Question

the electromagnetic wave that ct scans are based on is called a
○ laser ablation.
○ positron emission.
○ sonograph.
○ x-ray.

Explanation:

• Laser ablation is a process using laser for material removal, not related to CT scan's electromagnetic wave.
• Positron emission is related to PET scans, not CT scans.
• Sonograph uses sound waves (ultrasound), not electromagnetic waves, for imaging.
• CT (Computed Tomography) scans use X - rays (a type of electromagnetic wave) to create cross - sectional images of the body.

Answer:

D. X - ray (assuming the options are labeled A - D as: A. laser ablation, B. positron emission, C. sonograph, D. X - ray)
