  • Patent number: 8951198
    Abstract: A first ultrasound pulse is applied to biological tissue to create shear waves in the biological tissue, a focused ultrasound pulse is transmitted into the biological tissue, one or more ultrasound signals is received from the biological tissue, and shear waves are detected in the biological tissue based on the received one or more ultrasound signals. At least one propagation property associated with the detected shear waves is determined, and the determined at least one propagation property is displayed. A strain image is obtained by either acoustic radiation forces or mechanical compression, e.g., by an ultrasound probe. The strain image is then converted to a new shear wave velocity image by using a previously-obtained shear wave velocity image.

  • Publication number: 20150032001
    Abstract: In tomographic image data, a reference region-setting unit (30) sets a body reference region for the body of a fetus and sets a cardiac reference region for the heart of the fetus. A body shift analysis unit (50) analyzes the movement of the fetus' body in the tomographic image data using the body reference region and obtains body shift information. A cardiac motion analysis unit (60) analyzes the movement of the fetus' heart in the tomographic image data using the cardiac reference region and obtains cardiac motion information. Once body shift information and cardiac motion information are obtained in this manner, a pulse information-processing unit (70) obtains fetal pulse information on the basis of the cardiac motion information from which the body shift information has been subtracted. The pulse information obtained by the pulse information-processing unit (70) is displayed on the display unit (80).

  • Publication number: 20150025386
    Abstract: In order to provide technology for limiting the deterioration of hardware in a portable diagnostic ultrasound apparatus without increasing user workload, internal processing of the portable diagnostic ultrasound apparatus is controlled according to the opening or closing of the cover case in which the monitor is disposed. In particular, when the cover case is closed, not only is output of ultrasonic waves stopped but processing that is being executed inside the apparatus is appropriately terminated and the power is turned off. When so doing, processing that is being executed is interrupted and cancelled and processing that is waiting to be executed is cancelled. The cancelled information is stored in a storage device.

  • Publication number: 20150016744
    Abstract: In ultrasound images, there are many stationary echoes in the region superficial to the deep region comprising the heart. In the present invention, a HPF processing unit (20) filters frame data by applying a high pass filter, the characteristics of which have been set according to the depth in the frame, on the frame data at said depth. The high pass filter can be achieved, for example, with a digital filter and the characteristics of the high pass filter are adjusted by the filter-setting unit (22) setting the filter coefficient of said digital filter. That is to say, the filter coefficient in the HPF processing unit (20) is controlled by the filter-setting unit (22) so that the deeper the region, the higher the offset level is set.

  • Publication number: 20140358003
    Abstract: In the diagnostic ultrasound apparatus, moving average processing is successively performed on a frame series with frame sets obtained from three kinds of frames, A, B, and C, as units, thereby successively generating compound frames. Each compound frame has a central sub-region and multiple peripheral sub-regions. In order to match the gain between the multiple sub-regions when generating each compound frame, a special compounding condition is applied to individual peripheral sub-regions. Specifically, processing that redundantly substitutes the same data value for multiple elements in the compounding computation equation is performed. Using such a spatial compounding, differences in gain between multiple sub-regions can be eliminated or reduced.

  • Patent number: 8845540
    Abstract: A 2D array transducer (10) is separated into a plurality of sub-arrays. Four representative sub-arrays SA1 to SA4 are shown in an enlarged manner. In addition, the 2D array transducer (10) is segmented into a plurality of transducer regions. Four regions of (I)-(IV) segmented by dot-and-chain lines represent four transducer regions. A grouping process is executed for each sub-array to group the plurality of transducer elements belonging to the sub-array into a plurality of element groups. In this process, for each transducer region, a common grouping pattern is set for the plurality of sub-arrays belonging to the transducer region. For example, because sub-arrays SA1 and SA2 belong to the same transducer region (IV), a common grouping pattern is set for the sub-arrays SA1 and SA2.
