The Research of Applying Parallel Streaming Technology on Developing Cloud Computing Platform for Delivering Medical Images

At present, most of medical facilities are using PACS (Picture Archiving and Communication System) to manage various medical images. PACS is a medical image management system and the main purpose of PACS is to replace conventional film with digital images and to allow medical professionals to view digital photographs or images of diagnostic tests, interpretations and related data simultaneously from multiple sites. In the paper we further propose a Cloud image data platform which is suitable for managing medical images. This platform collaborates with PACS in medical facilities and it immediately delivers images captured by equipment via parallel connection to remote server in form of parallel streaming. Taking advantage of parallel streaming technology, we have solved the medical resources sharing problem and problem caused at delivering and storing consecutive high resolution image files. Patients who are to be transferred to other medical facilities will no longer re-do all examinations. This saves medical resources and physician’s precious time. Our experiments shows our parallel streaming delivering platform improves the transmission efficiency on LAN (Local Area Network), TANet (Taiwan Academic Network) and home-group network by 45.6％, 49.4％, and 8.1％ respectively in comparison with conventional single server system using FTP transmission.
