Abstract:
An ultrasound control unit (12) is for configuring visualization of ultrasound data using in use a display unit. The control unit is adapted to acquire ultrasound image data and to automatically control visualization of the most relevant parts and views the data, based on current levels of a number of different monitored physiological parameters. In particular, responsively to one of the physiological parameters entering or leaving a pre-defined range of values (e.g. representative of an alert or normal condition respective for the patient), the control unit determines a most appropriate anatomical region within the image data for representing the changed physiological parameter, and a most useful visualization mode (e.g. view) for presenting or showing that anatomical region within the image data. One or more display frames are generated which show the anatomical region visualized in accordance with the selected visualization mode. A control output is generated for controlling a display panel to display the one or more display frames.

Abstract:
A system (100) is provided for processing status information of a medical device (020-023). The medical device performs a medical function at a bedside of a patient and is arranged for generating an alarm signal (030) to alert a caregiver of the patient to an occurrence of an event which is associated with the performing of the medical function. A status interface (120) acquires a device signal (024) of the medical device, the device signal comprising status information which is indicative of a current status of the performing of the medical function. Moreover, an analysis subsystem (140) analyzes the status information to estimate an imminent occurrence of the event based on said current status, and a notification subsystem notifies the caregiver of the imminent occurrence away from the bedside of the patient of the event by a generating a notification signal (162) for a notification device (060- 064). The priority of notifying the caregiver is based on an estimate of whether the patient is asleep. The system enables the caregiver to be notified about the event ahead of time, i.e., before the event occurs and thus before the medical device generates an alarm signal. Advantageously, the patient is less disturbed by alarm signals during sleep.

Abstract:
The invention provides an ultrasound processing unit. A controller (18) of the unit is adapted to receive ultrasound data of an anatomical region, for example of the heart. The controller processes the ultrasound data over a period of time to monitor and detect whether alignment of a particular anatomical feature (34) represented in the data relative to a field of view (36) of the transducer unit is changing over time. In the event that the alignment is changing, the controller generates an output signal for communicating this to a user, allowing a user to be alerted at an early stage to likelihood of misalignment and loss of imaging or measurement capability.
