    摘要: The invention provides a technique for acquiring subsequent image data in a medical diagnostic context based upon analysis of initial image data. The initial image data is processed via a computer aided diagnosis algorithm to determine whether additional image data acquisition is appropriate. Subsequent acquisition processes may be performed on the same imaging system from which the initial image data originated, or a different imaging system. The imaging systems may also be of different modalities. The subsequent acquisition of image data may be performed automatically without operator intervention, or the prescribed subsequent acquisition sequence may be outputted by the system for execution upon command of an operator.

    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: 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 identifying a period of minimal motion for an organ of interest, such as the heart or lungs. Motion data is acquired for the organ of interest and for one or more proximate organs using sensor-based and/or image-based techniques. The sensor-based techniques may include electrical and non-electrical techniques. The image-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 generate a set of multi-input motion data that may be processed to identify desired periods, such as periods of minimal motion, within the overall motion of the organ of interest.

    摘要: A method and apparatus are provided for measuring a weak physiological signal in the presence of stronger signals. The method and apparatus utilize motion sensing devices placed on or about the patient to obtain a motion data set from each motion sensing device describing the aggregate detected motion. The data sets are synchronized and then used to solve a set of simultaneous equations which allows for the separation of the various motion components which may include such components of interest as fetal heart motion.
