What is a Tomogram X-ray?
What is X-ray Computed Tomography (CT) X-ray Computed Tomography (CT) is a nondestructive technique for visualizing interior features within solid objects, and for obtaining digital information on their 3-D geometries and properties. 3D reconstruction of skull of Herrerasaurus, with cutaway showing brain case.
What is micro XRF analysis?
Micro X-Ray Fluorescence (Micro-XRF) analysis is an accurate, rapid, cost effective, test method for elemental surface analysis. Micro XRF provides fast screening and detection of trace elements, with advanced non-destructive elemental analysis.
Which instrument can be used to study the penetrating ability of X rays?
X-ray microscope
An X-ray microscope uses electromagnetic radiation in the soft X-ray band to produce magnified images of objects. Since X-rays penetrate most objects, there is no need to specially prepare them for X-ray microscopy observations.
What do xrays consist of?
An X-ray is a packet of electromagnetic energy (photon) that originate from the electron cloud of an atom. This is generally caused by energy changes in an electron, which moves from a higher energy level to a lower one, causing the excess energy to be released.
What can be examined on a Tomogram?
It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels. CT scans are more detailed than standard X-rays.
What is the difference between Edxrf and Wdxrf?
The main difference between ED and WDXRF is in the achievable spectral resolution. WDXRF systems can provide resolutions between 5 and 20 eV, whereas EDXRF systems provide resolutions between 150 to 300 eV or more, depending on the variety of detector used.
What is Micro XRD?
Micro X-ray diffraction analysis (µXRD) is a structural analysis technique which allows for the examination of very small sample areas. Like conventional XRD instrumentation, µXRD relies on the dual wave/particle nature of X-rays to obtain information about the structure of crystalline materials.
Why would a doctor order a full body scan?
Full body scans are medical imaging procedures that will tell you what is going on in your entire body, from the brain to the toes. It could help to catch dangerous diseases like cancer in the early stages when it is still curable.
What is the difference between a CT scan and a CAT scan?
So, CAT and CT scans both mean the same type of diagnostic examination. CAT was used earlier in its history, while CT is the recent up-to-date term for convenience sake. The term CT stands for computed tomography and the term CAT stands for computed axial tomography or computerized axial tomography scan.
What can be examined on a tomogram?
What is Wdxrf used for?
X-ray fluorescence (XRF) spectrometry is a non-destructive analytical technique used to obtain elemental information from different types of materials.
What elements can Wdxrf detect?
The range of detectable elements varies according to instrument configuration and set up, but typically EDXRF covers all elements from sodium (Na) to uranium (U), whilst WDXRF can extend this down to beryllium (Be). Concentrations can range from 100% down to ppm and in some cases sub-ppm levels.
What is alpha beta and gamma rays?
Gamma rays are neutral, while alpha particles have a positive charge and beta particles have a negative charge. Two protons and two neutrons are bound together to form an alpha particle. High-energy electrons are known as beta particles. Gamma rays are photons, which are electromagnetic energy waves.
