According to the diagnosis of general telemedicine images and timely consultation of second-party experts, it is an important topic in modern clinical emergency medicine. Timely transfer medical images of emergency patients, such as static computed tomography (CT), nuclear magnetic resonance (MR) images, and dynamic ultrasound (US) videos to mobile phones from experienced specialists who are not in the hospital. Time and ground restrictions for remote diagnosis.

Telemedicine imaging consultation can improve the quality of medical care for remote patients and solve the problem of lack of manpower for remote specialists.

Clinically, a patient's medical imaging diagnosis is often a series of multiple files. For example, CT/MR in the brain of a suspected stroke patient requires up to 10 to 30 images from different angles. A 5-minute heart ultrasound film, file size can reach 500M Byte size; to transfer so many large files to mobile phones, facing the current IT technology challenges.

The efficiency of medical digital image transfer protocol image (DICOM) transmission is limited by the network The bandwidth and size of the image file. In addition, browsing medical images on mobile phones is also limited by the speed of the mobile CPU processor and different mobile operating systems.

However, the actual use of mobile phones The 3G and 4G wireless networks transmit and receive files, which are often limited by the number of people on the line and the stability of the wireless network distance of the mobile phone. The file downloading and uploading speeds often change drastically. During the transmission of a series of multiple medical image files, they will experience different bandwidth speeds, sometimes fast, sometimes slow, compressed JPEG 2000, medical image files, in the mobile phone receiving process, sometimes not It is faster than the original medical digital image transmission agreement image file, and it has not achieved the expected results. In addition, the compressed JPEG 2000 requires more calculation steps and time. For example, as shown in Table 1, it is an average thread download and resolution time (10 sheets each time, 10 times of test times), single Threaded compression JPEG 2000 image transmission and analysis did not perform as expected. The overall image and resolution was affected by JPEG 2000 decoding, making the speed slower than the Medical Digital Image Transfer Protocol (DICOM).

JPEG 2000 can solve the image demand storage space of medical digital image transmission protocol. It has too many shortcomings. It is used to transmit computer WiFi, cable network storage, generation and transmission, and performance is very good. There are also some imaging instruments, such as microvascular photography, ultrasonic wave starts. Adopt JPEG 2000 format. However, there are still many technologies that need to be broken through the use of mobile phones as diagnostic and consulting for telemedicine imaging.

Therefore, in order to improve the above-mentioned lack, the inventor of this case devoted himself to research and developed a "A method for accelerating the analysis of telemedicine image transmission" to effectively improve the shortcomings of the application.
