1. What is a CT scanner?
A CT scanner (abbreviated as a CT scanner, or also known as a CT scan) is a modern diagnostic imaging device that uses X-rays to penetrate soft tissues inside the body to reproduce images from the resulting projections.
With the support of computer algorithms, the CT scanner CT scan will create each image layer clearly, detailed and sharp thanks to extremely high contrast.
Also uses X-rays like thechup X-ray machine, however, it is called computerized CT scan because the detector system to emit X-rays has increased the number of rows to obtain more tomographic images and is thinner, combined with computer imaging software to create many clear image slices. Currently, CT scanners have the number of slices from 2, 4, 8, 16, 32, 64 to 128, 256 and 512.
Depending on each manufacturer, CT scanners of each brand will have different scanning speeds and slice thicknesses, along with imaging software that will produce different image quality, specifically:
