Abstract

PURPOSE:To perform random-accessible reproduction of the picture of a desired patient at a high speed without spending a useless time by recording an address signal, responding to patient information during recording of a picture, on a video tape and retrieving the address signal during reproduction of a picture. CONSTITUTION:When an ultrasonic projected picture of each patient is recorded on the video tape of a VTR 2, address signals ADD1.ADD2,... corresponding to patient information are recorded on a control rack 9c of a video tape 9 by an interface circuit 6 in a way to input each patient information through previous key operation of a control panel 3. When the picture of a desired patient is displayed through reproduction of the tape, through key operation of the control panel 3, information of the desired patient is inputted, and an address signal corresponding to picture patient information, e.g. ADD2 corresponding to, for example, a patient (b), is retrieved through control of a CPU 4. The retrieve is effected at a high speed equal to that of a normal rapid feed and rewinding, and random-accessible reproduction of the patient (b) is effected at a moment when retrieve is carried out. Thus, only by inputting necessary patient information random-accessible reproduction of the picture of the patient can be performed at a high speed.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to ultrasonic diagnostics in which images captured by ultrasound are recorded on a videotape recorder, and any image is retrieved and played back as necessary. Regarding equipment.

(Prior art) In an ultrasound diagnostic device, ultrasound images are taken for each patient in B mode, 9M mode, and 87M mode.

Images in each image mode, such as a D-mode image, are recorded on video tape. Then, the desired patient's image is displayed by playing the videotape as needed, and the diagnostic image is reexamined and remeasured.

In order to play back a desired image, the value of the tape counter of the videotape device must be recorded in advance at the time of recording so that the position on the videotape at which this image is recorded can be known. ing. As a result, by fast-forwarding or rewinding the tape to the tape counter value corresponding to recording, cue playback can be performed from this portion.

(Problems to be Solved by the Invention) However, in the conventional ultrasonic diagnostic apparatus, there is a problem in that the value of the tape counter must be recorded one by one during recording, which is cumbersome. In addition, if you fail to record or lose the recording paper, you will have to frequently fast-forward or rewind to retrieve the desired patient's image, and you will have to search for that image. You will end up wasting your time.

The present invention has been made in response to the above-mentioned problems.
It is an object of the present invention to provide an ultrasonic diagnostic apparatus that can quickly locate and reproduce images of a desired patient without wasting time.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an ultrasonic technology that records ultrasound-captured images on a videotape recorder and extracts and plays back arbitrary images as needed. The ultrasound diagnostic apparatus is characterized by comprising means for recording an address signal corresponding to patient information on a videotape when recording an image, and means for searching for the address signal and cueing from this part when reproducing the image. It is something to do.

(Function) An address signal corresponding to patient information is recorded in advance on the videotape during image recording, and by searching for this address signal during playback, it is possible to quickly cue and play back images of a desired patient. can.

In addition, if necessary, an index signal corresponding to the image mode of each patient is recorded, and by searching this index signal together with the address signal, the image of the desired patient in the desired mode can be quickly retrieved and played back. It becomes possible to do so. Therefore, no time is wasted in reproducing images of a desired patient.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the ultrasonic diagnostic apparatus of the present invention. A video tape recorder (VTR) 2 is connected which extracts and reproduces arbitrary images. It is assumed that the VTR has the function of recording an address/index signal on the control track 9c of the video tape and searching for the address/index signal on the control track 9c. This connection type can be wired or wireless,
Can be remote controlled. Reference numeral 3 denotes an operation panel on which various operation switches necessary for users such as doctors, nurses, and technicians to perform ultrasound imaging, recording, playback, etc. are arranged. In this embodiment, the operation panel 3 displays patient information 8 such as the patient ID or patient name on a portion of the image 7, as shown in FIG. used for input. This patient information is entered when starting ultrasound diagnosis of the patient or when reproducing desired images from this videotape. 4
When patient information is input through the operation panel 3 as described above, the CPU (Central Processing Unit) creates address information to be recorded on the videotape using a preprogrammed method based on this patient information. Store in memory.

