Introduction

Introduction

In 1895 Wilhelm Conrad Roentgen was experimenting with light when he unexpectedly discovered a new form of electromagnetic energy that he called X rays. Roentgen found that the rays could penetrate a person's hand, and the outline of bones could be seen on a chemically coated fluorescent screen behind the hand. Roentgen then replaced the screen with photographic film to make lasting pictures of the images. Radiography studies are being replaced by digital (computerized) examinations. Today, x-ray studies are often performed as the initial examination to diagnose a wide variety of diseases and injuries that is beneficial in the medical industry today.

This research seeks to provide information on the uses of x-rays in radiotherapy and imaging. It seeks to provide a well informative research on what is radiotherapy, the applications of x-rays, the uses of x-ray in radiotherapy and imaging.

The Use of X-ray in Imaging

Wilhelm Conrad Roentgen found that the rays could penetrate a person's hand, and the outline of bones could be seen on a chemically coated fluorescent screen behind the hand. Roentgen then replaced the screen with photographic film to make lasting pictures of the images. Today X-ray film, or radiography, studies are being replaced by digital (computerized) examinations, which may be viewed either as film or on a video screen. These improved techniques and machines have minimized radiation doses and thus potential radiation injury due to exposure from X rays. These machines include the CAT scan, MRI, Ultrasound, PECT and SPECT.

Computerized Axial Tomography

CT scan is an advanced system for medical X-ray imaging of the interior of the body. In X-ray technology tomography refers to a method for obtaining sectional views of the body that eliminate X-ray shadows of body structures before and behind the desired section. The term axial indicates a series of cross-sectional X-ray images made along a chosen body axis, and the term computerized indicates that the series of images is then combined into a single three-dimensional image by means of a computer. CAT-scan images provide much more detailed information than ordinary X-ray pictures.

    What is Spectroscopy?

    4 star(s)

    Spectroscopy started in 1666 when Sir Isaac Newton passed rays of light from the sun through a glass prism and observed the colours of the visible spectrum, another great breakthrough concerning spectroscopy was the suggestion of transition between energy levels within atoms as the source of spectral lines was great contribution made by Niels Bohr in 1913.

    Physics is the study of matters, forces, energy and interactions between objects. According to Wikipedia (2005), physics discovered the applications of natural sciences. Physics is also called "The Fundamental Science", because other sciences (biology, chemistry etc.) have to obey the law of physics.

  1. Are mobile phones harmful to our health

    "This biased appraisal of the science should be viewed cautiously by the general public." Professor Mike Repacholi, co-coordinator of the WHO electromagnetic fields project 1996-2006, said there was no scientific basis to a link between "electromagnetic hypersensitivity" - where symptoms include burning sensation on the skin and fatigue - and exposure to EMF.

  2. Ultraviolet radiation and skin cancer

    Bohr's Model is analogous to what happens when UVB radiation falls on the organic sunfilters. UVB photons have a wavelength range of 280-315nm and we can calculate their range of frequencies by using the formula : Range = = 1.1 x 1015 Hz to 9.5 x 1014 Hz.

  1. Should radioactive smoke alarms be a compulsory purchase?

    Conclusion Having considered two different types of smoke alarm I would say that BOTH types of smoke alarm should be made a compulsory purchase for UK homes. This is because, after looking at the tables, I have found that the average number of fatalities per 1000 fires is 3.2 where a fire alarm is present and working.
