a. Plain radiography, also known as X-ray radiography, is used to visualize bones and some soft tissues but does not provide real-time moving images like fluoroscopy.

c. Mammography is a specialized type of X-ray imaging used for breast examination, primarily for detecting breast cancer.

d. Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create detailed images of organs and tissues, but it does not use X-rays for imaging.

A. Using sound waves to create images of internal structures. B. Utilizing magnetic fields to visualize bones and soft tissues. C. Utilizing ionizing radiation to penetrate tissues and create images. D. Emitting radio waves to visualize organs and blood vessels.

Correct Answer is D

Explanation

X-ray imaging uses ionizing radiation, which has high energy and can penetrate tissues. When X-rays pass through the body, they are absorbed differently by various tissues, creating an image that allows visualization of bones and soft tissues.

a. Using sound waves to create images of internal structures refers to ultrasound imaging, not X-ray imaging.

b. Utilizing magnetic fields to visualize bones and soft tissues describes magnetic resonance imaging (MRI), not X-ray imaging.

d. Emitting radio waves to visualize organs and blood vessels is a principle of MRI and not X-ray imaging.
