  • Information encoding for enabling an application within a different system/application in medical imaging
    Patent number: 8201186
    Abstract: Methods and system for data/process sharing between different systems. A trigger response unit is deployed on a first system where a first application resides. The trigger response unit is to detect when a representation corresponding to trigger data from a second application is present in the first application. When such a presence is detected, the detected representation corresponding to the trigger data is decoded to obtain a trigger, wherein the representation encodes the trigger corresponding to the second application and information associated with data. Based on the trigger, the first system launches the second application within the first application on the first system by utilizing the trigger data that include a trigger pattern present in a trigger image.
