Embodiment approach 1

[0039] figure 1 It is a block diagram showing the configuration of the ultrasonic observation system 1 including the ultrasonic observation device 3 according to Embodiment 1 of the present invention. The ultrasonic observation system 1 shown in the figure includes: an ultrasonic endoscope 2 (ultrasonic probe) which transmits ultrasonic waves to an object to be observed and receives ultrasonic waves reflected by the object; An ultrasonic image is generated based on the ultrasonic signal acquired by the ultrasonic endoscope 2 ; and a display device 4 that displays the ultrasonic image generated by the ultrasonic observation device 3 .

[0040] The ultrasonic endoscope 2 has an ultrasonic vibrator 21 at its distal end, and the ultrasonic vibrator 21 converts an electric pulse signal received from the ultrasonic observation device 3 into an ultrasonic pulse (acoustic pulse) and then irradiates the subject, The reflected ultrasonic echo is converted into an electrical echo signa...

Abstract

This ultrasonic observation device transmits ultrasonic waves to an object being observed and generates an ultrasonic image on the basis of an ultrasonic signal acquired by an ultrasonic probe provided with an ultrasonic oscillator which receives the ultrasonic waves reflected by the object. The ultrasonic observation device is provided with: a frequency analysis unit for calculating a plurality of frequency spectra by analyzing the frequency of a signal generated on the basis of the ultrasonic signal; a comparison unit for comparing a physical quantity based on the ultrasonic waves reflectedby the object with a threshold value set corresponding to the physical quantity; and a characteristic amount calculation unit for calculating a frequency characteristic amount on the basis of the frequency spectra calculated by the frequency analysis unit and the comparison result by the comparison unit.

Description

technical field [0001] The present invention relates to an ultrasonic observation device for observing tissue of an observation object by using ultrasonic waves, a working method of the ultrasonic observation device, and a working program of the ultrasonic observation device. Background technique [0002] Conventionally, a technique is known in which, in an ultrasonic observation device for observing tissue of an observation target using ultrasonic waves, a feature quantity of a frequency spectrum of an ultrasonic signal having a characteristic corresponding to a tissue property is calculated, and the feature quantity is generated based on the feature quantity. Feature image for identifying tissue properties. In this technique, after acquiring a frequency spectrum by analyzing the frequency of a received ultrasonic signal, an approximate expression of the frequency spectrum within a predetermined frequency band is calculated, and a feature quantity is extracted from the appr...
