Abstract
Systems and methods using magnetic resonance imaging for monitoring the temperature of a tissue mass being heated by energy converging in a focal zone that is generally elongate and symmetrical about a focal axis. A first plurality of images of the tissue mass are acquired in a first image plane aligned substantially perpendicular to the focal axis. A cross-section of the focal zone in the first image plane is then defined from the first plurality of images. A second plurality of images are acquired of the tissue mass in a second image plane aligned substantially parallel to the focal axis, the second image plane bisecting the first image plane at approximately a midpoint of the defined focal zone cross-section.
