Bibliography of MRI
Bibliography of MRI AC - Alternating Current is a continuously changing flow of electrons that alternates its polarity at a periodic rate. ACQUISITION - the process of measuring and storing image data. ACQUISITION MATRIX - the total number of independent data samples in the frequency (f) and phase (f) directions. ACQUISITION TIME - the period of time required to collect the image data. This time does not include the time necessary to reconstruct the image. ADC - analog-to-digital converter ALIASING (WRAP AROUND ARTIFACT) - the phenomenon resulting from digitizing fewer than two samples per period in a periodic function. Aliasing can occur in MR imaging whenever the area of anatomy extends beyond the field of view. These areas extending beyond the field of view boundaries are aliased back into the image to appear at artifactual locations. ALTERNATING CURRENT (AC) - a current that continuously changes in magnitude and direction...
