Chapter 8: Medical Imaging Equipment 1. Which component of the x-ray tube produces the x-rays? A. Cathode B. Anode C. Glass envelope D. Collimator Answer: B Rationale: The anode (B) is the component of the x-ray tube where electrons from the cathode strike, producing x-rays through the process of bremsstrahlung and characteristic interactions. DIF: Knowledge TOP: X-ray Tube Components MSC: Radiographic Equipment 2. The primary function of the cathode in the x-ray tube is to: A. Pro...

Motion blurMotion blur - 1. Movement of the patient or the x-ray tube during exposure results in blurring of the radiographic image. This loss of radiographic quality, called motion blur, may result in repeated radiographs and therefore should be avoided. 2. Patient motion is usually caused by motion blur. Suspend respiration for exposures, decrease exposure time, use a large SID and use a small OID. Transverse - across the table, at right angles to longitudinal. Longitudinal - along th...
