Which of the following will reduce the production of scatter radiation?

Which of the following grid errors will result in correct density in the center of the image, but lower density on the sides? Off-level Off-focus Off-center Upside-down

Remnant radiation consists of which of the following types of radiation? Absorbed Transmitted Scattered

A radiograph of a clavicle is taken using 12 mAs at 60 kVp with a 5:1 grid.  If an 8:1 grid is employed for the same exposure, what will the new mAs be?

Which of the following statements concerning grids are true? A grid cleans up scatter, which improves image contrast. The grid conversion factor is the amount of increase in kVp necessary when converting from nongrid to grid technique. A grid’s primary purpose is for radiation protection. A grid’s main function is to prevent Compton scatter from reaching the IR. Grids prevent the production of scatter.

Which of the following contrast agents are classified as radiopaque?

In a variable aperture collimator, which of the following structures are located immediately beneath the x-ray tube window?

Which of the following grid errors causes a loss of density across the entire image? Off-level Off-focus Off-center Upside-down

Which of the following set of technical factors will produce a radiograph with the least amount of contrast?

500 x-ray photons enter a patient and travel through 8 cm of tissue.  Approximately how many x-rays will exit the patient based on the tissue thickness?
