What does Computed Tomography (CT) use to create images of the body?

1. X-rays and computer processing

2. Magnetic fields and radio waves

3. Ultrasound waves and sound frequencies

4. Optical imaging techniques

The correct answer is: X-rays and computer processing

Computed Tomography (CT) utilizes X-rays in conjunction with computer processing to generate detailed cross-sectional images of the body. This technique involves taking multiple X-ray images from various angles, which are then processed by a computer to produce comprehensive images that can show both the structure and any potential abnormalities within the body's tissues. The use of X-rays allows for capturing a wide range of data, and the computer processing is crucial for reconstructing this data into a coherent visual representation. The other methods listed, such as magnetic fields and radio waves or ultrasound waves, pertain to different imaging technologies like Magnetic Resonance Imaging (MRI) and ultrasound imaging, respectively. Optical imaging techniques involve visual observation or capturing images through light capturing methods, which are distinct from the X-ray technology that CT employs. Thus, the combination of X-rays and sophisticated computer processing is what distinctly defines the CT imaging technique.
