1. A method comprising:
receiving measurement data acquired by an imaging device;
flattening the measurement data;
selecting a decimation strategy based on a size of the measurement data;
producing a reconstructed image from the flattened measurement data using the decimation strategy and a plurality deep neural networks, where the selection is further based a size of an input layer of the plurality of deep neural networks;
decimating the measurement data according to the decimation strategy to produce at least a first decimated measurement data array and a second decimated measurement data array;
mapping the first decimated measurement data array to a first decimated image data array using a first deep neural network;
mapping the second decimated measurement data array to a second decimated image data array using a second deep neural network;
aggregating the first decimated image data array and the second decimated image data array using an aggregation network to produce an image data array;
reshaping the image data array to produce the reconstructed image; and
displaying the reconstructed image via a display device.
