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.
