Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a diagnostic apparatus such as an ultrasonic diagnostic apparatus that displays diagnostic images on a monitor.

(b) Prior art and its problems In recent years, ultrasound diagnostic techniques have been established, and a photo book of diagnostic examples based on this diagnostic technique, the so-called ultrasound diagnostic atlas, has been published. Basic diagnostic examples for sonic diagnosis are included for each diagnosis target (for each organ). A doctor looks at this ultrasonic diagnostic atlas and performs a diagnosis according to the above-mentioned diagnostic technique.

However, when making a diagnosis using an ultrasound diagnostic atlas, it is necessary to compare the diagnostic images on the monitor of the ultrasound diagnostic device with the diagnostic examples on the ultrasound diagnostic atlas. You have to take your eyes off the screen and look at the ultrasound diagnostic atlas, which makes diagnosis difficult and can also make you feel uneasy. moreover,
It is inconvenient to always carry an ultrasound diagnostic atlas, which is a photo collection of diagnostic examples.

The present invention has been made in view of the above points, and allows comparison of diagnostic images and diagnostic examples without taking your eyes off the monitor, and eliminates the need for diagnostic example collections such as ultrasound diagnostic atlases. The purpose is to provide a diagnostic device that

(C) Means for Solving the Problems In the present invention, in order to achieve the above-mentioned object, echo signal data etc. obtained by transmitting and receiving ultrasonic waves are written in an image memory, and data read out from this image memory. In a diagnostic device that displays diagnostic images on a monitor based on
a diagnostic example memory in which signal data corresponding to a plurality of basic diagnostic examples are stored; a selection means operated to select a desired diagnosis example from the plurality of diagnostic examples; reading means for reading out signal data corresponding to a desired diagnostic example from the diagnostic example memory based on the output, the signal data corresponding to the desired diagnostic example read from the diagnostic example memory and the signal data corresponding to the desired diagnostic example read from the image memory; Based on the read data, a diagnostic example and a diagnostic image are simultaneously displayed on the monitor.

(D) Effect According to the above configuration, the desired diagnostic example and the diagnostic image read from the diagnostic example memory are displayed together on the monitor.

(e) Examples Examples of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

In the figure, ■ is an ultrasonic diagnostic device, 2 is an ultrasound probe that transmits ultrasonic waves to the subject and receives the reflected waves, 3 is a transmitting circuit that outputs a transmitted signal, and 4 5 is a wave receiving circuit that amplifies and detects the echo signal from the ultrasonic probe 2;
is an A/D that converts the echo signal from the receiving circuit 4 into A/D.
a conversion circuit; 6 is an image memory into which echo signal data from the A/D conversion circuit 5 or signal data from a diagnosis example memory 9 (to be described later) is written or read; 8 is a monitor.

The ultrasonic diagnostic apparatus 1 of this embodiment includes a diagnostic example memory 9 in which signal data corresponding to a plurality of basic diagnostic examples during ultrasonic diagnosis are stored.

The diagnosis example memory 9 stores information at predetermined addresses for each diagnosis target, for example, for each organ such as the liver, kidney, and gallbladder. That is, this diagnostic example memory 9 stores basic diagnostic examples as in the conventional ultrasonic diagnostic atlas.

Reference numeral 10 denotes a keyboard as a selection means operated to select a desired diagnosis example from among the plurality of diagnosis examples in the diagnosis example memory 9, and is provided with operation keys corresponding to each diagnosis example. Reference numeral 13 denotes a write address generation circuit that generates a write address to the image memory 6, and the output of this write address generation circuit 13 is given to the image memory 6 as well as a readout control circuit 11 as a readout means.
is given to.

The readout control circuit 11 generates a corresponding readout address based on the output of the keyboard 10 corresponding to a desired diagnosis example and supplies it to the diagnosis example memory 9. Diagnostic example memory 9 according to the read address from read control circuit 11
The signal data corresponding to the desired diagnostic example read out from the switch circuit I2 is input to the switching circuit I2.

The switching circuit 12 is controlled by a switching signal from the readout control circuit 11, and switches to the diagnostic example memory 9 side during the period when this switching signal is applied, and during other periods, the A/D Switched to the conversion circuit 5 side.

In this embodiment, the signal data of the desired diagnostic example read from the diagnostic example memory 9 is written into a predetermined writing area of the image memory 6. Address generation circuit 1
Based on the write address from No. 3, a switching signal is outputted over a period corresponding to the predetermined write area, and a read address is generated. Therefore 1.
A write address generation circuit 13 is provided in the second write area.
The signal data of the diagnostic example from the diagnostic example memory 9 is written in synchronization with the write address from the image memory 6, and the echo signal data from the A/D conversion circuit 5 is written to an area other than the writing area of the image memory 6. .

As a result, in the image memory 6, the signal data of the diagnosis example is written in a predetermined writing area, and the echo signal data of the organ currently being diagnosed is written in other areas.

The signal data in the image memory 6 is read out in synchronization with the TV scanning speed and displayed on the monitor 8. In this embodiment, as shown in FIG. 2, the rectangular first . A diagnostic image and a diagnostic example are displayed simultaneously in each of the second display areas A and B.

Note that when the keyboard 10 is not operated or when the clear key on the keyboard 10 is operated, the readout control circuit 11 does not generate a switching signal and a readout address, and in this case, the A/D conversion signal is stored in the image memory 6. Only the echo signal data from the circuit 5 is written, therefore, no diagnostic example is displayed, and only the diagnostic image is displayed on the monitor 8 as in the conventional example.

In this way, the diagnostic image currently being diagnosed and the diagnostic example are displayed on the monitor 8 at the same time as necessary, making it possible to perform a diagnosis according to the diagnostic technique without the need for an ultrasound diagnostic atlas as in the conventional case. It becomes possible.

Therefore, it is possible to eliminate the problem of causing the patient to feel anxious and having to carry an ultrasound diagnostic atlas with him or her at all times, as in the conventional case.

In the above embodiment, the signal data in the diagnostic example memory 9 is written into a predetermined write area of the image memory 6, and the signal data in the image memory 6 is read out to display the diagnostic image and the diagnostic example on the monitor 8. However, in another embodiment of the invention, without writing the signal data of the diagnostic example memory 9 to the image memory, the echo signal data from the image memory 6 and the signal from the diagnostic example memory 9 can be combined as shown in FIG. The configuration may be such that the diagnostic image and the diagnostic example are displayed in a predetermined display area of the monitor 8 by switching between the diagnostic image and the data using the switching circuit 13.

Although the above embodiment describes an ultrasonic diagnostic apparatus, the present invention is not limited to an ultrasonic diagnostic apparatus.
Of course, the present invention can also be applied to other diagnostic devices that compare diagnostic images and diagnostic examples.

(F) Effects As described above, according to the present invention, a desired diagnostic example is read out from the diagnostic example memory in which a plurality of basic diagnostic examples are stored and displayed on the monitor together with the diagnostic image. Diagnosis can be performed without requiring a collection of diagnostic examples such as an ultrasound diagnostic atlas as in the conventional case.
