EUROLAB laboratory provides testing and compliance services within the scope of ASTM F 2119 standard. This test method provides a quantitative measure of the image artifact produced under a standard set of scanning conditions. This test method applies only to passive implants designated MR-Safe or MR-Conditional.
This test method characterizes the distortion and signal loss artifacts produced by a passive implant (implant operating without an electrical or external power supply) in a magnetic resonance (MR) image. Anything not designated as MR-Safe or MR-Conditional is excluded.
Values stated in SI units should be accepted as standard. No other units of measurement are included in this standard.
ASTM F 2119 Test Purpose
Standard ASTM F 2119 describes a test method for measuring the extent of a susceptibility artifact based on a passive implant sample. A pixel in an image is considered part of image artifact if the intensity is changed in the presence of a test object by at least 30% compared to a reference image without the test object (reference value).
Standard ASTM F 2119, four test objects are scanned parallel and perpendicular to the main magnetic field and the greatest susceptibility artifacts are measured using two reference value determination methods (reference image-based and histogram-based reference value).
A standardized method can be applied for a rapid, objective and reproducible assessment of susceptibility artifacts. The result of the histogram-based method is not significantly different from the ASTM-compliant method.
Eurolab laboratory provides fast and reliable testing services within the scope of ASTM F 2119 standard.
