The artificial neural network (ANN)-a machine learning technique inspired by the
human neuronal synapse system-was introduced in the 1950s. However, the ANN was
previously limited in its ability to solve actual problems, due to the vanishing
gradient and overfitting problems with training of deep architecture, lack of
computing power, and primarily the absence of sufficient data to train the
computer system. Interest in this concept has lately resurfaced, due to the
availability of big data, enhanced computing power with the current graphics
processing units, and novel algorithms to train the deep neural network. Recent
studies on this technology suggest its potentially to perform better than humans
in some visual and auditory recognition tasks, which may portend its applications
in medicine and healthcare, especially in medical imaging, in the foreseeable
future. This review article offers perspectives on the history, development, and
applications of deep learning technology, particularly regarding its applications
in medical imaging.
