[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic diagnostic apparatus having a multi-memory function capable of obtaining an ultrasonic image of a diagnostic region inside a subject using ultrasonic waves and storing a plurality of image data. In particular, it relates to an ultrasonic diagnostic apparatus capable of arbitrarily editing a plurality of image data stored by the multi-memory function for display.

2. Description of the Related Art A conventional ultrasonic diagnostic apparatus of this type is shown in FIG.
As shown in FIG. 1, a probe 1 that transmits and receives ultrasonic waves in the subject.
And a reflection echo detection unit 2 that controls the probe 1 to transmit an ultrasonic wave and detect a reflection echo signal from a received reflection signal, and a reflection echo signal from the reflection echo detection unit 2 A / D converter 3 to be converted and a memory section 4 for storing image data from the A / D converter 3
A multi-memory section 5 for storing a plurality of image data sequentially output from the A / D converter 3, and a multi-memory control section 6 for controlling writing and reading of image data to and from the multi-memory section 5. A display circuit section 7 for converting the image data read from the memory section 4 into a video signal, an image display section 8 for inputting the video signal from the display circuit section 7 and displaying it as an image, and the image display section 8 And an image recording device 9 for photographing and recording the image displayed on the screen. In FIG. 2, reference numeral 10 indicates a central processing unit (CPU) that controls the operation of each of the above components,
Reference numeral 11 indicates an operation panel for inputting an operation command to the CPU 10.

Then, the operation of the probe 1 and the reflection echo detector 2 collects the reflection echo signal from the diagnostic region in the subject, and the image which seems to be effective for diagnosis is obtained through the A / D converter 3. The image data is stored in the multi-memory unit 5 for a plurality of sheets, and the data of the stored images are sequentially read out later and displayed on the image display unit 8.
Alternatively, the screen of the image display unit 8 is divided into, for example, four or one.
Four images or 16 images, which are divided into six and reduced on one screen, are multi-displayed, and a necessary image is selected from them, and then displayed on one screen in a large size for detailed observation. Further, among the images displayed on the image display unit 8, necessary images are photographed by the image recording device 9 and stored in a hard copy state.

[0004]

However, in such a conventional ultrasonic diagnostic apparatus, in order to search for a necessary image from the images stored in the multi-memory unit 5, the multi-memory is used each time. Since a plurality of images stored in the unit 5 are sequentially displayed and the necessity or unnecessaryness is determined while observing those images, it is time-consuming to find a desired image. Alternatively, the image display unit 8
Even if you divide the screen into multiple screens to display reduced images in multiple display and select and display the required images from these, when you are trying to find the desired image from the other image groups, switch to the multiple display once. I had to go back and select from them, and then enlarge and display it, which was also time-consuming. Therefore, the efficiency of image diagnosis may decrease.

Further, when a color video printer is used as the image recording device 9, for example, it takes about 1 minute to make a hard copy of one image, and after waiting this time, the next necessary image is formed. It is necessary to select, photograph and record this image, and further select a necessary image, which makes the operation very complicated and takes a long time. Therefore, the utilization efficiency of the device is lowered.

Therefore, the present invention addresses such problems and provides an ultrasonic diagnostic apparatus capable of arbitrarily editing a plurality of image data stored by a multi-memory function for display. To aim.
