Problems solved by technology

[0005] In addition, when the displacement occurs due to the body movement of the subject, or when the shear wave is reflected / refracted in the tissue, etc., the hardness of the living tissue may not be accurately measured
In such a case, the hardness image visualized by the elastography method becomes an image with low reliability

no. 1 Embodiment approach

[0032] First, the configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a block diagram showing a configuration example of the ultrasonic diagnostic apparatus according to the first embodiment. Such as figure 1 As shown, the ultrasonic diagnostic apparatus 10 according to the first embodiment has an apparatus main body 100 , an ultrasonic probe 101 , an input device 102 , and a monitor 103 .

[0033] The ultrasonic probe 101 has a plurality of vibrators (for example, piezoelectric vibrators), and these vibrators generate ultrasonic waves based on drive signals supplied from a transmission unit 110 included in the device main body 100 described later. In addition, the plurality of vibrators included in the ultrasonic probe 101 receives reflected waves from the subject P and converts them into electrical signals. In addition, the ultrasonic probe 101 has a matching layer provided on the vibrator, a backing mate...

no. 2 Embodiment approach

[0105] In the first embodiment, a case was described in which pixel values ​​corresponding to the arrival times are assigned to the line image data 20 , but the embodiment is not limited to this. For example, the ultrasonic diagnostic apparatus 10 may assign pixel values ​​corresponding to other parameters to the line image data 20 . In view of this, in the second embodiment, a case where the ultrasonic diagnostic apparatus 10 assigns pixel values ​​corresponding to other parameters to the line image data 20 will be described.

[0106] Figure 7 It is a block diagram showing a configuration example of the ultrasonic diagnostic apparatus 10 according to the second embodiment. The ultrasonic diagnostic apparatus 10 according to the second embodiment is equipped with figure 1 The illustrated ultrasonic diagnostic apparatus 10 has the same configuration, but differs from a part of the processing of the line image generation unit 172 in that it further includes the calculation un...

no. 3 Embodiment approach

[0122] In the first and second embodiments described above, the case where the line image data 20 is displayed using the arrival time was exemplified, but the embodiment is not limited to this. For example, the ultrasonic diagnostic apparatus 10 may display an image serving as a scale line such as the line image data 20 using other parameters. In view of this, in the third embodiment, a case will be described in which the ultrasonic diagnostic apparatus 10 displays an image serving as a scale line such as the line image data 20 using other parameters.

[0123] The ultrasonic diagnostic apparatus 10 according to the third embodiment is equipped with figure 1 The illustrated ultrasonic diagnostic apparatus 10 has the same configuration, but part of the processing of the line image generation unit 172 and the display control unit 173 is different. In view of this, in the third embodiment, the points different from the first embodiment will be described as the center, and for the...

Abstract

The present invention relates to an ultrasonic diagnostic device, an image processing device, and an image processing method capable of expressing the reliability of the hardness of living tissue on an ultrasonic image. The transmitting unit transmits from the ultrasonic probe the ultrasonic wave for generating displacement that displaces the living tissue based on the force of the acoustic radiation, and transmits the observation unit for observing the displacement of the living tissue in a predetermined scanning area generated by the ultrasonic wave for generating displacement from the ultrasonic probe. Use ultrasound. The receiving unit generates reflected wave data from reflected waves received by the ultrasonic probe. The image generation unit calculates the displacement of each of the plurality of positions in the scanning area at a plurality of time phases based on the reflected wave data, and determines the time phase at which the calculated displacement is approximately the largest at each of the plurality of positions, and generates a time phase for the plurality of positions. Image data in which the determined time phases are substantially the same as each other. The display control unit superimposes and displays an image based on the image data on the medical image corresponding to the area including the scanning area.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2013-258666 filed on December 13, 2013, and cites the entire content of the above-mentioned Japanese Patent Application in this application. technical field [0002] Embodiments relate to an ultrasonic diagnostic device, an image processing device, and an image processing method. Background technique [0003] Conventionally, elastography is known, which measures the hardness of living tissue and visualizes the distribution of the measured hardness. Elastography is used, for example, for diagnosing diseases such as liver cirrhosis in which the hardness of living tissue changes according to the degree of progression of the lesion. In the elastography method, a method of displacing a living tissue to evaluate hardness is roughly divided into the following two types. [0004] The first method is a method of visualizing the relative hardness from the magnitude of deformation at each point in the scann...
