Line compensator- measures the voltage provided to the x-ray imaging system and adjust that voltage to precisely 220 V. input voltage can vary up to 5%. b. Autotransformer- is designed to supply precise voltage to the primary side of high voltage transformer and to the filament circuit. c. kVp controls- by selecting the major or minor kVp controls‚ a more precise kilovolt peak is provided. kVp

relatively straightforward. A beam of light from a visible and/or UV light source (colored red) is separated into its component wavelengths by a prism or diffraction grating. Each monochromatic (single wavelength) beam in turn is split into two equal intensity beams by a half-mirrored device. One beam‚ the sample beam (colored magenta)‚ passes through a small transparent container (cuvette) containing a solution of the compound being studied in a transparent solvent. The other beam‚ the reference (colored

Microscope Microscopes are instruments that produce a magnified image of a small object. They are used in many scientific and industrial applications. Some common applications for microscopes include manufacturing inspection and high-technology quality control. Specific quality control applications for microscopes include semiconductor processing‚ medical imaging‚ cell research‚ and metallurgical analysis. Microscopes are supplied in one of three common configurations‚ student‚ benchtop‚ and research

December 12 2013 Radioisotopes are used in the branch of nuclear medicine to convey information on the operation of a person’s organs‚ or to treat specific diseases. Most of the time‚ radioisotopes are used by physicians and other scientists such as chemists‚ to make a quick and precise diagnoses of the patient’s illness. The bones‚ heart‚ and thyroid can easily be viewed or imaged with the use of radioisotopes in medicine. Additionally‚ in some cases radioisotopes can be used to treat diseased

different .ways‚ at different magnifications/ In a transmission electron microscope‚ the electron beam passes through a very thin prepared sample. The electrons pass through the denser parts of the sample less easily‚ which gives some contrast. The final image produced from a TEM is two-dimensional. The magnification possible with a TEM is times 500‚000. With a Scanning electron microscope‚ the electron beam is directed onto a sample and unlike the TEM‚ the electrons do not pass through the specimen
