Principles of X-ray Diffraction Diffraction effects are observed when electromagnetic radiation impinges on periodic structures with geometrical variations on the length scale of the wavelength of the radiation. The interatomic distances in crystals and molecules amount to 0.15–0.4 nm which correspond in the electromagnetic spectrum with the wavelength of x-rays having photon energies between 3 and 8 keV. Accordingly‚ phenomena like constructive and destructive interference should become observable

undergraduate research is incredibly important because studies show that the amount of hours spent working on research was directly proportional to the amount of perceived benefits of the research. Effort is so significant because it is so directly linked with the student perceived benefits. If the student is not putting forth much effort in the research project then it is safe to assume that the student does not see that there is any benefit in the research and therefore will most likely not benefit from

about patients with pacemakers and the new pacemaker technology out today that I would like to share. I have done a lot of research about this new pacemaker and I do feel that it is safe to use with an MRI‚ but with limitations. A pacemaker is a surgically implanted medical device that is installed to generate electrical impulses to treat irregular or stalled heart beats. If you were to put a patient with the old pacemaker in an MRI‚ there is a good chance the magnetic field of the MRI can interrupt

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

Dental X-ray Unit History Discovery of x-ray Professor Wilhelm Conrad Roentgen * 1895 discovered the first example ionizing radiation * the key to his discovery was device called a Crooke’s tube. Scientists and Researchers * Dr. Otto Walkhoff * the first to expose a prototype of a dental radiograph. * accomplished by covering a small‚ glass photographic plate with black paper to protect it from light and then wrapping it in a sheath of thin rubber to prevent moisture

How can small and medium- sized companies benefit from the use of business technology software? The purpose for the majority of the small and medium-sized companies is to improve their sales or growth. Nowadays‚ the online sales and the electronic data analysis represent a crucial phase to achieve this. Since a considerable number of years now‚ the use of software in the decision making by the large companies has been a regular practice. The competition this business faces is fearful‚ and the decisions

X-rays and Ultrasound: X-rays and ultrasound are two different modalities used for different things‚ so an ultrasound can do some things an X ray cannot‚ and vice versa‚ and so this makes them very difficult to directly compare. Ultrasound: Above: An ultrasound machine. Ultrasound is the use of energy generated by sound waves of 20‚000 or more vibrations per second. Ultrasounds are generated by a device called a transducer. Bearing in mind that sound is a mechanical energy‚ the transducer
