Web24 mei 2024 · An MRI scan does right evaluation of the heart and the aorta structure, where it can detect aneurysms or tears. The main part of an MRI machine is its tube-shaped or cylinder-shaped magnet. The magnet strength is measured in metric units called Tesla. Generally, most of the cylinder magnets have a strength ranging from .05 to 1.5 Tesla. WebFor MRI a time-varying radiofrequency (RF) field, commonly referred to as B 1, must be first transmitted into the spin system near the Larmor frequency. In addition to having specific frequency, the B 1 field must also be applied perpendicular to the main magnetic field ( B o ). The B 1 field is produced by driving electrical currents through ...
