A freestanding image processing device that is a component of radiation therapy treatment planning configuration. It is sometimes considered to be a component of a picture archiving and communication system (PACS) or a local area network (LAN) configuration, e.g., a radiology information system (RIS) or hospital information system (HIS). It does not contain any controls for the direct operation of a radiation therapy system. It can receive and transmit data both on-line and off-line and is configured to provide the capability to remotely process, manipulate and view patient images and information used in treatment planning, record and verification.
