Description

[Detailed description of the invention] (a) Industrial application field The present invention transmits ultrasonic waves to a subject, receives the reflected waves, and obtains information inside the subject based on the received signal. The present invention relates to a diagnostic site display method for an ultrasonic diagnostic apparatus.

(B) Prior Art Conventional A subject to be examined in ultrasonic diagnosis, for example, a diagnostic region of a human body, is displayed two-dimensionally (two-dimensionally) along with the human body, as shown by diagonal lines in FIG. In this method of displaying the diagnosis area in a two-dimensional manner, although the contact position of the ultrasound probe can be determined, it is not possible to recognize the direction in which the ultrasound waves are transmitted from the contact position, and this results in poor reproducibility. This was a problem in making accurate diagnosis.

(c) Purpose The purpose of the present invention is to solve the above technical problem,
It is an object of the present invention to make it possible to obtain a tomographic image at a desired diagnostic site with good reproducibility, and to make it possible to easily read the anatomical positional relationship between the obtained tomographic image and the diagnostic site.

(D) Configuration In order to achieve the above-mentioned object, the present invention displays an organ pattern for each organ of a subject three-dimensionally using pixel shading, and then transmits ultrasonic waves onto the displayed organ pattern. The contact position of the probe is indicated by a baseline, and the direction of ultrasonic wave transmission is indicated by an arrow from the baseline.

(e) Examples Examples of the present invention will be described in detail below with reference to the drawings. FIG. 2 is a diagram showing a display on a monitor when the display method of one embodiment of the present invention is applied to human organs. In this example, organ pattern 1 corresponding to the abdominal organ of the subject, for example, liver 1
A, gallbladder 1b, pancreas 1c, kidney 1d, and other patterns are displayed three-dimensionally by the shading of the pixels that make up the pattern. Next, the contact position of the ultrasound probe is displayed on this human body pattern as baseline 2,
Furthermore, the transmission direction of the ultrasonic waves is indicated by a plurality of arrows 4 from the base line 2, respectively. In this way, the organ pattern 1 is displayed three-dimensionally, and the diagnosis site, that is, the contact position of the ultrasound probe and the ultrasound transmission direction are indicated by the base line 2 and the arrow 4 extending from the base line 2.
Since the ultrasonic wave transmission direction, which was previously unrecognizable, and the mutual relationship between this wave transmission direction and each organ can be seen at a glance, this enables more accurate diagnosis.

FIG. 3 is a block diagram of an ultrasonic diagnostic apparatus according to this diagnosis site display method. Data of organ pattern 1 is written in the organ memory 10 in advance. Data of organ pattern 1 is read out from organ memory 10 in response to a control signal from operation unit 12, and is sent to digital scan converter 14, where it is temporarily stored. The data of the organ pattern 1 stored in the digital scan converter 14 is read out as an image display signal at the TV scanning speed and output to the monitor 16. Furthermore, in order to set the contact position of the ultrasound probe on the subject, it is necessary to determine the base line 2 position on the organ pattern 1.
To do this, when a switch 18 on the keyboard of the operating section 12 is operated, a base line position setting signal outputted from the switch 18 is applied to the line segment generator 20. The line segment generator 20 calculates the position coordinates of the base line 2 based on this base line position setting signal, and sends this data to the digital scan converter 14.
Further, when the joystick 22 of the operating section 12 is moved, an angle setting signal is output, and this signal is applied to the arrow generator 24. Since the pattern data of arrow 4 is stored in advance in the arrow generator 24,
The arrow generator 24 sets the direction of the arrow 4 based on the angle setting signal, processes the coordinates, and sends it to the digital scan converter 14. The digital scan converter 14 converts the organ pattern 1 into
When reading out, the position coordinate data of the base line 2 and the position coordinate data of the arrow 4 with the angle set are read out at the same time, so a display as shown in FIG. 2 will appear on the screen of the monitor 16. .

(f) Effects As described above, according to the present invention, an organ pattern corresponding to each organ of a subject is displayed three-dimensionally using pixel shading, and on each of the displayed organs,
The contact position of the ultrasonic probe is displayed as a baseline, and the ultrasonic wave transmission direction is displayed as an arrow from the baseline, so it is possible to recognize ultrasonic wave transmission directions that could not be recognized with conventional technology. Therefore, it becomes easy to understand the anatomical positional relationship between the obtained tomographic image and the diagnostic site. Therefore, reproducibility at the desired diagnostic site is improved, the same tomographic image can be obtained even if the diagnosing doctor and the device operator are not necessarily the same person, and division of work can also be realized. This is an excellent practical effect.
