Question

What 4 things should be checked on a wrist projection to ensure proper exposure factors were used?

Answer 1

To ensure proper exposure factors for a wrist projection, one should check the type and energy of the radiation, the particle or photon flux, and consider the chemical nature of the wrist which includes any irregularities. The outcome should always be cross-checked with standard exposure levels.

Step-by-step explanation:

When ensuring proper exposure factors for a wrist projection in radiography, the following four checks are necessary:

1. Type of radiation: Ensure that the type of radiation used is appropriate for the density and composition of the wrist, allowing for sufficient penetration without overexposure.
2. Energy of the particles: Verify that the energy levels of the individual particles or photons are set to produce a clear image without causing harm to the patient.
3. Particle flux: The number of particles or photons striking the area should be consistent with the needed dose for an optimal image.
4. Chemical nature of the wrist: Take into account any irregularities or variations in tissue composition that might affect the absorption of the radiation and, consequently, the quality of the image.

Additionally, when evaluating the radiographic outcome, always check that it makes sense and that the dosing is consistent with standard diagnostic exposure levels.
