Evaluation of the performance parameters are needed to assure proper system performance and represent a valuable source of qualitative and quantitative data for routine quality control testing. The performance parameters that require regular evaluation in magnetic resonance imaging systems are discussed here. These parameters include the Resonance frequency, Magnetic field homogeneity, Image uniformity, spatial resolution, S/N ratio; Gradient linearity, Standard reference measurement, 1st & 2nd Echo artifacts and Echo intensities for spin echo measurements. The aim of the quality assurance is to detect deviations in the performance of the equipment well before they actually show up in the clinical images in the form of image artifacts or degraded images.
