Abstract: Without using ECG input signals or processor intensive correlation, cyclical timing is determined from ultrasound data. Cyclical timing includes determining the time of end diastole, time of end systole or heart rate. The ultrasound data is reduced, such as by projecting each frame of data onto two axes. For projection, data is summed along each dimension. The location associated with the maximum variance through the sequence is identified from the projected data. The ultrasound data associated with the location is used to identify cycle timing information, such as to provide a waveform representing the cycle. Lines from different frames of data in the sequence are also used to generate an image. The image shows cycle timing information.

Abstract: An application interface provides an environment in which applications may discover and attach to data streams. The interface facilitates efficient sharing and management of acquired data through arbitration and parallel processing: allowing multiple applications to work in parallel on the same or different data streams to implement independent or co-dependent functionality. Further, the interface acts as a bridge between system address spaces allowing applications to execute in their own address space separate from the resource intensive acquisition processes. The interface also provides an environment for prototyping applications where a user may allocate data streams to an application and debug the application's execution. Because the interface provides a standardized/normalized interface to the acquired image data, applications may be developed independent of the imaging system's implementation details, data formats and protocols.
