Problems solved by technology

[0004] Meanwhile, there is a problem in the above-mentioned prior art that it is difficult to draw the biopsy needle on the ultrasound image, which will be described below
The problem with the prior art is that in many cases the probe cannot receive the ultrasound beam from the biopsy needle (it is essentially a specular reflection) because the angle of the ultrasound beam relative to the biopsy needle is not taken into account at all; Received, signal is also very weak, therefore, the biopsy needle is difficult to show clearly on the corresponding ultrasound image (eg, the biopsy needle shows intermittently)

no. 1 approach

[0056] In the first embodiment shown below, the outline and features of the ultrasonic diagnostic apparatus of the first embodiment, the configuration of the ultrasonic diagnostic apparatus and its processing flow will be sequentially explained, and finally the advantages obtained by the first embodiment will be explained.

[0057] [Summary and Features (First Embodiment)]

[0058] First, the outline and features of the ultrasonic diagnostic apparatus of the first embodiment will be described by figure 1 to explain. figure 1 is an outline diagram describing the ultrasonic diagnostic apparatus according to the first embodiment. As shown in the same drawing, the ultrasonic diagnostic apparatus brings a probe connected thereto into contact with the body surface to apply ultrasonic waves, receives signals reflected from the body and a biopsy needle inserted into the body, and generates internal and biopsy needle based on the received signals. Ultrasound image (tomogram).

no. 2 approach

[0084] Incidentally, although the first embodiment has explained the effect of the ultrasonic diagnostic apparatus on ultrasonic image processing around the biopsy needle, the present invention is not limited thereto. The radiation direction of the ultrasound signal can be controlled to display the biopsy needle on the ultrasound image.

[0085] Therefore, in the second embodiment described below, the outline and features of the ultrasonic diagnostic apparatus of the second embodiment, the configuration of the ultrasonic diagnostic apparatus and its processing flow will be explained in order, and the advantages of the second embodiment will be explained at the end. Explanation.

[0086] [Summary and Features]

[0087] First, the outline and features of the ultrasonic diagnostic apparatus of the second embodiment will be passed through Figure 5 to explain. Figure 5 is a diagram describing an outline of an ultrasonic diagnostic apparatus according to the second embodiment. ...

Abstract

With the objective of definitely generating a biopsy needle on an ultrasonic image, an ultrasonic diagnostic apparatus according to the present invention brings a probe connected thereto into contact with the surface of a body and applies ultrasound thereto, receives signals reflected from within the body and the biopsy needle inserted in the body, and generates ultrasonic images (tomograms) in the body and at the biopsy needle on the basis of the received signals. Picture elements are added every pixels with respect to range-specified portions of these ultrasonic images to thereby generate an ultrasonic image formed by superimposing the respective pixels. Even while the so-superimposed ultrasonic image is being created, ultrasonic images are sequentially stored. The so-superimposed ultrasonic image and the latest ultrasonic image are displayed on an output unit in combination.

Description

technical field [0001] The present invention relates to an ultrasonic diagnostic device, an ultrasonic image generating method, and an ultrasonic image generating program, wherein ultrasonic waves are applied to a body to be examined through an ultrasonic probe that receives biopsy needles from and inserted into the body reflected ultrasonic waves, and sequentially generate ultrasonic images. Background technique [0002] Hitherto, puncture for the purpose of tissue diagnosis and cytology diagnosis related to a specific part of the body, drainage, implantation of radioactive materials, and the like can be carried out based on images drawn by ultrasonic diagnostic equipment. For example, in Patent Document 1, (Japanese Unexamined Laid-Open Patent No. Sho 61(1986)-31129), when the probe (ultrasonic probe) is in contact with the body surface and the biopsy needle passes through the biopsy needle mounted on the probe When the insertion attachment is inserted into the body, the ...
