摘要： A technique for measuring and characterizing the motion of an internal organ is provided. The technique includes using two or more motion-sensitive sensors, disposed on a patient in a region of interest proximate to the internal organ, which acquire motion data along the surface of the patient. The motion data may then be processed and displayed to depict or characterize the mechanical motion undergone by the internal organ. The mechanical motion may be displayed as an image or video. In addition, the mechanical motion data may be combined with other measured data, such as electrical or acoustic data, or with images acquired by other imaging modalities to generate a composite image.

摘要： One or more techniques are provided for determining the overall motion of an organ of interest relative to a viewer or imager. Motion data is acquired for the organ of interest and/or for one or more proximate organs using sensor-based and/or image data-based techniques. The sensor-based techniques may include electrical and non-electrical techniques. The image data-based techniques may include both pre-acquisition and acquisition image data. The motion data for the organ of interest and proximate organs may be used to determine one or more quiescent periods corresponding to intervals of minimal motion for the organ of interest and the proximate organs. The one or more quiescent periods may be used to determine one or more gating points that may be used prospectively, i.e., during image acquisition. In addition, the one or more quiescent periods may be used to determine one or more motion compensation factors that may be used during processing and reconstruction of the acquired image data. The gating points and motion compensation factors may be used, separately or together, to reduce motion-related artifacts in the reconstructed images.

摘要： One or more techniques are provided for measuring the motion of an organ in three dimensions. As provided by the technique, the motion of the organ along each dimension may be determined by a suitable methodology. Where sensor-based motion measurements are suitable, one or more sensors may be placed on a patient to measure internal motion of the organ of interest along one or more perpendicular axes. Where image-based techniques are suitable, the motion of the internal organ along a perpendicular axis may determined using pre-acquisition image data or acquisition image data when suitable. Concurrent motion vectors for all three dimensions may be obtained from the motion data acquired for the perpendicular axes by the disparate methodologies. The concurrent motion vectors may be combined to describe the three-dimensional motion of the organ over time. Validation of the motion data may be performed for each of the one-dimensional motion data sets using motion data acquired by image-based methods, or other image-based methods, for a respective axis.
