PACS eliminates the physical and time constraints associated with traditional film-based image retrieval, distribution, and display. Furthermore, it can handle images from various medical imaging instruments such as ultrasound, MR, positron emission tomography, CT, and so on.
A Picture Archiving and Communication System (PACS) is a computerised method of replacing the roles of traditional radiological film: images are acquired, stored, transmitted, and displayed digitally. When such a system is installed throughout the hospital, a filmless clinical environment is created.
