title: Protocols and test objects for the assessment of MRI equipment. EEC Concerted Research Project.
abstract: As part of the European Economic Community research project, a set of five test objects for the assessment of magnetic resonance imaging systems has been designed and constructed and protocols for their use developed. This paper presents design details of the test objects and the protocols for their use to allow the measurement of image uniformity, image signal-to-noise ratio, geometric distortion, slice profile, width and position, spatial resolution, and T1 and T2 precision and accuracy.
