Artifacts in nuclear magnetic resonance imaging

特許 権利維持 In medical imaging, artifacts are misrepresentations of tissue structures seen in medical images produced by modalities such as Ultrasonography, X-ray Computed Tomography, and Magnetic Resonance Imaging. These artifacts may be caused by a variety of phenomena such as the underlying physics of the energy-tissue interaction (i.e. Ultrasound-air), data acquisition errors (such as patient motion), or a reconstruction algorithm's inability to represent the anatomy. Physicians typically learn to recognize some of these artifacts to avoid mistaking them for actual pathology.
