Abstract
Architectural changes with Tianyi cloud storage of China Telecom were made to the up/down loading of the image-text mega data created in the picture archiving and communication systems(PACS)of the hospital.Thanks to the changes, the data volume uploaded by the PACS of the hospital reached 160G per day, with average upload speed up to 5.3M/second; supporting online query of all image-text data of patients.The authors hold cloud storage technology as safe and reliable, and such other merits as supporting data encryption, automatic offsite redundancy, almost online real-time read/write access, almost infinite extendibility, fast self-healing and off-site disaster-tolerant backup. Key words: Picture archiving and communication systems(PACS); Mega data; Imaging center; Cloud storage; Security
