no. 1 Embodiment approach

[0039] figure 1 It is a block diagram showing the overall configuration of the ultrasonic diagnostic apparatus according to the first embodiment. This ultrasonic diagnostic apparatus generates a tomographic image of tissue on a tomographic plane of a subject using ultrasonic waves, and obtains elasticity information indicating the hardness or softness of the tissue to generate an elasticity image.

[0040] like figure 1 As shown, the ultrasonic diagnostic apparatus 100 includes: an ultrasonic probe 12 that is used in contact with a subject; a transmitting unit 14 that repeatedly transmits ultrasonic waves to the subject via the ultrasonic probe 12 at time intervals; a receiving unit 16 that It receives the time-series reflected echo signal generated from the subject; the ultrasonic transceiver control unit 17 controls the transmitting unit 14 and the receiving unit 16; the phase adjustment adding unit 18 adjusts the phase of the received reflected echo After the phase adju...

no. 2 Embodiment approach

[0084] Image 6 It is a block diagram showing the overall configuration of the ultrasonic diagnostic apparatus according to the second embodiment of the present invention. The second embodiment differs from the first embodiment in that the memory 38 is not provided, and the evaluation image generation unit 50 has a statistical processing unit. Since other parts are the same as the first embodiment, redundant descriptions are omitted. In addition, although the case where the memory 38 was not provided was exemplified in 2nd Embodiment, the memory 38 may be provided.

[0085] Figure 7 It is a figure which shows the structure of the image generation part 50 for evaluation of this embodiment. like Figure 7 As shown, the evaluation image generation unit 50 includes a histogram calculation unit 52 that generates a diagnostic image based on the elasticity frame data output from the elasticity information calculation unit 32 as an evaluation image for evaluating the disease degre...

Abstract

Provided is an ultrasonic diagnostic device provided with: an ultrasonic probe which transmits and receives ultrasonic waves to and from a subject; a reception processing means which receives a reflection echo signal measured by the ultrasonic probe and generates RF signal frame data relating to a cross-sectional plane of a part to be diagnosed of the subject; a displacement measurement means which on the basis of a pair of RF signal frame data having different states of pressing against the tissue of the cross-sectional plane, measures the displacements of the tissue at a plurality of measurement points of the cross-sectional plane and generates displacement frame data, an elasticity information calculation means which on the basis of the generated displacement frame data, calculates elasticity information indicating the hardness or softness of the tissue at the plurality of measurement points of the cross-sectional plane and generates elasticity frame data; a means for generating image for evaluation which generates, as an image for evaluation for evaluating the degree of a disorder of the part to be diagnosed of the subject, histograms of the displacements and / or the elasticity information of the tissue at the plurality of measurements points of the cross-sectional plane at different times; and an image display which displays the histograms generated at the different times.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic apparatus, a method for generating an image for disease evaluation of an object to be diagnosed, and a program for generating an image for evaluating a disease of an object to be diagnosed. Quantitative techniques using images for the evaluation of disease extent. Background technique [0002] Ultrasonic diagnostic equipment transmits ultrasonic waves to the inside of the subject through an ultrasonic probe equipped with a plurality of ultrasonic transducers, and receives reflected echo signals corresponding to the structure of biological tissues from the inside of the subject. The wave signal generates a tomographic image such as a B-mode image to be displayed for diagnosis. [0003] In recent years, as described in Patent Document 1, by manually or mechanically, an ultrasonic probe is used to compress a subject while measuring an ultrasonic reception signal (RF signal), thereby generating an ...
