Final answer:
A helical scan performed on a 64 slice MDCT scanner is reconstructed with computer-enhanced cross-sectional X-ray images.
Step-by-step explanation:
A helical scan performed on a 64 slice MDCT scanner is reconstructed with computer-enhanced cross-sectional X-ray images. In computed tomography (CT), x-rays are passed through a narrow section (called a slice) of the patient's body over a range of directions. The relative absorption of the x-rays along different directions is computer analyzed to produce highly detailed images.
