Problems solved by technology

[0007] However, in conventional TIC analysis, there is a problem that if the position or orientation of the probe deviates due to vibration, etc., the region of interest on the scanning plane deviates from the set ROI, so the region of interest cannot be accurately grasped (evaluated) Variation of contrast brightness over time in
[0009] However, there is a problem that in order to perform TIC analysis, it is necessary to store volume data (moving images) acquired in each case in advance, resulting in an increase in data volume

no. 1 approach

[0023] First, use figure 1 The configuration of the ultrasonic observation device according to the first embodiment will be described. figure 1 It is a block diagram showing the overall configuration of the ultrasonic observation device according to the first embodiment. figure 1 The illustrated ultrasonic observation apparatus 1 is an apparatus for observing a specimen using ultrasonic waves.

[0024] The ultrasonic observation device 1 is configured to include: an ultrasonic probe 2 that outputs ultrasonic pulses to an object and receives ultrasonic echoes reflected by the object; Receiving; computing unit 4, which performs predetermined calculation on the electrical echo signal obtained by converting the ultrasonic echo; image processing unit 5, which generates image data corresponding to the electrical echo signal obtained by converting the ultrasonic echo; input unit 6. It is realized by using input devices (Japanese: インターフェース) such as a keyboard, a mouse, and a touc...

no. 2 approach

[0058] Next, a second embodiment will be described.

[0059] Figure 5 It is a block diagram showing the overall configuration of the ultrasonic observation device according to the second embodiment. In addition, in Figure 5 in, right with figure 1 The same components are given the same reference numerals and descriptions thereof are omitted.

[0060] Such as Figure 5 As shown, the ultrasonic observation device 1a is configured to use an ultrasonic probe 2a, a computing unit 4a, and a storage unit 8a instead of figure 1 The ultrasonic probe 2, the computing unit 4, and the storage unit 8 of the ultrasonic observation device 1.

[0061] The ultrasonic probe 2a is constituted relative to figure 1 The ultrasonic probe 2 of the present invention has a signal conversion unit 21 and a sensor unit 22 added. In addition, the calculating part 4a is comprised so that with respect to figure 1 The calculating part 4 of the , has the first position correcting part 12a and the...

no. 3 approach

[0076] Next, a third embodiment will be described.

[0077] The display unit 7 displays various information including the image generated by the image processing unit 5 . The image displayed on the display unit 7 is set as the real-time image under observation, and the image (moving image for TIC analysis) when the correlation value with the reference image is the largest is stored in the device (for example, stored in the moving image storage unit 15) , read out and used when performing TIC analysis. Other structures are the same as those of the first embodiment or the second embodiment.

Abstract

This ultrasonic observation apparatus 1 comprises: an ultrasonic probe 2 that is capable of two-dimensional scanning of an ultrasonic beam by changing the transmit and receive directions of ultrasonic waves to first and second directions; a transmit / receive unit 3 that controls the transmit and receive directions of the ultrasonic beam; an image processing unit 5 that generates volume data of a B-mode image from the results of the scanning of the ultrasonic beam in the first and second directions; an input unit 6 that sets as a reference image an image where a first region of interest is extracted clearly; a storage unit 8 that stores the reference image; and a calculation unit 4 that corrects a scan plane so that an image similar to the reference image set with the input unit 6 is constantly displayed. The calculation unit 4 automatically corrects the position of a second region of interest for analysis of temporal variation of intensity, synchronously with the movement of the first region of interest on the scan plane.

Description

technical field [0001] The present invention relates to an ultrasonic observation device, in particular to an ultrasonic observation device capable of calculating the change of brightness in a region of interest with time. Background technique [0002] An ultrasonic observation device used for examination and diagnosis of a subject that generates an ultrasonic image representing acoustic characteristics inside the subject by transmitting and receiving ultrasonic waves to and from the subject is widely used in the medical field and the like . [0003] An ultrasonic observation device used in the medical field or the like includes an ultrasonic probe capable of transmitting and receiving ultrasonic waves to a subject, and generates a B-mode image that is a cross-sectional image of the subject. A B-mode image is obtained by scanning an ultrasonic beam on a predetermined scanning plane. [0004] For example, Japanese Patent No. 4801229 discloses an ultrasonic observation devic...
