[0001]

[Industrial applications]

 The present invention relates to an ultrasonic diagnostic apparatus that records an ultrasonic diagnostic image and its examination site together.

[0002]

[Prior Art]

 FIG. 3 is a diagram showing a display example for performing conventional ultrasonic diagnostic image recording. In recording a diagnostic image performed by an ultrasonic diagnostic apparatus, it is necessary to record a tomographic image of a patient and an examination site thereof. Generally, a device having a function of setting and displaying probe marks indicating the positions of the body pattern and the probe by a graphic pattern as shown in FIG.

[0003]

[Problems to be solved by the device]

 However, in the conventional ultrasonic diagnostic equipment as described above, since the inspection site is recorded simultaneously, it is necessary for the operator to manually select the body pattern and set the position of the probe mark, which is troublesome. There was a problem.

The present invention has been made to solve the above problems, and an ultrasonic diagnostic apparatus does not require an operator to manually set an inspection site when recording an ultrasonic diagnostic image. Aim to get.

[Means for Solving the Problems]

 An ultrasonic diagnostic apparatus with an inspection site imaging function according to the present invention is an ultrasonic diagnostic apparatus for recording both an ultrasonic diagnostic image and an inspection site thereof, and a video camera for capturing a positional relationship between a probe and a patient body. , A video memory that stores one screen of the frozen video image output from the video camera in synchronization with the freeze signal during freeze operation, and an ultrasonic diagnostic image frozen in synchronization with the freeze signal during freeze operation An image synthesizing means for synthesizing together a frozen video image read from the video memory so that it can be displayed, and a recording means for recording the synthetic image output by the image synthesizing means in response to a recording instruction signal. Is.

[0006]

[Action]

 In the present invention, the video camera captures the positional relationship between the probe and the patient body in the ultrasonic diagnostic apparatus that records the ultrasonic diagnostic image and the examination site. The video memory stores one screen of the frozen video image output from the video camera in synchronization with the freeze signal during the freeze operation. The image synthesizing means synthesizes the ultrasonic diagnostic image frozen in synchronization with the freeze signal and the frozen video image read from the video memory so that they can be displayed together during the freeze operation. The recording means records the combined image output from the image combining means in response to the recording instruction signal.

【Example】

 FIG. 1 is a block diagram showing the configuration of an ultrasonic diagnostic apparatus with an inspection site imaging function of the present invention, in which 1 is a probe, 2 is an ultrasonic transceiver, 3 is a tomographic image reconstruction unit, 4 is a freeze key, and 5 is A video camera, 6 is a video memory, 7 is a video switcher, 8 is an image synthesizer, 9 is a display device, 10 is a record key, and 11 is a recording device such as a television printer. FIG. 2 is a diagram for explaining the positional relationship of the apparatus of FIG. 1, in which the examination site where the probe 1 connected to the ultrasonic diagnostic apparatus main body is placed is being photographed by a video camera provided above the patient. Is shown.

The operation of FIG. 1 will be described with reference to FIG. The ultrasonic wave transmitting / receiving unit 2 transmits / receives ultrasonic waves to / from the patient's body via the probe 1, and the received signal obtained as a result is reconstructed into a tomographic image by the tomographic image reconstructing unit 3 and sent to the image synthesizing unit 8. To be done. At the same time, the video camera 5 provided on the upper part of the patient photographs the positional relationship between the patient body and the probe 1, and supplies the video image to the input terminal b of the video switch 7 and the video memory 6.

Since the input terminal b and the output terminal c of the video switching device 7 are turned on during the scanning operation of this apparatus, the video image of the moving image output from the video camera 5 is output via the video switching device 7. The image is supplied to the image synthesizing unit 8, where the tomographic image and the video image of the moving image are synthesized so as to be displayed together on one screen, displayed by the display 9, and supplied to the recording device 11.

As a method for the image synthesizing unit 8 to simultaneously display two images on one screen of the display device 9, for example, two images may be arranged side by side as shown in FIG. 3, or one of them may be displayed. There is a method of displaying the other image by interrupting it in a blank portion or a less important portion of the image, and any method may be used as long as the two images can be displayed together.

Next, when the apparatus is in the freeze operation, a freeze signal generated by pressing the freeze key 4 is supplied to the ultrasonic wave transmitting / receiving section 2, the tomographic image reconstruction section 3, the video memory 6 and the video switcher 7, respectively. Then, the video switch 7 operates so that the input terminal a and the output terminal c are turned on. The video memory 6 temporarily stores one screen of video image obtained by freezing the video image supplied from the video camera 5 in synchronization with the freeze signal (temporary freeze signal of image), and the frozen video can be stored. The image is read out and supplied to the image synthesizing unit 8 via the video switcher 7. At the same time, the freeze signal supplied to the ultrasonic wave transmitting / receiving unit 2 and the tomographic image reproducing unit 3 also freezes (temporarily freezes) the tomographic image output from the tomographic image reproducing unit 3 in synchronization with the freeze signal.

The image synthesizing unit 8 synthesizes the frozen (temporarily frozen) tomographic image and the video image in synchronization with the freeze signal so that they can be displayed together, and displays them on the display 9 and also the storage device. 11 is supplied. Since the same image signal as the image displayed on the display 9 is constantly input to the storage device 11, the composite image at the moment when the operator presses the record key is recorded. That is, instead of the body pattern and probe mark indicating the conventional inspection site, a frozen video image captured by a video camera is automatically recorded together with an ultrasonic diagnostic image.

[0013]

[Effect of the device]

 As described above, according to the present invention, in an ultrasonic diagnostic apparatus that records an ultrasonic diagnostic image and its examination site together, a video camera captures the positional relationship between the probe and the patient's body, and freezes during freeze operation. A single screen of video image frozen from the video image output from the video camera in synchronization with the signal and an ultrasonic diagnostic image frozen in synchronization with the freeze signal are combined and automatically recorded together. Therefore, it is not necessary to select the body pattern and set the position of the probe mark as in the conventional case, and the workability of the operator can be improved.
