Medical Imaging 1895, when Wilhelm Conrad Roentgen accidentally used a one night during X-ray was born in the search. Little did he know that one of her biggest, the discovery of one of the party, not a medical tool. For over one hundred years, scientists, physicists and other medical imaging technology to improve picture quality has progressed, increasing the speed of the process and reduce the amount of radiation exposure. During this time a lot, used for recording images as content is changed. However, still many things are similar, for example, how to shoot. Now comes the biggest change of all - the film is no longer necessary because the medical imaging combines digital age.

Each time, share or make a nuclear radiation is different from their parties.The same effect occurs in a nuclear explosion, but the X-ray energy is a minor source, strongly reduced the intensity of radiation. X-rays are a form of radiation. When passing through a material, X-rays are partially absorbed in the direction of transmission. Radiation to destroy or alter the molecular structure of living cells are capable of. X-ray body serious damage, skin burns, nausea, inflammation and cancer, reactions, and may cause. However, X-rays to destroy cancer cells even when used in radiotherapy.

It was found that X-ray radiation burns and cancer researchers to develop many early after the damage caused to human tissue. More than 100 people including the wife of dangerous Roentgen X-ray, died after contact. Late 1950 and early 1940, the shoe X-ray units, adjusting the shoe store, a conversion of a joint promotion. Shoe fit the X-ray unit was assigned to 1950, recognized the dangers of radiation machines and radiation leaks into the environment on the agenda were often used for optimization. In 1970, the shoe-fitting x-ray units had been banned in 33 states, and the remaining 17 states were in a strict regulation of their practical operation.

Once the X-ray effects were known, doctors new to the X-ray found ways to reduce the harmful effects. Time is the key, because time is directly proportional to the dose rate. Methods were developed to do the same, if not better quality, while reducing the amount of exposure time. Very long exposure times in the past, one or more extreme for mammography in minutes, and dose rate. A high level of radiation X-ray can benefit ...
