Medical imaging has been widely used in modern medicine for diagnosis, which makes doctors very helpful in diagnosing diseases. However, Magnetic Resonance Imaging (MRI) has played an important role in medical imaging, providing a safer and more precise imaging method than X-RAY. The main content of the industry-university cooperation plan between National Taipei University of Technology, and Kwan Chiu Radio MFG Co., Ltd. is to research and develop an MRI platform for animals.

In the target field method, Ampere's law is reversed to calculate the required current directly from the specification of the required field change. Target field methods have been the most popular gradient coil design methods because of their ease of computation in determining suitable wire patterns. The desired (or target) magnetic field is specified on a cylindrical surface within a cylindrical gradient coil. Calculate the current distribution on the gradient coil surface to achieve the target magnetic field. Also in theoretical development, the inductance in terms of current distribution is minimized according to the magnetic flux density and the desired field distribution in the region of interest (ROI).
