Problems solved by technology

[0009] However, in the technique disclosed in International Publication No. 2010 / 044385, the display is optimized within a given ROI, and therefore, the viewing in the overall distribution of hardness is different from the local distribution of hardness
In addition, the technology disclosed in International Publication No. 2005 / 025425 includes processing according to various thresholds or processing based on experimental results, and therefore, there is a result display of the identification process of the viscoelastic coefficient itself that may mislead the interpretation of a person as an inspector ( interpretation)

[0039] Configuration Example of Ultrasonic Image Diagnosis Device

[0040] figure 1 is a block diagram showing a configuration example of an ultrasonic image diagnosis apparatus as an ultrasonic processing apparatus to which the present technology is applied.

[0041] figure 1 The illustrated ultrasonic image diagnosis apparatus 11 is an apparatus that captures the inside of a target (subject) using ultrasonic waves and displays an image (ie, an ultrasonic image). For example, the ultrasonic image diagnostic apparatus 11 can be used medically to photograph the inside of a patient's body or a fetus, or directly applied to an organ or tissue surgically, and industrially can be used to photograph a cross-section inside a product.

[0042] Specifically, the ultrasonic image diagnosis apparatus 11 takes an ultrasonic image of a target using ultrasonic waves, and displays an image related to a viscoelastic coeffi...

Abstract

An ultrasonic processing apparatus includes a viscoelastic coefficient calculation unit that calculates a viscoelastic coefficient of an object from an ultrasonic signal acquired through an oscillator of a probe; and a spatial change amount calculation unit that calculates spatial change amount of the viscoelastic coefficient calculated by the viscoelastic coefficient calculation unit and outputs the calculated spatial change amount as brightness information when displaying an image relating to the viscoelastic coefficient.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Japanese Priority Patent Application JP2013-133668 filed on June 26, 2013, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a sonication device and a sonication method, and in particular to a sonication device and a sonication method by which hardness differences in elastography can be depicted. Background technique [0004] In elastography, which uses ultrasound to estimate tissue stiffness, color information (hue of the HSV color system) is mainly used to represent parts that have different stiffness and are distributed in the tissue. [0005] However, if the difference in hardness of each part is small, there is a difficulty in sufficiently detecting the difference in hardness by human vision in an expression using color. [0006] In order to differentially delineate parts with small differences, a sys...
