    摘要: Feedback of position is provided for high intensity focused ultrasound. The location of a beam from a HIFU transducer is determined using ultrasound imaging. The ultrasound imaging detects tissue displacement caused by a beam transmitted from the HIFU transducer. The displacement or information derived from the displacement may be used to detect and image the location of the beam. Separate transducers may be used for HIFU and imaging. The user aims the HIFU transmissions with feedback from ultrasound imaging of displacement of tissue.

    摘要: Systems and methods are described for tracking motion in a medical imaging system. The methods use landmark sets including hard landmarks and soft landmarks. The systems can include means for generating a landmark set, means for constructing a landmark set spatial relationship, means for computing a context similarity measurement, means for cost function construction, and means for cost function minimization and motion estimation. The invention provides advantages because, among other reasons, the use of a cost function of two or more variables, where the cost function is defined over members of the landmark set collection, and the cost function subject to at least two constraints and the landmark set stability in terms of context similarity measurements and spatial relationship provide effective and robust motion tracking.

    摘要: A difference between a detected motion and a reference motion is automatically displayed. The reference motion is a modeled motion of an organ, a base line motion of an organ or another portion of an organ. A deviation in motion amplitude, angle or both angle and amplitude from a reference set may more easily identify abnormal or normal motion of the organ.
