Question Answer
Added filtrationLimiting the x-ray beam by the use of a piece of aluminum or aluminum equivalent outside the glass window of the housing
Aperature DiaphragmA piece of flat lead with a hole in the center that attaches to the x-ray tube to confine the area of the beam
Beam limitation deviceEquipment that reduces the beam to only those areas in need of exposure
ConesA circular metal structure attached to the x-ray tube housing to restrict the x-ray beam to a predetermined size
Cumulative timing deviceA device that presets the on time for the tube to only five minute increments
Flat contact shieldRubberized lead strips that are placed over areas of the body to protect them from exposure
Gonald ShieldingProtection of the reproductive organs from radiation exposure
Half Value Layer (HVL)The thickness of the material which will reduce the x-ray intensity to half of its original value
Image intensification FluroscopyA procedure used to increase the brightness of an image with a decreased exposure time
Inherent filtrationLimiting the x-ray beam by use of a glass window in the tube and cooling oil surrounding the tube housing
Intensifying screenA device that serves to accelerate the action of x-rays by converting x-ray energy into visible light
Intermittent FluoroscopyProcedure of periodically activating the fluoro tube rather than continuous exposure
