Abstract

A method and system for displaying historical as well as real time image data in a uniformed format is disclosed herewith. In an embodiment, the system makes assumptions of the users’ intention that are non-obvious. The right information in each case is selected based on the users’ actions and the data presentation seamlessly to the kind of information that needs to be displayed is adapted

A METHOD AND SYSTEM FOR REPRESENTING HISTORICAL AND REAL TIME IMAGE DATA

FIELD OF INVENTION

[0001]               The invention generally relates to image display methods and more specifically to a method and system for displaying historical and real time image data in a unified format. .  

BACKGROUND OF THE INVENTION

[0002]               The graphical user interfaces of modern physiological patient monitors separate real-time data presentation like waveforms from historical data like graphical and numerical trends.  The reason for this is technical compatibility, mainly: source of real-time data may be a physiological measurement module whereas source of historical data is a database residing in monitoring device’s memory.  

[0003]               Switching from viewing real-time data to viewing historical happens by pressing buttons (physical or on-screen) with labels like “Graphical trends” (e.g. one-minute-average data) or “Full disclosure” (beat-to-beat waveform data). 

[0004]               As caregivers are becoming more and more computer-literate it is likely that they have used computer generated map applications where viewing more detailed map happens by selecting the area to be zoomed or clicking “plus”-sign. Viewing larger area with less detail happens by clicking “minus”-sign or selecting larger scale using a slider control.  User interface remains the same at every level of details because zooming in and out is seamlessly integrated with the viewing.  Patient monitoring users would like to have similar user experience when viewing clinical data so that they could “fly-by” the graphical trend and when they detect something interesting zoom in on beat-to-beat waveform data and zoom out back to the overview as needed.

[0005]                It is difficult to navigate from one view to another while reviewing the images. Thus it is required to have a unified presentation method for historical as well as real time data.

SUMMARY OF INVENTION

[0006]               An embodiment of the invention provides a unified representation method for representing real time as well as historical data in an image display.  

[0007]               Generally deep knowledge of the needs of the patient monitoring users is needed to decide what information will be displayed in each phase of the above described use scenarios.  In an embodiment, the system described the invention makes assumptions of the users’ intention that are non-obvious. In one aspect of the invention, the right information in each case is selected based on the users’ actions and the data presentation seamlessly to the kind of information that needs to be displayed is adapted.

[0008]               The invention is explained using the following scenarios.  In following scenarios it is assumed that patient monitoring device support either a pointing device (e.g. mouse) or touch.  Some scenarios can also be implemented with push-and...
