Biomedical images of both anatomical structure and real-time changes in neuronal, metabolic, positional, and vascular function in humans and animals is described. Ultra-wideband (UWB) pulse or square wave generators and electrical samplers, implemented using integrated circuits are used to make arrays of miniaturized microwave modules that are placed around the portion of interest in the body or head, allowing images to be made through either time-domain transmission of these pulsed waves through the body, or time domain reflectivity of the waves from internal structures, or their combination. Signal processing separate and extract the time-varying functional information from the static structural image data. The time-varying functional information from certain brain regions can be interpreted in order to control prosthetics, Brain-Machine-Interfaces and the like.
