What imaging technique uses computer synthesis of X-rays through a specific plane of the body?

The correct answer is Computed Tomography (CT), which is an imaging technique that utilizes a series of X-ray images taken from different angles around a specific plane of the body. These images are then processed through computer algorithms to create cross-sectional images, known as slices, of the body's internal structures. This allows for a detailed view of organs, tissues, and even bones, providing valuable diagnostic information that can greatly aid in medical assessments.

CT scans are particularly valuable because they offer more detailed images than traditional X-rays, making them useful in various clinical situations, such as detecting tumors, internal injuries, or other abnormalities. The precision and speed of this technique make it a vital tool in medical imaging.

Other options, such as ultrasound and MRI, utilize different principles. Ultrasound uses high-frequency sound waves to create images and is often used for soft tissue imaging without radiation exposure. MRI employs strong magnetic fields and radio waves to generate detailed images of organs and tissues, also without the use of ionizing radiation. An electrocardiogram (ECG) focuses on electrical activity in the heart rather than providing images of anatomical structures. Each of these modalities has its own specific uses, but CT's unique combination of X-ray technology and computerized synthesis is what distinguishes it
