1. A method comprising:
performing thermal therapy on an intended area located within a first anatomical region of interest, while limiting heating to an unintended area of a second anatomical region of interest; and
performing an interleaved acquisition, during the thermal therapy, of a first set of slabs in a first 3D volume that covers the first anatomical region of interest using a first set of sampling characteristics and a second set of slabs in a second 3D volume that covers the second anatomical region of interest using a second set of sampling characteristics, the first set of sampling characteristics including a first thickness parameter and the second set of sampling characteristics including a second thickness parameter,
wherein the first and second 3D volumes do not overlap; and
wherein the second thickness parameter for the second set of slabs covering the unintended area is greater than the first thickness parameter for the first set of slabs.
