEST and CONSTANCY TEST;
- image quality assessment of high field MR EQUIPMENT greater than 4 Tesla, 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.
These procedures are directed to:
1) MANUFACTURERS, who can demonstrate compliance by performing acceptance and constancy methods as described by this standard,
2) test houses, who can confirm performance of MR EQUIPMENT using methods described in
this standard,
3) regulatory authorities, who can reference this standard, and
4) USERS who can perform acceptance and constancy tests based on methods described in
this standard.
