Method for communication and indication of interactive iatrology image

Abstract

An interactive medical image communications and display method which is based on JPEG2000 compressed data package transmission; the method uses the superior performance of JPEG 2000 compressed algorithm, and with the method, the JPEG 2000 compression process is implemented on the medical image in the pattern based on subsections; in this way, only the partial data package corresponding to image windows which client terminal is interested in rather than the entire image data is transmitted under the client/server environment and the client terminal could extract and display the medical image interactively based on the image content according to requests. With the invention, high-resolution DICOM medical image can be transmitted and displayed in real time fast and efficiently through WAN even when the bandwidth is limited to realize fast share of medical image information between PACS systems in different areas and hospitals; with the invention, medical resource can be effectively utilized, and the medical treatment effect, quality and efficiency of clinic activities such as long-distance consultation can be promoted.

Description

Technical field: [0001] The invention relates to information communication and computer image processing technology, in particular to an interactive medical image communication and display method based on JPEG2000 compressed data packet transmission. Background technique: [0002] With the digitization of various medical information and the widespread use of the Internet and related technologies, regional collaborative medical care and two-way referral are gradually being implemented and practiced. The medical diagnosis and treatment activities based on digital medical information for patients have gone beyond the scope of a hospital. It is necessary to transfer various medical information of patients among multiple hospitals in a certain area (or within a hospital group), so as to provide patients with continuous and consistent coordination. Medical services to improve the level of medical diagnosis and treatment, reduce possible medical accidents, reduce repeated inspectio...

Problems solved by technology

[0003] The main bottleneck in realizing the rapid sharing and exchange of patient medical image data between PACS systems in different hospitals is that medical images have high resolution (≥2000×2000, such as CR, DR, Mammography, etc.), large volume (≥60-400MB , such as MR, CT, US Series, etc.), and the data transmission rate of the wide area network is limited. Therefore, under the premise of ensuring the quality of medical diagnosis, these high-resolution medical images can be transmitted, displayed and processed efficiently, quickly and in real time. difficult to implement perfectly

At present, there are some systematic solutions. For example, teleradiology clinical consultation and consultation systems mostly adopt the method of pre-transmitting images and making appointments for consultations. Images need to be transmitted in advance for 4 to 24 hours before consultations. The limitations of this method It is impossible to access the images in the remote PACS system online and in real time, and the diagnosis process is complicated and the efficiency is low; Wireless transmission and display of high-resolution DICOM medical images" proposes a way to access high-resolution medical images by using JPEG2000 tiles (Tiles) data transmission. This method uses tiles to divide images, and each Each splicing block is independently compressed and encoded. In the network, it is necessary to transmit all the splicing block data covered by the region of interest of the client. The amount of transmitted data is large, and the access to image data is not flexible enough and the efficiency is not high. It can only be displayed on the client. local image data
