Question

CT scan

a) Magnetic and radio waves are directed through the body to produce a picture of a specific location in the body.
b) A type of x-ray that is directed through the body at different angles to produce a picture of a "slice" or cross-section of the body.
c) A camera is attached to a fiber-optic tube passed through the nose, throat, larynx, and trachea and into the lungs creating pictures of the respiratory system.
d) A picture of a specific location in the body is produced by having the patient swallow radioactive iodine and measuring the locations of radioactive output.

Answer 1

A CT scan, or computed tomography, is a noninvasive medical imaging technique that uses x-rays to produce highly-detailed images of specific locations in the body. It involves passing x-rays through the body and using detectors to capture the x-rays. Complex computer image processing is used to create detailed images that can be analyzed and used to produce three-dimensional information.

Step-by-step explanation:

A CT scan, also known as computed tomography, is a noninvasive medical imaging technique used to produce highly-detailed images of specific locations in the body. It involves passing x-rays through a narrow section of the body over a range of directions. An array of detectors on the other side of the patient registers the x-rays, and complex image processing produces a detailed image. Different slices are taken as the patient moves through the scanner, and multiple images can be computer analyzed to produce three-dimensional information.
