Radiologic Technologist Practice Exam

Which of the following is NOT considered during the establishment of technique charts?

1. radiographer skill

2. patient age

3. casts

4. contrast media

The correct answer is: radiographer skill

The establishment of technique charts involves considering various factors that influence the quality and outcome of radiographic imaging. Radiographer skill, while essential to the performance of imaging procedures, does not directly play a role in the technical parameters defined on a technique chart. Technique charts are developed based on consistent factors that affect imaging, such as patient age, which impacts tissue thickness and density, necessitating adjustments in exposure settings. The presence of casts is also considered, as they alter the attenuation of X-rays and require changes in the technique to ensure proper visualization of underlying structures. Contrast media plays a crucial role, as different contrast agents can affect the required exposure due to their differing densities. Therefore, while the technical skills of a radiographer influence how effectively they can execute a given technique, they are not explicitly addressed in the creation of technique charts, which focus on mechanical and physiological factors.