Reference numeral 5 denotes a program storage circuit, which is composed of a memory and is used to store the program, and when patient information is inputted by key operation from the operation panel 3 under the control of the CPU 4, the program storage circuit 5 stores the program. Stores the address information created by

Reference numeral 6 denotes a VTRTR control interface which uses the address information as the control base of the CPU 4 when the VTR 2 connected to the ultrasound diagnostic apparatus 1 is operated to record an ultrasound image of a patient. is converted into a predetermined control format and recorded as an address signal on a control track on the video tape. Also, if the image mode is changed while the VTR 2 is in the recording state, this interfunis circuit 6 will
Under the control of the CPU 4, the VTR is controlled to record index signals corresponding to images in image modes such as B mode, M mode, B/M mode, and D mode.

In this manner, when an address signal corresponding to patient information or an index signal corresponding to an image mode is outputted from the interfunication circuit 6 to the VTR 2, the VTR 2 records the information at a predetermined position on the videotape.

Next, the operation of this embodiment will be explained.

When recording ultrasonic images of each patient on a videotape of the VTR 2, by inputting each patient's information by operating keys on the operation panel 3 in advance, the interfunis circuit 6 generates an address signal corresponding to this patient information. ADD
Engineering, ADD2゜ADD3. ... are recorded on the control track 9C of the video tape 9 as shown in FIG. This address signal ADD1. ADD2, ADD3.
. . . correspond to patients a, b, c, . . . , respectively.

Next, when playing back this videotape and displaying images of a desired patient, input the patient information of the desired patient by operating the keys on the operation panel 3 in the same way as when recording. The address signal, for example ADD2 corresponding to the patient's seat, is retrieved under the control of the CPU 4. This retrieval is performed at a high speed equivalent to normal fast-forwarding and rewinding nine times, and at the moment the retrieval is completed, the cue of the patient is played back as shown in FIG. Therefore, just enter the required patient information,
This patient's image can be quickly retrieved and played back.

Furthermore, when an index signal corresponding to the image mode of each patient is recorded on a videotape in advance, this index signal, for example, I
This ADD2-
IND is searched under the control of the CPU 4. Therefore, the moment this is retrieved, the B-mode image of the patient is cued and played back as shown in FIG.

According to this embodiment, when recording an ultrasound image, if an address signal corresponding to the patient information of the desired patient or an index signal corresponding to the image mode is recorded on the videotape in advance, During playback, by searching for the address signal or index signal, a desired patient image or a desired mode image can be retrieved and played back at high speed. Therefore, there is no need to perform playback based on the tape counter value as in the past, so there is no possibility of failing to record the value or losing the recording paper, etc.
No more wasting time.

Therefore, it becomes possible to efficiently reconsider and remeasure diagnostic images.

As a modification of this embodiment, in a hospital or the like where patient information such as patient ID, patient name, etc. is not input, high-speed cue playback can be performed by simply recording only the index signal on the videotape. In such a case, cue playback based on patient information and cue playback based on image mode will coexist;
By controlling this, you will be able to achieve your goals without any problems.

Furthermore, when the number of (number of patients) x (number of image modes) to be recorded on one videotape is small, more detailed address codes can be performed by assigning addresses to the image modes as well.

For example, as shown in Figure 5, the patient ID is used as address information.
When the code is 4 digits 8354, the last 3 digits are 354
3541 can be set as the address code by combining the code 1 of the M mode as the image mode.

In addition, in the explanation of changing the image mode in the example, without generating an index signal when changing the image mode, the index signal is generated only at the point where you want to cue during playback (for example, the leading edge of the image mode that is frequently used for re-measurement). By creating a program to generate a signal, more efficient cueing can be achieved.

[Effects of the Invention] As described above, according to the present invention, patient information or image mode information is recorded on the videotape at the time of image recording, so that images of a desired patient can be cued and played back at high speed during playback. Therefore, the desired image can be played back without wasting time.
