A feasible and
practical design for a low-cryogen, high performance, head-only 7T MRI scanner
was completed. Construction of that system is underway and is expected to be
completed by the end of 2021 to generate first images.

Proposed C7T magnet showing the 8-coil configuration, cold heads, and helium
tanks. The size of the C7T relative to an average person is also shown for
scale. (b) One of the 2 large main coils being wound with superconducting NbTi
wire.

imaging performance at different b-values showing (a) diffusion TE time, and
(b) diffusion pulse width (d) for gradient configurations of whole-body
7T, C3T, C7T, and MAGNUS. The
performance improvement between the C7T gradient and the whole-body 7T is
clear.
