Hugh Harvey & Eric J. Topol –

Since the discovery of x-rays by Wilhelm Röntgen in 1895, scientists have been able to capture images of the human body with ever increasing clarity. Technology has evolved to the point that a full body CT scan can be taken in a matter of seconds at a lower radiation dose than would typically be received from about 3 years of natural background radiation. The main driver of this progress is the principle of reducing radiation dose, known as ALARA (as low as reasonably possible). Artificial intelligence (AI) has the potential to further reduce ionising radiation dose for imaging modalities that require it, such as x-ray, CT, and nuclear imaging.
