One aspect of the present invention is directed to an apparatus for generating
an image using an algorithm. The algorithm has a plurality of tasks for determining
the level of energy emanating from a source located within a mass. The apparatus
comprises memory configured to store information defining a trace. The trace defines
energy levels recorded at a sensor. The amplitude of the trace at one or more given
instants of time is the sum of energy received from two or more sources. A data
processor is in electrical communication with the memory and the data processor
is configured to simultaneously execute two or more tasks of the algorithm and
determine the level of energy emanating from each source.
