Grids

Device used to reduce the amount of scatter radiation reaching the film, enhancing image contrast and detail. Grids consist of a series of alternating lead strips and radiolucent material, allowing primary radiation to pass while absorbing scatter, which helps in achieving a clearer image.

Technique Charts

Guides used in radiography to determine appropriate settings (kVp and mAs) based on part thickness, patient size, and specific examination types. Technique charts are essential for ensuring optimal image quality while minimizing patient exposure to radiation.

mAs

Controls the number of electrons passing from cathode to anode in the x-ray tube
