Characteristics of MR-tomographers' image and their monitoring.

Abstract

Similar to X-ray computer tomography and taking into account the specificity of obtaining the MR image a range of characteristics is proposed for the control of the MR tomographers' images. On the basis of the literature analysis and our own research requirements are formulated to the range and the errors of the MR image characteristics guaranteeing the required diagnostics reliability level. Proceeding from the requirements to the MR image characteristics the requirements are formulated to test objects for their monitoring, including the MR-contrast media for test objects. The test objects' structures are described, developed in accordance with the formulated requirements.
