Problems solved by technology

[0008] However, in the past, images of tissues sampled by needle biopsy were not retained as evidence, so confirmation could not be performed, and needle biopsy had to be performed wastefully again

no. 1 approach

[0039] figure 1 It is a block diagram which shows the structure of the ultrasonic diagnostic apparatus 1 which concerns on one Embodiment of this invention.

[0040] The ultrasonic diagnostic apparatus 1 includes an apparatus main body 1A, a probe 2 as an ultrasonic contactor, an input device 3, and a monitor 4 as a display device.

[0041] In the apparatus main body 1A, an ultrasonic transmitting unit 11, an ultrasonic receiving unit 12, a B-mode processing unit 13, a Doppler processing unit 14, an image generating unit 15 as an image generating device, an image memory 16, an image synthesizing unit 17, A control processor (CPU) 18, an internal storage unit 19, an interface unit 20, and an optical sensor (not shown) are controlled.

[0042] The probe 2 described above generates ultrasonic waves according to a drive signal from the ultrasonic wave transmitting unit 11 and transmits them to the subject P. As shown in FIG. The probe 2 includes a plurality of piezoelectric vibr...

[0073] Figures 9 to 13 A second embodiment of the present invention is shown.

[0074] In addition, about the same part as the part demonstrated in the said 1st Embodiment, the same code|symbol is attached|subjected and the detailed description is abbreviate|omitted.

[0075] In the above-described first embodiment, the needle biopsy is performed by bringing the distal end portion of the probe 2 into contact with the surface of the subject P to scan ultrasonic waves three-dimensionally, but in the second embodiment, as Figure 9 As shown, the needle biopsy is performed by bringing the distal end portion 2a of the probe 2 into contact with the surface of the subject P to scan ultrasonic waves two-dimensionally.

[0076] Next, the case where a needle biopsy is performed by scanning ultrasonic waves two-dimensionally will be described.

[0077] First, the puncture needle 22 is mounted in the puncture adapter 21 of the probe 2 . Next, the distal end portion 2a of the probe 2 i...

Abstract

An ultrasonic diagnostic apparatus includes an image creating unit (15) configured to create an image (26a) of an affected area (26) and an image (22a) of a puncture needle (22) inserted into a subject (P) by means of an ultrasonic scanning operation, and a monitor (4) configured to display the image (26a) of the affected area (26) and the image (22a) of the puncture needle (22) created by the image creating unit (15), wherein the image creating unit (15) displays a tissue expected to be extracted from the affected area (26) as an image on the monitor (4) before the puncture needle (22) is inserted into the affected area (26).

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on and claims priority from Japanese Priority Application No. 2008-032253 filed on February 13, 2008, the entire contents of which are incorporated herein by reference technical field [0003] The present invention relates to an ultrasonic diagnostic apparatus that supports the sampling operation of a puncture needle for sampling tissue in a sampled part. Background technique [0004] In recent medical care, when, for example, cancer is suspected through image diagnosis, needle biopsy is often performed for final determination. Among puncture needles for needle biopsy, there are puncture needles having a dual structure including an outer needle and an inner needle inserted into the outer needle. In the case of performing a needle biopsy using this dual-structure puncture needle, the injection button is pressed until the puncture needle is inserted into the vicinity of the lesion to be sampled ...
