Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] exist figure 1 In the shown embodiment, the image decompression of the adaptive display system interacts with the doctor's operation information, and the display and processing modules respond to the user's operation information on the display interface. The system designs a special display strategy control module for JPEG2000 images, and dynamically adjusts the code of the current image. Stream extraction decompression step. The JPEG2000 adaptive decoding module and the JPEG2000 code stream extraction module perform data communication through the shared code stream buffer. The former extracts the image code stream data from the shared buffer according to the display strategy for decompression, and the latter extracts the code stream data from the PACS server through HTTP. into the shared buffer.

Abstract

The invention discloses a self-adapting extraction and display method for JPEG2000 medical images which enables the client, in terms of network bandwidth resource, image browsing layout and clinician operation information, to self-adaptively adjust the image extraction and display manner in real time, improve current image extraction and display mode and to efficiently provide high-resolution image for the clinician step by step by utilizing superior characteristics of JPEG2000 compression algorithm and adopting priority encoding mode for important image data. The method enables the clinician to quickly acquire images of the patient and to obtain high-resolution images in time when the network bandwidth is unsteady or bottlenecked, thereby improving diagnose efficiency and serving more patients with limited medical condition.

Description

Technical field: [0001] The invention relates to the fields of information communication, computer and medical technology, in particular to a medical image adaptive extraction and display method based on the JPEG2000 standard. Background technique: [0002] With the rapid development of digital imaging technology, the problems in image storage, transmission and display of medical picture archiving and communication system (PACS) system have gradually emerged. The volume of medical images generated in various clinical diagnosis and treatment is getting larger and larger. For example, a CR / DR X-ray chest digital image is about 10MB; conventional CT images often have dozens or hundreds of images in a patient series The image is tens of MB, and the multi-slice CT image (heart) examination has nearly a thousand pieces (about 1GB). In hospitals, the images stored and managed by the PACS system increase in a massive manner (for example, in a top-tier hospital with 1,000 beds, the ...
