Picture Archiving and Communications Systems (PACS) have been developed for medical image acquisition, archiving, communication, retrieval, processing, distribution, and display. This project presents a Web-based prototype system that enables efficient access and manipulation of digital medical image data on a much wider scale and at much lower cost than conventional systems. The philosophy of this project is dividing PACS system into number of subsystems that work together to perform the essential functions of the PACS software and ensure the efficient distribution, storage, retrieval, and reporting of the images. These subsystems are integrated together and communicated through database-to-database transfer method. The complete structure of the system is modular structure that makes the project flexible and applicable. This means each one of the subsystems consists of number of the pluggable modules, allowing to add new features by coding them as separate modules and plugging them into the existing system. This makes it suitable for use in any hospital or medical center. The project had used the open source platforms to make use of their security, reliability, robust, support community, and finally the open source feature that makes them customizable and can be edited or modified by any developer. The software is implemented in PHP scripting language, which is embedded in HTML. Then the Server-side was achieved using My SQL (My Structured Query Language) for data storage. To ensure efficient management, all data and information are stored in a My SQL database.
