The results of development of this system and its usage in clinical practice suggest that practical usage is fully possible and that this system may be very useful in the medical field.

In recent years, information technology (IT) in medicine is progressing remarkably. But we do not have any good tools for access to medical images from outside hospital. Therefore we set up 3D cloud server for provide real-time diagnostic imaging for their patients. I report demonstration test for practical use in December 2011 to March 2012.

We set up 3D cloud server with virtualization application system for create 3D images. Image transfer speed testing involved measuring the image transfer speed in-hospital to the cloud-based server and transmitting 250–5000 images worth of 3D image data (computed tomography [CT]) to the cloud-based server and varying the number of images, parallel load, and other aspects to analyze the actual time required. For including the actual usage assumptions, we used frames per second (FPS) measurements, wireless LAN, and WiMAX (Worldwide Interoperability for Microwave Access) for ordinary 3D creation processes to investigate the feasibility of processing in terms of the differences in operability.

The transfer speed was equivalent to when the server system was installed inside the hospital (11.4 images/s in-hospital, 10.2 images/s with the server). The FPS was the highest in-hospital, at 17.8 frames/s and 16.5 frames/s with the server. Thus, we confirmed that FPS was within ranges that allowed for practical use in terms of operability.
