摘要： An ultrasonic diagnostic apparatus comprises a first reception echo obtaining unit, a second reception echo obtaining unit, a reception echo combining unit, and an image generating unit. The first reception echo obtaining unit transmits a plurality of ultrasonic pulses having frequency spectra different from one another to an object, and obtains each of reception echoes corresponding to the plurality of ultrasonic pulses. The second reception echo obtaining unit transmits an ultrasonic pulse having the same frequency component characteristics as an combined pulse obtained by combining the plurality of ultrasonic pulses, and to obtain an reception echo. The reception echo combining unit combines the reception echoes obtained by the first reception echo obtaining unit and the reception echo obtained by the second reception echo obtaining unit to generate a combined signal. The image generating unit generates an image of echoes reflected from the object on the basis of the combined signal.

摘要： According to one embodiment, an ultrasonic diagnostic apparatus comprises a decomposition unit, a filtering unit, a level control unit and a mixing unit. The decomposition unit hierarchically performs multi-resolution decomposition of the ultrasonic image data and acquires low-frequency decomposed image data with first to n-th levels and high-frequency decomposed image data with first to n-th levels. The filtering unit calculates a filter coefficient using the high-frequency decomposed image data and uses the filter coefficient to perform nonlinear anisotropic diffusion filtering on the low-frequency decomposed image data or output data and generate edge information on a signal. The control unit controls a signal level of the high-frequency decomposed image data. The mixing unit acquires ultrasonic image data by hierarchically performing multi-resolution mixing of output data of the filtering unit or output data from a next lower layer and output data of the high-frequency level control unit.
