Abstract: An ultrasound diagnostic device includes a plurality of channels configured to receive data and a scan line data forming unit including a plurality of sub-scan line data forming groups and a data summing unit. The sub-scan line data forming group forms partial data of scan lines, and the data summing unit forms scan line data of the scan lines by summing the partial data. The sub-scan line data forming group includes a plurality of sub-scan line data forming units for forming the partial data of the scan lines by using the receiving data and providing a transmission path of the receiving data. First data lines transmit the receiving data between at least one of the sub-scan data forming unit and the channels, and second data lines transfer the receiving data between the sub-scan line data forming units.

Abstract: A method and apparatus for measuring the elastic characteristics of a medium by estimating variations in the speckle patterns in ultrasound images. The method for measuring the elastic characteristics of a medium comprises the steps of applying vibrations to the medium; acquiring a plurality of ultrasound image frames of the medium; estimating a variation in brightness of the speckle pattern over the plurality of ultrasound image frames; and measuring the elastic characteristics of the medium based on the estimated brightness variation. The apparatus for measuring the elastic characteristics of a medium comprises a vibrator for applying vibrations to the medium; transducers for acquiring a plurality of ultrasound image frames of the medium; a device for estimating a variation in brightness of a speckle pattern over the plurality of ultrasound image frames; and a device for measuring the elastic characteristics of the medium based on the estimated brightness vibration.

Abstract: An ultrasound imaging system using a knowledge-based image adjusting device, which enables to obtain the optimal ultrasound image by automatically adjusting image parameters on the basis of pre-stored patient information so that operating procedures required of a system operator are reduced. The ultrasound imaging system comprises a patient information recording medium; a reference image database for storing reference image parameters; a similarity calculation unit for comparing patient information and corresponding reference image parameters and determining the parameter with the highest similarity; and an image adjusting block for selecting a type of probe and automatically adjusting image settings of the selected probe. The ultrasound imaging system further comprises a user input device for inputting and adjusting degrees of freedom parameters.

Abstract: By using a novel structure of a beamformer which produce data for multiple receive scanlines in a time multiplexed manner, the size of the delay memory is reduced. An ultrasound receive beamforming apparatus for processing signals received from an array of transducers, comprises: a plurality of beamforming devices for applying delays to data samples of M channels. Each of said beamforming devices includes: a predetermined number of per-channel delay elements which provide first delays to the data samples of M channels, to provide delayed data per each channel and per each receive beam, first adders for adding the delayed data of not less than 2 channels provided from the per-channel delay elements, and multi-channel delay elements which provide second delays to the outputs of the first adders.
