BDA Radiography and Radiology
Questions and Answers 100% Pass
What is the function of the focusing cup in the X-ray tube?
✔✔ To direct the electron beam toward the anode.
What is the significance of using a vacuum in the X-ray tube?
✔✔ To ensure efficient electron flow and prevent interference from air molecules.
What is a contrast agent?
✔✔ A substance used to enhance the visibility of specific structures in radiographic imaging.
What is the role of the anode in the X-ray tube?
✔✔ To serve as the target for electrons, producing X-rays.
What does "image receptor" refer to in radiography?
✔✔ The device that captures and stores the X-ray image.

,What is the purpose of immobilization devices during radiographic procedures?
✔✔ To minimize patient movement and improve image clarity.
What is the main purpose of radiography?
✔✔ To produce images of internal structures for diagnosis and treatment.
What does the term "radiology" refer to?
✔✔ The medical specialty that uses imaging to diagnose and treat diseases.
What is a radiograph?
✔✔ An image produced by X-rays passing through a patient and captured on a detector or film.
What is the primary component of the X-ray tube that generates X-rays?
✔✔ The anode.
What is the role of the cathode in the X-ray tube?
✔✔ To produce and emit electrons for X-ray production.
2
, What is the significance of kVp in radiographic imaging?
✔✔ It controls the energy and penetration ability of the X-ray beam.
What is the purpose of mAs in radiographic settings?
✔✔ It controls the quantity of X-rays produced during exposure.
What is scatter radiation?
✔✔ Radiation that deflects in different directions after interacting with matter.
What is the function of a collimator in radiographic equipment?
✔✔ To limit the size of the X-ray beam to reduce exposure and improve image quality.
What is the purpose of a grid in radiography?
✔✔ To reduce scatter radiation and improve image contrast.
What does radiographic contrast represent?
✔✔ The difference in densities between different parts of the image.
