Problems solved by technology

[0010] However, with the development of imaging equipment, the number of examination images is increasing. A CT examination has more than 1,000 images. It usually takes a few minutes for doctors to retrieve images from the imaging center, which seriously affects the efficiency of diagnosis.

Embodiment Construction

[0026] Describe an embodiment below in conjunction with accompanying drawing, the present invention is described further.

[0027] figure 1 Shown is a basic data encoding block. When the server parses the image, it will encapsulate the image data stream according to the above format; where the PDU type represents the command type or data type, and the PDU length represents the length of the data block, that is, how many bytes the data stream has, and the subsequent data block is an encapsulation The PDV block, the PDV block contains the length of the item, that is, the length of "presentation layer data (PDV)-data set information", and the syntax ID of the presentation layer is the transfer syntax used by the image. The transfer syntax mainly includes reading from the high byte and Read data stream starting from low byte. The data encoding has some innovations on the old encoding format—designing a large PDV block containing multiple small PDV blocks.

Abstract

The invention relates to a medical imaging calling-reading optimizing method based on a multithreading technology. By the method, a mature unlimited connection technology is built by using a multithreading point-to-point method, a CPU (central processing unit) can be operated fully when needed by a user, a condition that one-time connection is built for a single image is changed into another condition that one-time connection is built for a sequence of images, so that excessive hand shaking times can be reduced, one-time hand shaking can be used for a plurality of times, and a client side can be used for downloading the images in a multithreading way, so that I / O performances are fully used. Due to the method, the difficult problems in the current basic medical imaging calling-reading method are solved, the method is particularly applicable to an imaging teaching system which is large in image detecting number and slow in transmitting speed and requires consulting for multiple times, such as the images of CT (captive test) and MR (magnetic resonance) types, therefore, the consulting times are obviously reduced and the transmitting speed is increased.

Description

technical field [0001] The invention relates to medical image communication and transmission technology. Background technique [0002] PACS (Picture Archiving and Communication System) image archiving and communication system is currently a computer and network technology applicable to medical technology departments in hospitals in radiology, ultrasound, endoscopy, pathology, nuclear medicine and other imaging examinations. It is used by hospitals to replace traditional business way of technical means and business models. [0003] The existing image retrieval methods are: [0004] 1. Coding method. Encapsulate the image stream into multiple PDV files. When encapsulating data, the image stream needs to be encapsulated into PDV data blocks one by one according to the fixed PDV length. Each PDV includes the item length, presentation layer syntax ID and data stream; [0005] 2. Single-threaded analysis of image data. Before sending the image, analyze it first, then send the ...
