The available phenomena that can now be detected or propagated through living tissue for diagnostic imaging purposes include electromagnetic and particulate radiations, electric and magnetic fields and ultrasound each with advantages, disadvantages and fundamental limits. Diagnostic imaging of the future, influenced by increasing computing speeds, advances in computing software and digital transmission will provide improved facilities for the demonstration of disordered function, molecular diagnosis, minimally invasive therapy and improved control of cancer treatment.
