When using a radiographic grid with computed radiography (CR),
A)the Moire effect is a consideration.
B)higher frequency grids are undesirable.
C)radiographic grids are unnecessary.
D)none of the above

Question

Quizplus · Accepted Answer

When using a radiographic grid with computed radiography (CR), the Moire effect can occur, which is an undesirable interference pattern. Therefore, it is a consideration when choosing and using a radiographic grid. Choice B is incorrect, as higher-frequency grids are generally more effective at reducing scatter radiation, but the choice of grid frequency depends on the specific imaging situation. Choice C is incorrect, as radiographic grids are often necessary to reduce scatter radiation and improve image quality, especially for larger body parts.
