In this project you are going to develop a web-based database application system, called Radiology Information System.  A Radiology Information System (RIS) is a computer information system that stores and processes the information for a radiology lab, including all the data regarding patients, and all medical images generated by various diagnostic and therapeutic equipments, such as X-ray, Computed Tomography (CT/CAT), Ultrasound (US), Magnetic resonance imaging (MRI). A Radiology Information System is optimally complemented with a Picture Archiving and Communication System (PACS).
