Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ultrasonic diagnostic apparatus using a biplane probe, and more particularly to an ultrasonic diagnostic apparatus capable of setting a body pattern of two cross sections by one operation.

[0002]

[Prior art]

 An ultrasonic diagnostic apparatus emits ultrasonic waves from a probe into a subject, receives signals reflected from tissues and lesions in the subject with the probe, and a tomographic image formed by the reflected signal is displayed on a CRT. It is a device that is displayed on and used for diagnosis.

A biplane probe is a probe used in this ultrasonic diagnostic apparatus. An example of this biplane probe is shown in FIG. In the figure, 1 is a biplane probe having two orthogonal ultrasonic irradiation surfaces. Reference numeral 2 denotes a cross-section element for imaging a cross-section image, and its ultrasonic wave irradiation pattern is an orthogonal pattern 3 orthogonal to the biplane probe 1. Reference numeral 4 is an element for longitudinal section for imaging a longitudinal section image, and its irradiation pattern is a parallel pattern 5 parallel to the biplane probe 1. As shown in the figure, the cross section obtained by the biplane probe 1 can obtain two tomographic images, a cross section parallel to the axial direction of the biplane probe 1 and a cross section perpendicular to the axis.

The biplane probe 1, for example, in the case of transrectal tomographic image acquisition, can obtain two tomographic images by irradiation of ultrasonic waves once, and thus data can be obtained in a short time. , Can increase patient throughput. Furthermore, it is very effective to be able to image at one time under the condition that the position of the place of shooting is not changed.

[0005]

[Problems to be solved by the device]

 By the way, in the case of photographing a part where the imaged part is difficult to capture, when this image is taken as a picture, the imaged part of the tomographic image is difficult to see, so a contour image of the imaged part is displayed on a part of the CRT screen. The method of clarifying the photographed part on the photograph from the contour image is taken. This contour image is called a body pattern.

When it is desired to display a body pattern when simultaneously scanning two orthogonal cross sections with a biplane probe, conventionally, after displaying a body pattern on one surface, a body pattern on another surface is displayed by a new operation. However, the adjustment is time-consuming and patient throughput is poor.

The present invention has been made in view of the above points, and an object thereof is to enable the setting of body patterns of two surfaces to be set in one operation in transmission and reception using a biplane probe. It is to realize a sound wave diagnostic apparatus.

[0008]

[Means for Solving the Problems]

 The present invention, which solves the above-mentioned problems, is an ultrasonic diagnostic apparatus that performs transmission and reception using a biplane probe, and obtains two elements that are obtained by two orthogonally arranged elements and that are displayed on the same screen. A graphic storage means for storing the necessary number of sets of body patterns for one image, each set of two body patterns corresponding to each image, and two sets suitable for the two images are set as one set. An input device for selectively inputting a body pattern and a memory for temporarily storing a set of body patterns read out from the graphic storage means and displaying the set on a CRT are provided, which correspond to two orthogonal images. The feature is that two body patterns are input by one operation.

[0009]

[Action]

 The two orthogonal elements of the biplane probe provide the reflected wave signal of the orthogonal plane. When a body pattern is selected by the input device according to the pointing direction of the biplane probe, other orthogonal body patterns are also read from the graphic storage device at the same time, stored in the memory once, and obtained from the biplane probe on the CRT. The displayed image is superimposed and displayed. That is, two body patterns for two images can be obtained by one operation.

Reference numeral 13 is a B-mode processing circuit that detects and amplifies the output signal of the receiving beamformer 12 to obtain a B-mode signal. The output signal is displayed on the CRT 15 as a signal for television display by the DSC 14.

Reference numeral 16 is a graphic storage device in which a plurality of types of body pattern pairs are stored. The stored body pattern will be described with reference to the example shown in FIG. In the figure, reference numeral 21 is a longitudinal sectional image obtained by scanning the element 4 for longitudinal section of the biplane probe 1, and 22 is a transverse sectional image similarly obtained by scanning element 2 for transverse section of the biplane probe 1.
