Description

Detailed Description of the Invention (a) Industrial Application Field The present invention transmits ultrasonic waves to a subject, receives the reflected waves, and calculates information inside the subject based on the received signal. The present invention relates to a diagnostic site display method for an ultrasonic diagnostic apparatus that obtains the following.

(B) Prior Art Conventionally, 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-mentioned technical problems, to obtain a tomographic image at the desired diagnosis B13 position with good reproducibility, and to analyze the anatomical relationship between the obtained tomographic f-image and the diagnostic site. The purpose is to make the scientific positional relationship easily readable.

B) Structure In order to achieve the above-mentioned object, the present invention displays an organ pattern for each organ of a subject in a tree-like manner using pixel charcoal coating, and performs ultrasonic detection on the displayed organ pattern. The contact position of the tentacle 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 now be described in detail 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 corresponds to the abdominal organ of the subject.
, for example liver la.

A pattern of the gallbladder 1b, pancreas IC1 kidney 1d, etc. is displayed three-dimensionally by the shading of pixels forming this pattern. Next, on this human body pattern, the contact position of the ultrasonic probe is displayed as a base line 2, and furthermore, the transmission direction of the ultrasonic wave is displayed as a plurality of arrows 4 from the base line 2, respectively. In this way, organ pattern 1 is displayed three-dimensionally, and the diagnosis site,
In other words, since the contact position of the ultrasound probe and the direction of ultrasonic wave transmission are displayed by a base line 2 and an arrow 4 extending from this base line 2, the direction of ultrasonic wave transmission and this direction of wave transmission, which could not be recognized in the past, are displayed. This allows for a more accurate diagnosis because the interrelationship between the body and each organ can be seen at a glance.

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. Organ pattern 1 is selected from organ memory 10 by a control signal from operation unit 12.
The data is read out and sent to the digital scan converter 14, where it is temporarily stored. The data 14 of the organ pattern 1 stored in the digital scan converter 14 is read out as an image display signal at the 'It' V 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. When operated, the baseline position setting signal output from this 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. Furthermore, when the joystick 22 of the operation unit 12 is moved, an angle setting signal is output.
This is provided to arrow generator 24. Since the pattern data of the 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 above-mentioned angle setting signal, processes the coordinates of this, and sends it to the digital scan converter. Send on 14th. When the digital scan converter 14 reads out the organ pattern 1, at the same time,
Since the positional coordinate data of the base line 2 and the positional coordinate data of the arrow 4 whose angle has been set are read out, a display as shown in FIG. 2 appears 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 by the shading of pixels, and an ultrasound probe is placed on each of the displayed organ patterns. The contact position is displayed as a baseline, and the ultrasonic wave transmission direction is displayed as an arrow from the baseline, so the ultrasonic wave transmission direction, which could not be recognized with the conventional technology, can be recognized, and the obtained tomographic It becomes easy to understand the anatomical positional relationship between the 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.
