Understanding PACS and Their Core Role in Modern Research

At it s essence, a PACS is a complesive system that acquires, stores, retrieves, Secretes, and displays medical images from modalities such as computed tomograph (CT), magnetic rezonance imaggy (MRI), digital radiographia, and ultrasund. Beyond simple archiving, modern PACS integrate with Radiology Information Systems (RIS) and hospic heate ctes (EHR), increating a unified workflow at suports both clinicar and research ch.
