Magnetic resonance imaging (MR) plays an important role in the diagnosis of the disease and the treatment of the patient. Quality control (QC) is a very important component of radiological practice. Well performed quality control enables the identification of problems and taking the right actions to solve them, with minimal outage. Quality assurance of clinical MR scanners is necessarily to obtain optimal images in hospital facilities. Computational imaging systems such as computed tomography (CT) and magnetic resonance imaging (MR) have specially designed quality control tests. In the United States, the American College of Radiology (ACR) has developed dedicated phantoms and quality control (QC) procedures for various imaging modalities. Most routine tests such as daily or weekly tests are performed by a radiology technologist, while semiannual and annual tests are performed by a medical physicist or service engineer. Daily quality control checks include a visual inspection of the entire scanner hardware, the functions of security and communication devices, and a general assessment of the image quality. Once a week, a special MR phantom is placed in the scanner and other measurements are recorded such as geometric accuracy, high contrast spatial resolution, layer thickness accuracy, layer position accuracy, image intensity uniformity, signal percentage determination and low contrast object detection.
