A Picture Archiving and Communication System (PACS) is a medical imaging technology that stores, retrieves, and shares images such as X-rays, MRIs, and CT scans. It replaces traditional film-based methods, allowing healthcare professionals to access images digitally, improving efficiency and patient care. PACS enables seamless communication between different medical departments and facilities. By using a secure network, doctors can quickly view and analyze images from various locations, facilitating timely diagnoses and treatment decisions. This system is essential for modern healthcare, enhancing collaboration among radiologists, physicians, and other medical staff.
