Abstract
A magnetic resonance imaging (MRI) system includes a computer for performing overall control and signal processing, a pulse generator for generating a predetermined RF pulse signal and a gradient field pulse signal having variable intensities, a main magnet for generating a static magnetic field, a gradient field coil having a cylindrical dish-like structure surrounding a magnetic pole of the main magnet for generating a gradient field based on the gradient field pulse signal, an RF coil for transmitting a RF field according to the RF pulse signal to an imaging object and receiving MR signals from the imaging object, and an analog-to-digital converter for converting the MR signals from the RF coil into digital signals and outputting the converted digital signals to the computer. The influence of the reverse magnetic field generated from the reverse circulation portion of the gradient field coil is reduced whereby the linear gradient field region and an image region thereof are enlarged, and gradient field coils can be attached stably to magnetic poles whereby vibration and noise are reduced.
