Smart cloud system with image processing server in diagnosing brain diseases dedicated for hospitals with limited resources

The use of medical imaging in diagnosing brain disease is growing. The challenges are related to the big size of data and complexity of the image processing. High standard of hardware and software are demanded, which can only be provided in big hospitals. Our purpose was to provide a smart cloud system to help diagnosing brain diseases for hospital with limited infrastructure. The expertise of neurologists was first implanted in cloud server to conduct an automatic diagnosis in real time using image processing technique developed based on ITK library and web service. Users upload images through website and the result, in this case the size of tumor was sent back immediately. A specific image compression technique was developed for this purpose. The smart cloud system was able to measure the area and location of tumors, with average size of 19.91 ± 2.38 cm2 and an average response time 7.0 ± 0.3 s. The capability of the server decreased when multiple clients accessed the system simultaneously: 14 ± 0 s (5 parallel clients) and 27 ± 0.2 s (10 parallel clients). The cloud system was successfully developed to process and analyze medical images for diagnosing brain diseases in this case for tumor.

A new femtocaching file placement algorithm for Telemedicine

A new femtocaching file placement algorithm is designed for Telemedicine to improve transmission of medical scan images via wireless networks. The experiments show that the proposed algorithm drops the delay compared to the Greedy algorithm and the baseline case. The experimental results also show that the proposed algorithm improves the capacity of the caching helpers and reduces the total delay of the daily operations in healthcare facilities.

DicomWorks Teleradiology: secure transmission of medical images over the internet at low cost

We developed a completely secured teleradiology solution tailored for e-mail teleradiology applications at low-cost. Data processing consists in creating a couple of files with an encrypted and compressed image archive and a 128 bits decoding key file. No proprietary file format or encryption scheme is used. Files are exchanged using the e-mail (SMTP and POP) protocols, but FTP or sFTP can be used for better performances. Software includes original features such as real-time interactive JPEG compression, instant archive preview or secured data cleanup when a user logs off. We believe that this flexible, integrated and easy to use solution is a robust alternative to more complex architectures for simple image transmissions or occasional circumstances.
