X Ray

What are X-rays? X-rays are a form of radiation that can pass through solid and semi-solid substances. In carefully controlled doses, they can be used to capture images of the body's internal structures. How X-rays work X-rays are a type of radiation. Light and X-rays are similar sources of energy. However, light has a much lower frequency than X-rays and is absorbed by your skin. X-rays have a higher frequency and pass through the human body. As X-rays pass through the body, energy particles...

Main Components Of An X-Ray Rays Case Study

components of an X-ray Tube? The x-ray tube consists of an electrode pair - a cathode and an anode. The cathode is a negatively charged heated filament made from tungsten. The anode is a positively charged flat disc, also made from tungsten. The electrode pair sits inside a glass vacuum tube, which is lined with lead for protection. 2) State the two interactions that occur in the X-ray tube to produce the x-ray beam Bermsstralhung interaction and Characteristic interaction. 3) The X-ray beam is attenuated...

Mammography: X-ray and Breast Tissue

with higher resolution, faster, lower-dose screen-film combinations, have contributed to earlier cancer detection in women. Dr. Wilhelm Conrad Roentgen discovered x-rays while working with a Crookes tube in his laboratory on November 8, 1895. Eighteen years later mammography got its rudimentary beginnings due to these ionizing x-rays. In 1913, Berlin Albert Soloman, a German surgeon, was among the first to discover that breast cancer could be radiographed. In a 1927 medical textbook the first instance...

Comparison of X-Ray and Ultrasound

X rays and Ultrasound are two of the main imaging techniques used in radiography. For the purposes of this essay, we will look at conventional x-rays and diagnostic ultrasound. Conventional x rays are non-invasive diagnostic techniques that are used to capture images of the body's organs and bones. Diagnostic ultrasounds are high frequency sound waves to create an image of soft issues in the body such as muscles, joints, and internal organs. As examined below, while both are used in diagnostic radiography...

X-Ray Absorption Spectroscopy

X-ray Absorption Spectroscopy X-ray absorption spectroscopy (XAS) techniques probe short- and medium-range order, yielding information on bond lengths, coordination numbers, local coordination geometry and the oxidation state of atoms for a wide range of solid and liquid systems. XAS experiments require an intense, tunable photon source only available at synchrotrons. Features • medium and high energy (from atomic number Z=20 upwards) XAS, XANES (x-ray absorption near-edge structure)...

X-ray Powder Diffraction Analysis: Principles, Instrumentation and Applications

X-ray Powder Diffraction Analysis: Principles, Instrumentation and Applications M.S.Pandian Department of Earth Sciences, Pondicherry University, Puducherry-605014 Introduction X-ray powder diffraction analysis (XRD) is perhaps the most widely used X-ray based analytical techniques for characterizing materials. As the name suggests, the sample is usually in a powdery form, consisting of fine grains of crystalline material to be studied. The term 'powder' really means that the crytalline domains...
