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.
