摘要:
Automated determination and setting of an ultrasound system transmit power level is provided for contrast agent imaging. Low mechanical index imaging of contrast agents allows substantially continuous imaging of contrast agents without destruction. By comparing data associated with different transmit power levels, different delays between acquisition or different acquisition sequences, a contrast agent imaging transmit power generally minimizing destruction of contrast agents and maximizing signal-to-noise ratio is automatically determined.

A diagnostic medical ultrasound system having an integrated invasive medical device guidance system is disclosed. The guidance system obtains image slice geometry and other imaging parameters from the ultrasound system to optimize the guidance computations and visual representations of the invasive medical device and the imaged portion of the subject. Further, the ultrasound system obtains guidance data indicating the relative location, i.e. position and/or orientation of the invasive medical device relative to the transducer and imaging plane to optimize the imaging plane and ultrasound beam characteristics to automatically optimally image both the imaged portion of the subject and the invasive medical device.

An apparatus for tethering elongated members, such as cables, tubes and the like, to a human body, is disclosed. The tether is configurable to attach to various human appendages and includes an embodiment that is strong enough to support a heavy cable, such as a hospital ultrasound equipment cable. The tether can further accommodate various diameters of cables, tubes, cords and the like, including writing implements, and can be comprised of various alternative substances, including semi-rigid, soft and non-allergenic materials. A critical aspect of the present invention is that the cable, tube, cord and the like be quickly releasable from the body by tugging the cable, tube, cord and the like.

摘要:
An ultrasonic imaging method includes activating a transmit aperture within a multi-element transducer array, transmitting one or more ultrasonic beams along scan direction(s) that span the region of interest, for each transmit event, receiving ultrasound echoes from each element of a receive aperture, grouping the receive channel echo data into two or more sets corresponding to different receive sub-apertures, combining each sub-aperture data set to generate partially focused echo-location data for one or more reconstruction lines, and storing all the sub-aperture echo data sets during a storage period in a format that can be retrieved for later analysis. A method includes, during a post-storage period, retrieving stored sub-aperture data, combining the sub-aperture data to form one or more selected reconstruction lines, processing echo data to extract motion information from one or more sample positions along the selected reconstruction lines, and displaying an image representative of the processed motion information.

摘要:
An ultrasound image is morphed for perfusion assessment. Various images within a sequence of images or movie clip are mapped to one frame of reference using local warping. Nonlinear local image transformations or other warping based on local estimates of motion are used to interpolate different images to the common reference. The elastic stretching and compression of local image data results in a sequence of images where the same spatial location in each image represents the substantially same spatial location of the imaged tissue. The organ, tissue or region of interest is stationary throughout the sequence of images.
