Description

Medical image transmission method

The present invention relates to a method for transmitting a medical image, and more particularly, to a medical image transmission method suitable for transmitting a medical image from the server side to the client side in response to a client's request.

As is well known, a telemedicine system includes a server system that constructs medical information and medical images of a patient in its own database (DB), and a plurality of clients connected to the server system and each having an A / V terminal.

Therefore, in the server system, when there is a service request of a medical image for treating any patient from any client connected (or registered), the medical image and medical record data of the requested patient (patient personal record, disease name, date of onset, Process, wound area, etc.) is transmitted to the corresponding client through the RF cable, and the client side performs the corresponding treatment by referring to the received medical image and medical information.

Meanwhile, the medical image serviced by the server system as a client may be a still image or a moving image. In the case of a still image, a large amount of transmission data does not have much problem in real time processing. there is a problem.

In other words, when a video medical image is occupied with a lot of bandwidth, it is inevitably restricted to remote service for a large number of other clients, and is also appropriate when a quick judgment on a wound is required. There is a problem that can not respond. Therefore, there is an urgent need to develop a technique for effectively serving a medical image in a real-time concept, but currently there is no commercialized service technique that can cope with this.

Accordingly, an object of the present invention is to provide a medical image transmission method capable of real-time service of a medical image as a moving image using a gradual transmission technique of assigning priority to a region of interest. There is this.

In order to achieve the above object, the present invention provides a method for transmitting video medical information about a plurality of patients, which is built in a database on a server side, to a service request client among a plurality of registered clients. Constructing a medical information database using medical image information, audio information, and patient record information of a moving image; If there is a request for medical care information service for a specific patient registered from any of a plurality of registered clients, a medical image of the specific patient is extracted from the database, and a low-resolution image of the extracted medical image is generated to generate the low-resolution image. Transmitting to the service request client; Setting a region of interest in the extracted medical image based on the record information of the specific patient, generating location information together with a high resolution image of the set region of interest and transmitting the location information to the service request client; And checking whether there is a high priority bus request from the registered plurality of clients, and when there is no high priority bus request, transmitting a high resolution image for the remaining areas other than the ROI to the service request client. It provides a medical image transmission method consisting of a process.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a client server system suitable for applying the method for transmitting a medical image according to the present invention. The server system 100 includes a server 102, a database 104, and an interface block 106. And a client 200 with an A / V terminal 202, an interface block 204, and a monitor 206. In this case, although a plurality of clients are connected to the server system 100, only one client 200 is illustrated in FIG. 1 for convenience of description and enhancement of understanding.

Referring to FIG. 1, the server 102 includes, for example, a microprocessor, and the like, when a video signal, an audio signal, and patient record information of a patient photographed through a camera (or a digital camera) are provided. The data is stored in the database 104, and the transmission and reception of medical information (video information, audio information, patient record information, etc.) through the interface block 106 is performed in response to a request from the client 200.

In addition, the server 102 generates a low-resolution image of the medical image of the patient requested for service when there is a medical information service request for a certain patient from the client 200, and generates a region of interest based on the patient record information. ROI), for example, a region of interest, such as a wound site, is set, and priority is given to the set region of interest information to be transmitted in a high resolution image.

To this end, the database 104 stores and stores the medical information about the registered patient, for example, patient record information such as the patient's personal record, the name of the disease, the date of onset, the progress, the wound area, and the medical image (digital video). do.

On the other hand, the interface block 106, when provided with the patient information (for example, the patient name, etc.) and the client ID to perform the medical service along with the medical information service request message from the client 200, the server 102, When the digital medical information data (video image medical image data, audio data, patient record information data) is provided from the server 102 in response to the medical information service request, the client 200 ), The interface block 106 may employ, for example, a 1394 interface board that performs a high speed serial interface.

On the other hand, the A / V terminal 202 on the client 200 side is, for example, a personal computer. The A / V terminal 202 is, for example, a personal computer. The medical information (video information, audio information, patient record information) of the patient who requested the service from the server system 100 through the interface block 204, Multiplexing provides a video signal and patient record information data to the monitor 206, and provides a voice signal to a speaker not shown. Here, the interface block 204 is a board having the same structure as performing the same function as the interface block 106 provided on the server system 100 side.

Therefore, the medical person will perform the target medical service based on the medical image (video) displayed on the monitor and the audio signal provided through the speaker.

Next, a process of providing a medical imaging service according to the present invention using the client server system having the above-described configuration will be described.

2 is a flowchart illustrating a process of serving a medical image from a server side to a client side according to a request of a client according to a preferred embodiment of the present invention.

Referring to FIG. 2, in a state in which medical information (video information, audio information, patient record information, etc.) for a plurality of registered patients is formed into a database and built (stored) in the database 104 (step 202), the server 102 performs a standby mode that checks whether there is a medical information service from any registered (or connected) client (step 204).

The check in step 204 determines that there is a medical information service request from any client, i.e., the client ID and patient information (patient name, etc.) together with the medical information service request message via the interface block 106. When received, the server 102 extracts a medical image (video) of the selected patient from the database 104 to generate a low resolution medical image.

That is, as an example, as shown in FIG. 3A, an average value is extracted and selected for four pixel values of 2 × 2, or as shown in FIG. 3B, an average value for nine pixel values of 3 × 3. 3C, or as shown in FIG. 3C, a low-resolution medical image can be generated by extracting and selecting an average value for 16 pixel values of 4 × 4, and the like. The low resolution medical image data is transmitted to the service request client 200 side through the interface block 106 together with the voice information data and / or the patient record information data (step 206).

Thus, a medical image of low resolution (e.g., an image in which 4, 9 or 16 pixel values are filled with one average pixel value) will be displayed on the monitor 206 on the client 200 side.

In this case, when one average value is transmitted to four adjacent pixels, the amount of data to be transmitted will be reduced to about 1/4, and when one average value is transmitted to nine adjacent pixels, the amount of data to be transmitted is approximately 1/9. If one average value is transmitted to 16 adjacent pixels, the amount of data to be transmitted will be reduced to approximately 1/16.

In addition, the server 102 sets the ROI in the medical image based on the patient record information (wound area information, etc.), that is, the actual medical treatment in the entire medical image based on the wound area information stored in the database 104. For example, an area required for the service (such as a wound area) is set to a rectangular section (step 208), and the set ROI data (i.e., high resolution image data) is set to the location information (i.e., the upper left and the lower right of the rectangular section). Side coordinate value) to the service request client (step 210).

Therefore, the composite image of the ROI is a high resolution image and the other regions are the low resolution images will be displayed on the monitor 206 on the client 200 side. You will be able to perform your care quickly.

Meanwhile, after transmitting the high resolution medical image of the ROI to the service request client 200, the server 102 checks whether there is a bus request signal having a high priority from another registered client (step 212). In the case of the check in, if there is a high priority bus request, the bus is allocated to the client to provide the desired service (step 214). The medical image of the video of the remaining area (ie, the image area excluding the ROI) is transmitted to the client 200 (step 216).

As a result, a medical image having a high resolution as a whole will be displayed on the monitor 206 on the client 200 side.

As described above, according to the present invention, when there is a medical information service request from any registered client, the server side first transmits a low-resolution image of the entire medical image to the client, and then sets a region of interest (i.e., wound area, etc.). By adopting a gradual transmission technique that transmits high-resolution images for the high resolution image and transmits high-resolution images for the remaining areas when there is no high priority bus request, the medical imaging service of the video is realized in real time while maximizing the efficiency of using the limited bandwidth. It can be realized at high speed.
