There is a reduction of scattered radiation reaching the output phosphor of the image
intensifier


The image becomes brighter

,Term 3 of 147
Which of the following describe the correct usage of the "boost" position or high level control in
fluoroscopy?


i. Increases the tube current and potential above normal limits
