The design of a fMRI magnet for the study of the human motor cortex poses a number of challenges due to the necessity of maintaining the subject in a natural, erect position, with free access to the environment. One way of meeting the challenge is to center the design around a three-dimensional finite configuration containing a closed cavity where the field is homogeneous. When the cavity is open to allow patient access a strong gradient arises that needs to be compensated without compromising the structure efficiency.
