Abstract:
A system and method for transforming ultrasound data includes acquiring ultrasound data, calculating object motion from the data, modifying a processing parameter, processing the ultrasound data according to the processing parameter, and outputting the processed ultrasound data. The system and method may additionally include the calculation of a data quality metric that can additionally or alternatively be used with object motion to modify a processing parameter.
Abstract:
The invention is directed at a method and system for flexible rate processing of ultrasound data. In one embodiment, the method includes acquiring ultrasound data at a data acquisition rate; setting an inter-frameset data rate; selecting frames from acquired ultrasound data to form a plurality of framesets, where the framesets are spaced according to the inter-frameset data rate; and processing the data at the controlled data rates. In another embodiment, the system includes a data acquisition controller that collects ultrasound data at an acquisition rate; a memory that stores the ultrasound data; and a data processor that selects framesets at an inter-frameset data rate, wherein a frameset is a set of frames selected from memory, performs processing on a frameset, and outputs processed data at a product rate.

Abstract:
Mechanisms and techniques for database fragment cloning and management are provided. A database object, such as a table, rowset or index, is divided into fragments. Each fragment is cloned to create cloned fragments, which operationally are substantially identical to one another. One or more of the cloned fragments may be designated as a primary cloned fragment for performing database operations or as a secondary cloned fragment for serving as backup. Updates to each fragment are implemented on the primary cloned fragment and are then propagated from the primary cloned fragment to the corresponding secondary cloned fragments. A cloned fragment can go offline, becoming unavailable to be updated. When the cloned fragment returns online, the cloned fragment is refreshed with data included in the primary cloned fragment. While being refreshed, the cloned fragment may continue to be updated. The cloned fragment is eligible to be designated as a primary cloned fragment when the refreshing process has been completed.
