![]() ![]() The purpose of a rotating anode is to spread the heat produced during an exposure over a large area of the anode. X-rays are produced by the acceleration of electrons from a cathode source (made of tungsten) to an anode target (made of 90%tungsten/10% rhenium and can be a stationary or rotating target) with both collisional (>69.5 kVp) and decelerating interactions resulting in characteristic and to a greater extent, Bremsstrahlung radiation respectively. After more than a century of film and film screen imaging, the backdrop of diagnostic radiology has changed from hanging films on view boxes to LCD monitors. ![]() However, this expense will be well worth the investment from a diagnostic imaging standpoint. Aside from ultrasound, a digital radiography suite is going to be the most expensive upgrade for the private practitioner in the realm of diagnostic imaging.
