PACS, or Picture Archiving and Communication System, is a medical imaging technology used to securely store and digitally transmit patient images. It allows healthcare professionals to access and share images such as X-rays, CT scans, and MRIs quickly and efficiently, improving patient care and diagnosis. By eliminating the need for physical film, PACS enhances workflow in medical facilities. It provides tools for image manipulation and analysis, enabling radiologists and other specialists to collaborate more effectively. Overall, PACS plays a crucial role in modern healthcare by streamlining the management of medical images.
