TRAGBARES ULTRASCHALLSYSTEM FÜR EFFIZIENTE ABSCHALTUNG UND ANFAHREN

摘要

An ultrasound system is described which can be turned off quickly and restarted to be ready for scanning in a matter of seconds. This is accomplished by allowing a processor and/or memory within the system to remain active even when the system is "turned off." When the system is turned off the state of the system is minimally preserved in either volatile or nonvolatile memory so that the system can quickly restart without having to sequence through an entire bootup procedure.
