Abstract: A method, system and article of manufacture is disclosed. The method includes providing a spatial navigator outside of a thermal therapy region; receiving a plurality of analog-to-digital conversion (ADC) readouts from an MRI device at a plurality of time points, wherein the ADC readouts comprise a first ADC readout acquired at a first time point, and one or more additional ADC readouts acquired at subsequent time points; processing the ADC readouts to obtain a frequency of the spatial navigator at each of the time points; obtaining a main magnetic field (B0) drift of the MRI device based on the frequency of the spatial navigator at a particular time point and the frequency of the spatial navigator at the first time point; and obtaining the temperature change at the particular time point based on the B0 drift.

Abstract: A method is described for synchronously processing and rendering digitized media data streams where each data stream is made up of a sequence of samples. The described method includes processing each data stream in a single task. The method includes the generating the timing signals for different data streams from a single operating system timer and further processing the media in the data stream synchronously in one task using this timing signal.
