no. 1 approach

[0028] Hereinafter, a first embodiment will be described with reference to the drawings. In addition, in the following description, the same code|symbol is attached|subjected to the structural unit which has substantially the same function and structure, and it repeats description only when necessary.

[0029] figure 1 A block configuration diagram of the ultrasonic diagnostic apparatus 1 according to the present embodiment is shown. As shown in the figure, this ultrasonic diagnostic apparatus 1 includes an ultrasonic probe 12, an input device 13, a monitor 14, an ultrasonic transmitting unit 21, an ultrasonic receiving unit 22, a B-mode processing unit 23, a Doppler processing unit 24, and a scan converter. 25. A speckle removal processing unit 26, a control processor (CPU) 28, an internal storage unit 29, and an interface unit 30. Hereinafter, the function of each structural unit is demonstrated.

[0030] The ultrasonic probe 12 has a plurality of piezoelectric vibrators ...

no. 2 approach

[0071] In the first embodiment, an example of performing speckle removal processing on two-dimensional image data (RAW data) was shown. In contrast, the ultrasonic diagnostic apparatus 1 according to the present embodiment will describe a case where speckle removal processing is performed on three-dimensional volume data (RAW data).

[0072] Figure 9 It is a diagram showing the configuration of the ultrasonic diagnostic apparatus 1 according to the present embodiment. if with figure 1 In comparison, there is a difference in that the volume data generation unit 31 is further provided, and that the speckle removal processing unit 26 performs speckle processing on the volume data from the volume data generation unit 31 .

[0073] The volume data generation unit 31 generates B-mode volume data using the B-mode image data received from the B-mode processing unit 23 . Furthermore, the volume data generation unit 31 generates Doppler mode image volume data using the Doppler mode ...

no. 3 approach

[0080] In the second embodiment, an example in which the speckle removal process according to the first embodiment is performed on B-mode volume data before three-dimensional image processing is shown. In contrast, the ultrasonic diagnostic apparatus 1 according to the present embodiment will describe a case where speckle removal processing is performed on image data after three-dimensional image processing.

[0081] Figure 11 It is a diagram showing the configuration of the ultrasonic diagnostic apparatus 1 according to the present embodiment. if with Figure 9 In comparison, the speckle removal processing unit 26 is different in that the speckle processing is performed on the image data from the three-dimensional image processing unit 32 .

[0082] Figure 12 It is a diagram showing an example of a method of simultaneously displaying a plurality of three-dimensional images (volume rendering image 14 a , first multi-section transformed display image 14 b , and second mult...

Abstract

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.

Description

[0001] This application is based on and claims priority from Japanese Patent Application No. 2010-176733 filed on August 5, 2010, the entire contents of which are hereby incorporated by reference. technical field [0002] The present invention relates to an ultrasonic diagnostic device and an ultrasonic image processing device. Background technique [0003] Ultrasonic diagnosis can display the beating of the heart or the movement of the fetus in real time through a simple operation of bringing the ultrasonic probe into contact with the body surface, and it can be repeatedly inspected because of its high safety. In addition, the scale of the system is small compared with other diagnostic equipment such as X-ray CT and MRI, and it can be said that it is a simple diagnostic method that can easily perform examinations that are moved to the bedside. Ultrasonic diagnostic devices used in this ultrasonic diagnosis vary in various ways depending on the types of functions they posses...
