A method for postural independent location of targets in diagnostic images acquired by multimodal acquisitions, compensating for deformation of soft tissues due to changing posture, includes generating a transition of a digital image of the inside of a target region from a first to a second position by correlating the position of markers placed on the external surface of the target region in a digital image of the inside of the target region and in a digital representation of the external surface of the target region acquired by optically scanning the external surface; and at a later time registering the diagnostic image of the inside of the target region, transitioned into the second position, with a diagnostic image of the same target region acquired with the target region in the second position by matching a second representation of the external surface of the target region in the second position without markers with the diagnostic image of the inside of the target region transitioned into the second position.

During a focused-ultrasound or other non-invasive treatment procedure, the motion of the treatment target or other object(s) of interest can be tracked in real time based on (i) the comparison of treatment images against a reference library of images that have been acquired prior to treatment for the anticipated range of motion and have been processed to identify the location of the target or other object(s) therein and (ii) complementary information associated with the stage of the target motion during treatment.

In an embodiment, a method for effecting thermal therapy using an in vivo probe includes positioning the probe in a volume in a patient, identifying an irregularly shaped three-dimensional region of interest and automatically applying thermal therapy to the region using the probe. Applying thermal therapy may include identifying a first emission level at a first rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission of the probe, causing rotation of the probe to a next rotational angle, identifying a next emission level at the next rotational angle based in part on a depth of a radial portion of the region in the direction of probe emission, activating emission to deliver therapeutic energy, and repeating rotation and emission until therapeutic energy has been delivered to the volume.
