Description

[0001] The present invention relates to a method and system for transmitting medical image data in an embedded multi-platform environment,

The present invention relates to a DICOM medical image transmission and processing method and system thereof in an embedded multi-platform environment, and more particularly, to a DICOM medical image transmission method, a DICOM image overlay server The present invention aims to provide a digital image processing apparatus capable of dividing and transmitting diacom medical image data through an overlay network so that diicom medical images can be quickly transferred on a network. In the diacom medical image processing method, The original medical image data is converted into a dicom size reduced medical image having small size data, and during the dicom image conversion process in the embedded terminal, the dicom size reduced medical image data having a small data size in the Pax server Provided as terminal canvas and displayed After completing the image modification process, the original medical image data of the DICOM is provided and displayed on the terminal canvas according to the DICOM image deformation value in the PXSS server, so that quick image processing of the DICOM medical image is performed in the environment of the embedded terminal To be able to do so.

Generally, in a hospital, medical imaging devices such as endoscopes, CT, MRI, and ultrasound are acquired and stored in a digital state, and functions necessary to transmit and retrieve the readings and medical records to each terminal together A digital image storage and transmission system (PACS), which processes the digital image data in an integrated manner, is being applied.

PACS (PACS) has been able to improve the hospital work capacity by efficiently processing the hospital's diagnosis and reading through the existing film through the computer and network, so that it can be done efficiently.

Meanwhile, since the image of the medical digital image used in the PACS, that is, DICOM (Digital Imaging and Communications in Medicine) medical image, has a high resolution, the transmission delay on the network, It takes a lot of time for image transformation process such as size and level, so that downloading of images and image transformation process are not performed quickly.

In addition, when Daicom medical image data transmission is dependent on only Daikom medical image files stored in the Pax server, there is a problem that the speed is not increased any more when the network bandwidth of the Pax server is exceeded. When many embedded terminals are connected, n, the speed is divided by 1 / n, so that the speed is decreased and the number of servers and lines is increased by hardware, which causes an exponential increase in cost.

To overcome the shortcomings of the network transmission rate and reduce the burden on the server, P2P Overlay Network technology, which combines P2P technology with Overlay Network concept, can be used. Unlike the existing Client / Server concept, P2P technology is characterized in that all the participants are servers and simultaneously perform the dynamics of the client to reduce the burden on the server. Overlay Network can provide efficient network service by constructing a virtual network on top of existing network.

In addition, as various OSs emerged, the demand for software operating in an embedded environment rapidly increased. However, in order to develop software in each development language corresponding to various multi-platforms, a huge development cost and time were consumed.

Therefore, a web page language such as HTML5 is an effective language that can reduce development cost and time in various multi-platform environment of an embedded terminal. Since it is easy to apply in various multi-platforms, it can be applied to various platforms with one development, Thereby shortening the cost and time of the system.

Especially, among the web page languages, HTML5 is the latest standard of HTML and it is a core markup language of the World Wide Web. In the existing version, it can realize brilliant graphic effects that could not be used without ActiveX or Flash, and can realize fantastic multimedia on web pages.

The HTML5 canvas also allows image processing to be done directly on the Web page by processing the image data directly, and the HTML5 canvas allows developers to express a great level of graphics in a web browser in a common language such as HTML or JavaScript.

This image processing enables the transmission of medical images and various image processing in a variety of multi-platform environments, allowing the user to adjust the window size or window level (Window Width / Level) function, which is useful for accurate determination of medical images, It allows you to manipulate the level arbitrarily.

However, in the HTML5 canvas, it is a big problem that the processing speed of large size images like Dicom original medical images is significantly lower than that of native technologies (C, C ++, C #, Java, etc.). In particular, when the window size and the window level control function are required to display the converted image in real time, the problem of the image processing speed is adversely affected because a large size image must be processed several times. In addition, there is a problem that the image processing performance is significantly lowered in an embedded terminal device having a hardware performance restriction than a general terminal.

Korea Patent No. 0932195

Accordingly, in the embedded terminal environment using a web page language such as HTML5, as described above, due to the limited transmission rate and slow image processing speed of the existing network, So that it is possible to solve the problem that the window size and the window level can not be manipulated quickly and easily.

That is, the present invention provides a method of transmitting and processing a medical image in a multi-platform embedded environment, the method comprising: transmitting a large-capacity original digital image data to a Fox server using a P2P overlay network between the embedded terminals, The image data is converted into a dicom size reduction medical image adjusted to have small size data, and during the dicom image conversion process in the embedded terminal, the dicom size reduction medical image data having the small size data transmitted from the pax server Is displayed on the terminal canvas, and after the image modification process is completed, the DICOM original medical image data is displayed on the terminal canvas according to the diCOM image deformation value.

According to another aspect of the present invention, there is provided a DICOM medical image system in an embedded multi-platform environment, the DICOM medical image system comprising: a PICKS server that stores a DICOM original medical image and transmits the DICOM original medical image to an embedded terminal connected through a network; An original medical image data unit which is provided in an embedded terminal and a Pax server for displaying an image and stores DICOM original medical image data, DICOM original medical image data stored in the DICOM original medical image data unit is a P2P overlay network The original medical image data is converted into a reduced size data, and the converted digital image data is stored in the decompressed medical image data portion and the embedded terminal to display the original medical image of the DICOM. Consisting of a terminal canvas The.

Therefore, in transmitting and displaying the DICOM original medical image displayed on the canvas of the embedded terminal, the DICOM original medical image data transferred from the PACS server to the embedded terminal is converted into small-sized data, As a result, the original medical image data of the actual Dicom after the completion of the image conversion process by the user is distributed by using the P2P overlay network to distribute the medical image data Real-time image processing such as window size and window level adjustment is easily and clearly performed.
