Ohio GXMO Study Guide Review, Gxmo
Ohio review info Questions and Answers
What does filtration do? Removes low energy x-ray photons from the x-ray beam that
cause unnecessary patient expsoure
Radiation scatter production is increased when? The collimator is wide open, the kVp is
too high, or the body part is to thick
Quality of the beam is? kVp
The focal spot size may effect the? Sharpness of the image
What would you increase by 15% to double image density? kVp
What is the primary factor to control image contrast? kVp
Increasing the SID will result in? A lower patient dose
,What is the overall "blackness" of the image? Density
What has the greatest radiographic density? Detail
What represents the lowest mAs setting? Density
The low mAs setting used with high speed intensifying screens can result in quantum
mottle
What is the radiosensitive material that receives the remnant beam and forms an image of the
body part? Image Receptor
What is the invisible image contained in film prior to processing? Latent image
Fluroscopy is? The moving x-ray and pt swallows barium sulfate
, The purpose of intensifying screens is to reduce or decrease the amount of? Exposure
required to produce an image
When using intensifying scrreens, what percent of the image is actually formed by light?
99%.
Higher speed screens are made of? Thicker phosphor layer and an increase of crystal size
Pairing a green light emitting screen phosphor with a film sensative to green light is?
Spectral Matching
What is an artifact? Unwanted marks or images appearing on an x-ray
Using a higher screen speed and decreased mAs will result in Increased quantum mottle
What is the purpose of the film cassette? Prevent light from exposing the film, prevent
marks from scratching and bending the film, provide support for intensifying screens
