both analog and digital imaging for several reasons. Show Maintain consistent signal intensity The first is to maintain a consistent signal intensity to the image receptor. This results in a consistent radiographic density in analog imaging. The outcome for digital imaging is consistent exposure indicators. The second reason we use technique charts in both analog and digital imaging is to maintain consistent radiographic contrast. The final reason that technique charts are important in both analog and digital imaging is that they balance image quality with patient dose. Technique charts are a vital factor in digital imaging because digital image receptors compensate for reasonable variations in exposure without visually changing density and contrast. Why is ALARA important in radiology?The ALARA radiation safety principle is important since it can help prevent both unnecessary exposure and overexposure to ionizing radiation. There are three cardinal principles that anyone who works with radiation sources should follow to help keep radiation doses “as low as reasonably achievable”.
What is the ALARA principle quizlet?As Low As Reasonably Achievable. ALARA principle. A principle that states that all radiation exposure to humans should be limited to levels that are as low as reasonably achievable.
How is the principle of ALARA applied in the diagnostic radiology environment?ALARA is an acronym used in radiation safety for “As Low As Reasonably Achievable.” The ALARA radiation safety principle is based on the minimization of radiation doses and limiting the release of radioactive materials into the environment by employing all “reasonable methods.” ALARA is not only a sound radiation ...
What are the three 3 principles of radiation protection for technologists?For reducing radiation exposure, there are 3 principals: time, distance, and shielding.
