Problems solved by technology

[0005] Among them, the image quality of living tissue drawn in an ultrasonic image generated by oblique scanning is degraded due to the influence of side lobes, etc., compared with that of a non-oblique scan.
Therefore, even if the visibility of the puncture needle in the synthesized image is somewhat improved, the observation of the nature of the tissue lesion is not optimal, and thus the diagnostic ability using the synthesized image is reduced.
That is, since the ultrasonic beam is irradiated perpendicularly to the puncture needle, it is easy to see the puncture needle, and on the other hand, due to problems such as the beam shape, grating side lobes and the like occur, thereby deteriorating the information of living tissue.

no. 1 Embodiment approach

[0024] 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 configuration of the ultrasonic diagnostic apparatus according to the first embodiment. Such as figure 1 As shown, the ultrasonic diagnostic apparatus according to the first embodiment includes an ultrasonic probe 1 , a monitor 2 , an input device 3 , and an apparatus main body 10 .

[0025] The ultrasonic probe 1 is detachably connected to the device main body 10 . The ultrasonic probe 1 has a plurality of piezoelectric vibrators, and these piezoelectric vibrators generate ultrasonic waves in accordance with drive signals supplied from a transmission / reception unit 11 included in an apparatus main body 10 described later. In addition, the ultrasonic probe 1 receives reflected waves from the subject P and converts them into electrical signals. In addition, the ultrasonic probe 1 has a matching layer provided ...

no. 2 Embodiment approach

[0083] In the second embodiment, for the case where the selection process of the third ultrasonic image is executed after brightness adjustment is performed on the second ultrasonic image group, the Figure 7 etc. for explanation. Figure 7 It is a figure for demonstrating the structure of the control part concerning 2nd Embodiment.

[0084] Such as Figure 7 As shown, the control unit 18 according to the second embodiment and figure 1 Compared with the control unit 18 according to the illustrated first embodiment, it is different in that it further includes an adjustment unit 18e. The following description will focus on this. In addition, similarly to the first embodiment, also in the second embodiment, the first ultrasonic image and the second ultrasonic image group are generated after the first scan and the second scan are performed.

[0085] Here, if the ultrasonic beam is tilted, the brightness of the entire image will increase due to the influence of side lobes, or t...

no. 3 Embodiment approach

[0098] In the third embodiment, a case will be described in which the selection process of the third ultrasonic image is executed after the image processing using the first ultrasonic image is performed on the second ultrasonic image group.

[0099] The control unit 18 and use of the third embodiment figure 1 The control unit 18 according to the first embodiment described above has the same configuration. However, in the third embodiment, the processing of the selection unit 18b included in the image control unit 181 is different from the first and second embodiments. The following description will focus on this. Also in the third embodiment, as in the first and second embodiments, after the first scan and the second scan are performed, the first ultrasonic image and the second ultrasonic image group are generated.

[0100] The image generation control unit 181 according to the third embodiment controls the image generation unit 14 to generate a high-brightness drawing based...

Abstract

Embodiments relate to ultrasound diagnosis apparatus and a controlling method, which can improve recognizability of both tissues of living organisms and punture needles . The ultrasound diagnosis apparatus includes: a scan controlling unit that exercises control to perform a first scanning process by transmitting an ultrasound wave in a first direction and a second scanning process by transmitting an ultrasound wave in each of a plurality of directions; an image generating unit that generates a first ultrasound image and second ultrasound images from the first and the second scanning processes, respectively; an image generation controlling unit that has a needle image generated, based on an analysis result on the brightness distribution of each member of a group of images based on the first ultrasound image and the second ultrasound images or an analysis result on the brightness distribution of each of the second ultrasound images; an image synthesizing unit that generates a synthesized image from the first ultrasound image and the needle image; and a display controlling unit that displays the synthesized image.

Description

[0001] This application claims the priority of Japanese Patent Application No. 2011-081986 filed on April 1, 2011 and Japanese Patent Application No. 2012-41505 filed on February 28, 2012, and all of the aforementioned Japanese Patent Applications are cited in this application content. technical field [0002] Embodiments relate to an ultrasonic diagnostic apparatus and a control method. Background technique [0003] Conventionally, ultrasonic diagnostic equipment has been frequently used in biological tissue examinations and radio frequency therapy (RFA: Radio Frequency Ablation), etc. The case of a puncture. However, depending on the position of the lesion or the insertion angle of the puncture needle, it may be difficult to see the puncture needle. In this case, the puncture is performed while observing the movement of the tissue when the puncture needle is moved. [0004] Therefore, in recent years, in order to improve the visibility of the puncture needle during punct...
