Final answer:
In radiologic technology, Rad techs control the use of an X-ray tube, which involves adjusting settings such as current, potential difference, exposure time, and beam angle to obtain quality diagnostic images and ensure patient safety.
Step-by-step explanation:
The content loaded question appears to be related to the field of radiologic technology (Rad tech). In this context, the 'Rad tech controls the use/above of the tube' seems to be asking about the control of an X-ray tube. Radiologic technologists, or Rad Techs, are responsible for the operation of X-ray machines, which are used to capture images of the inside of the body for diagnostic purposes. The technologist can control several aspects of the X-ray tube, including the current (milliamperes, mA) or the potential difference (kilovolts, kV), the duration of exposure, and the angle of the beam relative to the patient, among other settings. These settings are critical because they directly affect the quality of the image produced and the dose of radiation the patient receives. It is very important for the rad tech to properly set and use the X-ray tube to ensure diagnostic quality images while minimizing radiation exposure to the patient and adhering to radiation safety principles.
