[0028] First, the configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a diagram for explaining the overall configuration of the ultrasonic diagnostic apparatus according to the first embodiment. Such as figure 1 As shown, the ultrasonic diagnostic apparatus 1 according to the first embodiment includes an ultrasonic probe 10 , an input device 20 , a monitor 30 , and an apparatus main body 100 .
[0029] The ultrasonic probe 10 has a plurality of piezoelectric vibrators that generate ultrasonic waves based on drive signals supplied from an ultrasonic transmitting unit 110 included in the device main body 100 described later. In addition, the ultrasonic probe 10 receives a reflected wave signal from the subject P and converts it into an electric signal. In addition, the ultrasonic probe 10 has a matching layer provided on the piezoelectric vibrator, a backing material that prevents ultrasonic waves from propag...

[0085] In the above-mentioned first embodiment, the description has been made on the case where the noise signal is acquired in real time. In the second embodiment, the case where the information of the noise signal is acquired in advance and the information of the noise signal is read out when extracting the low S / N region will be described. In addition, in the second embodiment, with Figure 4 The control unit 170 according to the first embodiment shown has the same configuration. In the second embodiment, a control unit that reads out noise signal information when extracting a low S / N region will be described as the signal acquisition unit 171a. That is, the signal acquisition unit 171a is for Figure 4 The signal acquisition unit 171 shown has a new processing component added.
[0086] The signal acquisition unit 171 a acquires noise signal information corresponding to the current ultrasonic transmission / reception condition from the storage unit 180 that stores noise si...

[0096] In addition, the first and second embodiments have been described so far, but it can also be implemented in various forms other than the above-mentioned first and second embodiments.
[0097] (1) Modification 1
[0098] In the above-mentioned first and second embodiments, the case where this method is used in the analysis of the tissue characteristics based on the attenuation amount of the ultrasonic signal has been described. In Modification 1, a case where this method is used in the analysis of tissue properties based on the probability density distribution of the signal intensity of the ultrasonic signal will be described. Specifically, a case where this method is applied to a method that calculates a probability density distribution curve based on the signal strength of a received signal received from a diagnosis area and compares it with a theoretical value when the diagnosis site is normal will be described. Probability density distribution curves (for example, R...
