|Medical imaging is the method, procedure and art of producing visual pictures of the inside of a body for clinical examination and medical interference. Medical imaging seeks to reveal internal structures concealed by the skin and bones, as well as to analyze and treat disease. Medical imaging also creates a database of normal anatomy and physiology to make it imaginable to identify irregularities. Although imaging of removed organs and tissues can be performed for medical details, such measures are usually measured part of pathology instead of medical imaging.
High-impact journals are those considered to be highly influential in their respective fields. 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.
