The Fundamentals of CT Scans
CT scans, also called computed tomography scans, use X-rays to create detailed, three-dimensional photos of inner constructions. These photos are obtained by transmitting X-rays by way of the physique and detecting how a lot of the X-ray sign is absorbed or blocked by totally different tissues and supplies.
How CT Scans Work
CT scans use a rotating fan-shaped X-ray beam to seize detailed photos of inner constructions. The X-ray beam is transmitted by way of the physique, and a detector on the opposite aspect measures the depth of the X-ray beam after passing by way of the physique. The detector sends the information to a pc, which reconstructs the X-ray photos into detailed cross-sectional photos.CT scans use a method referred to as “attenuation” to calculate the quantity of X-ray power absorbed by totally different tissues and supplies.
The X-ray beam is transmitted by way of the physique in skinny slices, that are then reconstructed right into a 3D picture utilizing subtle pc algorithms. This course of permits docs to visualise inner constructions, corresponding to organs, blood vessels, and bones, in nice element.
