DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic diagnostic apparatus.

[0002]

2. Description of the Related Art For example, a B-mode image as a tomographic image of a heart or a Doppler image as a blood flow image can be displayed on a CRT screen of an ultrasonic diagnostic apparatus, and a B-mode image is displayed. There are some that can automatically measure the cross-sectional area of the heart by operating the cursor, or can automatically measure the blood flow velocity of the heart in the required direction by displaying a Doppler image and specifying it with a marker .

In such an ultrasonic diagnostic apparatus, in order to measure the blood flow from each measurement data of the cross-sectional area of the heart and the blood flow velocity obtained by the automatic measurement, each of them is stored in the memory of the ultrasonic diagnostic apparatus. The measurement data is read out and redisplayed on the CRT screen, and for example, the blood flow is automatically measured from the redisplayed measurement data. Until now, each ultrasonic image corresponding to the measurement data is simultaneously measured. Was not displayed.

[0004]

As described above, since the measurement data is not displayed simultaneously with the corresponding ultrasonic image, the measurement of the heart blood flow rate and the measurement data of the heart cross-sectional area and the blood flow velocity Whether the measurement data is correct for the same patient,
Whether the same patient has the same measurement date and time, or whether the cross-sectional area measurement data is from the heart or other affected tissues, can be checked directly on the screen. And there is a possibility that a measurement error may occur.

Therefore, according to the present invention, when a plurality of measurement data are redisplayed on a screen, an image corresponding to the data can be displayed on the screen, and an ultrasonic wave capable of performing required measurement correctly can be obtained. It is intended to provide a diagnostic device.

[0006]

In order to achieve the above object, an ultrasonic diagnostic apparatus according to the present invention has an additional memory, measurement data designating means, and a control circuit.
In the additional memory, various image data for displaying an ultrasonic image on a screen and measurement data when measurement is performed based on these ultrasonic images are written in association with each other. Designates reading of arbitrary measurement data from the additional memory,
The control circuit, when the reading of a plurality of measurement data from the additional memory is specified by the measurement data specifying means, reads the image data corresponding to the measurement data together with the specified plurality of measurement data, and displays the image data on the screen. It is characterized by performing control for displaying a plurality of measurement data and a plurality of images corresponding thereto.

[0007]

When obtaining measurement data for another ultrasonic diagnosis from a plurality of measurement data written in the additional memory, an ultrasonic image corresponding to each of the plurality of measurement data is displayed on a screen. Thus, measurement for the other ultrasonic diagnosis can be performed correctly.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram of a main part of an ultrasonic diagnostic apparatus according to an embodiment of the present invention, and FIG. 2 is a diagram showing a display screen of an image display. In FIG. 1, 1 is an ultrasonic probe,
Reference numeral 2 denotes a transmission / reception circuit, 3 denotes an image display, 4 denotes a control circuit, 5 denotes an operation device as measurement data designating means, and 6 denotes an additional memory.

In the present embodiment, image data for displaying an ultrasonic image on the screen of the image display 3 in the additional memory 6 and the measurement data when measurement is performed based on the ultrasonic image. When the reading of the plurality of measurement data from the additional memory 6 is designated by the control circuit 4, each image data corresponding to the designation is read together with the plurality of measurement data, and the measurement data and the It is characterized in that control for redisplaying the corresponding image data on the image display 3 is performed.

In operation, the ultrasonic probe 1 is excited by a drive pulse from the transmission / reception circuit 2, so that ultrasonic waves are emitted from the ultrasonic probe 1 to an affected part of the subject, for example, the heart. The reflected ultrasonic wave returned from the heart is received by the ultrasonic probe 1, amplified and detected by the transmission / reception circuit 2, and displayed on the screen 7 of the image display 3 by display control of the control circuit 4. Is displayed as an ultrasonic image.

In this display, the control circuit 4 includes an operating device 5
2A, the tomographic image 8 of the heart is displayed and controlled as a B-mode image as shown in FIG. 2A, and the blood flow image 9 of the heart is converted into a D-mode image as shown in FIG. Display control.

Further, when the control circuit 4 measures the cross-sectional area of the tomographic image 8 of the heart by operating the cursor, the measurement data 10 is displayed on the display screen as shown in FIG. The additional memory 6 stores the measurement data 10
And the image data of the tomographic image 8 of the heart are written (stored) in association with each other and stored, and a blood flow direction is designated by a marker from the blood flow image 9 of the heart, and the designated blood flow is designated. When the blood flow velocity in the direction is measured, the measured data 11 is displayed on the display screen as shown in FIG. 2B, and the measured data of the blood flow velocity together with the measured data 11 is stored in the additional memory 6. Write and store them in association with each other.

Next, when the measurement of the blood flow rate of the heart is designated by the operating device 5, the control circuit 4 measures the image data of the tomographic image of the heart and the cross-sectional area corresponding to the tomographic image from the additional memory 6. The data is read, and the image data of the blood flow image of the heart and the measurement data of the blood flow velocity corresponding thereto are read out, and the tomographic image of the heart corresponding to both the measured data of the cross-sectional area and the blood flow velocity The image data of the blood flow image and the blood flow image are controlled to be displayed again on the image display 3 as shown in FIG.

Therefore, the measurement data of the cross-sectional area and the blood flow velocity when measuring the blood flow of the heart from the display of FIG. 2 (c) correctly correspond to the blood flow measurement site of the heart. Confirmation becomes easy.

As apparent from the above description, according to the present invention, when obtaining measurement data for another ultrasonic diagnosis from a plurality of measurement data written in the additional memory, the plurality of measurement data Since the corresponding ultrasonic images are displayed on the screen, the measurement for the other ultrasonic diagnosis can be performed correctly. In particular, a plurality of image data such as image data of a B-mode cross-sectional image and a blood flow image of the heart, and the image data such as a cross-sectional area data corresponding to the B-mode cross-sectional image and a blood flow velocity data corresponding to the blood flow image. Can be displayed in one screen in association with each other, and the image and the measurement data can be reliably associated with each other, and the diagnostic accuracy can be improved.
