摘要
The invention is directed to a method, an instrument and a system for performing verification measurements and corrections of magnetic fields in magnets for Nuclear Magnetic Resonance imaging machines. According to the invention, test elements are used whereof Nuclear Magnetic Resonance images are detected. Then, these actually detected images are compared with the theoretical images which would be obtained in ideal conditions. The number, magnitude and position of correcting magnetic charges are determined from the differences between the actual image and the theoretical image. The invention is also directed to a specific test element and to a Nuclear Magnetic Resonance imaging machine.
