Computed Tomography

All x-ray imaging is based on the absorption of x rays as they pass through the different parts of a patients body. Depending on the amount absorbed in a tissue such as muscle a different amount of x rays will pass through and exit the body. The amount of x rays absorbed contributes to the radiation dose to the patient. During conventional x-ray imaging, the exiting x rays interact with a detection device and provide a 2-dimensional projection image of the tissues within the patient's body - an x-ray produced photograph called a "radiograph. CT scans exposes you to more radiation than regular x-rays. Having many CT scans over time may increase your risk for cancer. The risk from any one scan is small. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
