[ RadSafe ] Medical Radiological Technician Oversight

[John Jacobus]

It is called the switch.  

Seriously, except for the very rare mechanical failure
of the equipment, exposure parameters are usually well
defined to produce the appropriate image.  Of course,
I assume you are refering to diagnostic imaging.  In
many cases, the equipment has automatic exposure
control (ACE) devices to monitor the radiation passing
through the receptor.  The ACEs will cut back on the
voltage or amperage, or both, to ensure the proper
image.  

There is no benefit in giving the patient too much
radiation, as there is no benefit in giving too little
radiation.
