How does a CT scan achieve its detailed images?

A CT scan achieves its detailed images by taking multiple cross-sectional X-ray images and reconstructing them. The process involves rotating the X-ray tube around the patient, capturing several images from different angles. These images are then processed using advanced algorithms to create a detailed cross-sectional view of the body. This method not only enhances the visualization of internal structures but also allows for the differentiation of various tissues based on their density, providing clinicians with critical information for diagnosis and treatment planning.

The other imaging modalities mentioned, such as the use of magnetic fields, real-time movement observation, and infrared imaging techniques, do not apply to the process of CT scanning. Magnetic resonance imaging (MRI) utilizes magnetic fields, while modalities like ultrasound visualize real-time movement, and infrared imaging is typically for surface temperature measurement, neither of which contribute to the detailed imaging achieved through CT technology.
