Remote medical image analysis

The Remote Medical Image Analysis System implements a process for providing computerized medical image analysis for medical service providers using an Application Service Provider [ASP] model. To analyze a medical image, the system accepts a medical image file from a remotely located user. The medical image file is transferred over a computer network, such as the Internet, wherein the system analyzes the medical image file. The analysis results (which may include transformed images, reports, and diagnoses) are then transferred by the system to the user over the computer network. To accomplish this task, the system implements web servers, application servers, and processing servers, with data servers utilizing a database for data storage and retrieval, coordinating data flows among the various servers and system users and archiving data for longer-term storage.
