The Mechanics of MRI

Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic technique for examining the anatomical structure (morphology) of living tissue. An MR system includes a number of major components in addition to the main magnet. The main magnetic field is shimmed or adjusted with shim resonators, modified for imaging though the addition or subtraction of a gradient field with gradient resonators, and the patient is “examined” by the application of a tuned RF magnetic field from an RF resonator to produce the conditions necessary for the production of an MR image or spectrum. Ceresensa is focused on the design and manufacture of RF resonators, which are arguably the first determinant of quality in MRI.
