X-ray Computed Tomography (CT) - Techniques

WebThe X-ray source is generally referred to as either the ‘anode’ or the ‘cathode.’ Both of these terms are in fact inaccurate. The source of X-rays is the cathode ray tube. As ‘cathode ray’ is an outdated term and the tube contains both a cathode and an anode the correct term would appear to be simply X-ray tube, or X-ray source. 1 WebIn x-ray imaging the x-rays are emitted from the anode of the x-ray tube. The x-rays all come out from there in what is called a divergent geometry. The primary x-rays all travel in straight lines from the x-ray tube to the detector. software-rechteWebHere is a detailed breakdown of the process: An x-ray beam with enough energy to impact the electrons in the inner shells of the atoms in a sample is created by an x-ray tube inside the handheld analyzer. The x-ray beam is then emitted from the front end of the handheld XRF analyzer. The x-ray beam then interacts with the atoms in the sample by ... software recommendations stack exchange
