It is performed based on the magnetic field formed by 9. Magnetic field generator 39
Is installed at an appropriate place such as on the support plate 5, for example.

Since the magnetic field formed by the magnetic field generator 39 has different magnetic field strength and direction at each point in the three-dimensional space, the position sensor 37 detects such a magnetic field, so that the ultrasonic probe 33 Dimensional position and orientation can be detected. The detection signal is input to the imaging unit main body 31 through the cable 35.

Note that the length direction of the ultrasonic beam 303 is the z direction. The θ direction and the φ direction are two directions perpendicular to each other. Such three-dimensional scanning is a pyramid scan.
Also called n). Needless to say, two-dimensional scanning can be performed by fixing the angle in either the θ direction or the φ direction and performing the scanning.

e) and other operating tools.

The operation of this apparatus will be described. FIG. 9 shows a flow chart of the operation of the present apparatus. As shown in the figure, in step 902, preliminary imaging is performed. Preliminary photographing means photographing a three-dimensional image of the portion of the target 7 in the body where the affected portion 9 exists, by the photographing unit 3. The preliminary imaging is performed before the treatment of the affected area 9 is started.

Preliminary imaging is performed by the ultrasonic probe 33, the transmitting / receiving section 36 and the B mode processing section 40. The portion including the ultrasonic probe 33, the transmission / reception unit 36, and the B-mode processing unit 40 is an example of the embodiment of the second imaging means in the present invention.

Next, in step 904, image data and position data are stored. The image data is three-dimensional image data. The position data is data representing the three-dimensional position of the image data. The position data is the position sensor 37.
It is obtained by calculation based on the three-dimensional position and orientation of the ultrasonic probe 33 detected by. These image data and position data are stored in the external memory 146.

Next, in step 906, full-scale photography is performed. The full-scale photographing is to continuously photograph a tomographic image or a three-dimensional image of a portion where the affected part 9 exists from the start to the end of the treatment. This allows real-time (re
an al time) image is obtained. This image is used by the practitioner to observe the condition of the affected area and its surroundings when performing the procedure.

The full-scale photographing is performed by the ultrasonic probe 33, the transmitting / receiving section 36 and the B mode processing section 40. The portion including the ultrasonic probe 33, the transmission / reception unit 36, and the B-mode processing unit 40 is an example of the embodiment of the first imaging means of the present invention.

Next, at step 908, the full-scale photographed image and the preliminary photographed image are simultaneously displayed. Both images are displayed by the display unit 46. As one format of the simultaneous display, for example, as shown in FIG. 10, a real photographed image (a) and a preliminary photographed image (b) are displayed side by side. These images include the affected area image 9 '.

The preliminary photographed image (b) is stored in the external memory 14
It is configured by using the image data of the preliminary photographing stored in 6. Since the three-dimensional position of the cross section during full-scale imaging is known from the three-dimensional position and posture of the ultrasonic probe 33, it is possible to construct a tomographic image of the same cross section by using the three-dimensional image data. Is.

Simultaneous display of the real photographed image and the preliminary photographed image is performed by the image processing unit 44 and the display unit 46. The portion including the image processing unit 44 and the display unit 46 is an example of the embodiment of the display means in the present invention.

Next, in step 910, the applicator 1
Puncture by 3 is performed. Since the full-scale photographing is continuously performed, the applicator image 13 ′ during the puncture can be visually recognized on the image, as shown in FIG. 11,
This allows the practitioner to confirm the entry status of the applicator 13. Since the preliminary photographed image (b) displayed at the same time is photographed in advance, the applicator image 13 'does not appear on it.

After reaching the desired puncture state, in step 912, cauterization of the affected area is performed. That is, the treatment section main body 11 is operated to supply cauterizing power to the applicator 13, and the affected part 9 is cauterized by RF electromagnetic waves or the like radiated from the tip of the applicator 13.

Water vapor is generated in the affected area 9 by cauterization.
Since the water vapor remarkably attenuates the ultrasonic waves, it becomes impossible to photograph the area beyond the deep portion of the affected area image 9'as viewed from the irradiation direction of the ultrasonic waves. Therefore, for example, as shown by hatching in (a) of FIG. 12, a portion beyond the back of the affected part image 9 '(water vapor image) becomes a dark shadow on one surface and the internal structure of the target 7 cannot be seen.

On the other hand, such a phenomenon does not occur in the preliminary photographed image (b) which is displayed at the same time, so that the structure of the portion beyond the back of the affected area image 9'can be clearly seen. Therefore, it is possible to grasp the structure of the portion that cannot be seen in the full-scale shot image (a) by using the preliminary shot image (b) as a reference image. Therefore, there is substantially no inconvenience.

Simultaneous display of the full-scale photographed image and the preliminary photographed image may be performed by superimposing both of them, instead of displaying them side by side as described above. In such a case, even if water vapor is generated in the affected area 9 and a portion behind the water vapor becomes a dark shadow in the full-scale photographed image, a dark shadow is generated in the overlapping portion due to high brightness of the preliminary photographed image. Don't Then, the structure after the affected area 9 is displayed by the preliminary photographed image, and for example, an image as shown in FIG. 13 is obtained, so that there is substantially no inconvenience. Moreover, since the two images are integrated by superimposing them, the observation becomes easy.

The above is an example of cauterizing the affected area 9.
When an ultrasonic contrast agent is spread to the affected area 9, the inconvenience that the structure behind the affected area 9 is hard to see can be solved in the same manner. In that case, as the treatment section 1,
It goes without saying that a device for injecting an ultrasonic contrast agent into a blood vessel is used. Further, an example has been described in which the real-time photographed image and the preliminary photographed image displayed simultaneously are tomographic images, that is, two-dimensional images, but both images are not limited to two-dimensional images and may be three-dimensional images.
