Ris

1. Reconfigurable Intelligent Surfaces (RIS) in Telecommunications

In medicine, an RIS is a core software system used by radiology departments to manage patient data and the workflow of medical imaging. It acts as the "brain" of the department, coordinating with the (Picture Archiving and Communication System) to store and retrieve images.

: Because RIS elements are passive—meaning they do not require power-hungry radio frequency (RF) chains—they consume significantly less energy than traditional relays.
