1. A medical imaging system comprising: at least one medical imaging device providing image data having multiple dimensions identifying physiological characteristics of a patient; an electronic memory receiving the image data; a plurality of first rank machine learning modules for receiving input data and providing output data based on predetermined weights; allocator circuitry dividing the received image data into a plurality of blocks associated with different subsets of the dimensions of the image data, the blocks provided to each of the first rank machine learning modules as input data; and a combiner receiving output data from the first rank machine learning modules and combining it to provide an output providing a diagnosis based on the image data; a display receiving the output to present a diagnosis; wherein the predetermined weights of the first rank machine learning modules are produced by separately training the plurality of first rank machine learning modules with a training set limited to the same subsets of the dimensions of the image data processed by the first rank machine learning modules.
