How are ct images produced
Web8 de ago. de 2024 · CT images are two-dimensional pictures that represent three-dimensional physical objects. The images are made by converting electrical energy (moving electrons) into X-ray photons, passing the photons through an object, and then converting the measured photons back into electrons. WebX-rays are similar to gamma rays however the main difference is the way they are produced, ... It is this penetrating power that allows us to take internal images of the human body or objects. X-rays cannot be steered by electric and magnetic fields like alphas, betas or other charged particles. ... including about 1.1 mSv from CT scans.
