Answer: D
Radiography Physics
- What is a rigid holder that contains the screens and film?
- What is used to test for screen contact?
- Term used to describe the noisy appearance of an image that has been exposed by a limited number of X-ray photons?
- What is the predominant cause of image Noise?
- True or False - When the Energy of the photon approaches the energy of the K-shell electron, the absorption of the beam increases this is called the K edge.
- What is a disadvantage of rare earth screens?
- Intensifying screens use phosphors that emit light by "blank"?
- When it comes to Fluorescence, there is a process similar to characteristic X-ray emission, but involves outer shell electrons, this is called "blank blank" theory?
- Which of the following is NOT a Rare earth phosphor?
- True or False - There are two intensifying one in front, and one in the back of the film.
- What is the air gap technique normally used for?
- Most chiropractic work will be in the range of (blank) to (blank) for xrays?
- What is the most common type of grid?
- If you use a grid what happens to your contrast of the film?
- True or False - The radiographic contrast approximately doubles by using a grid?
- What is the Bucky factor when it comes to the Grid?
- What is the primary transmission when it comes to the Grid?
- What is the most common type of Grid cut off?
- Which of the following is NOT a reason for Grid Cutoff?
- True or False - Most grids are unfocused.
- What is the most common type of Grid?
- True or False - If you decrease the X-ray beam field size the amount of tissue exposed regardless of thickness or density scatter radiation can be diminished?
- What is the most common type of shape distortion?
- As the Object film distance increases the detail (blank)?
