MR guided Focused Ultrasound (MRgFUS) is used to treat
noninvasively many brain disorders. Currently gradient
echo (GRE) is used for thermometry imaging using the PRF
shift. In this work we present a new thermometry
sequence which is based on Fast Spin Echo. It is shown
that this sequence is not sensitive to field
inhomogeneity, provides higher temperature signal to
noise ratio, and acquire 3 slices simultaneously during
heating.
