Transcript of THE X-RAY

The X-Ray was discovered in the year 1895 by a man named Wihelm Roentgen. this discovery created an amazing step foward in the history of medicine.
What is the x ray you ask, well its a technological invention that allows us humans to look into the body without cutting flesh.
Brief history of the X-RAY
Wihelm Roentgen was a physics professor in Worzburg, Bavaria. Roentgen was exploring the path of electrical rays passing from an induction coil through a partially evacuated glass tube. He was the first person to discover the possibility of using electromagnetic radiation to create what we all know as the X-Ray.
Benefits and Consequences
When the imaging properties of x-rays were discovered, their practical use for research and diagnostics was immediately apparent, and soon their use spread in the medical field. X-rays were used to diagnose bone fractures, heart disease, and phthisis. Inventive procedures for different diagnostic purposes were created, such as filling digestive cavities with bismuth, which allowed them to be seen through tissue and bone.
catch on time
Around march of 1896 the fluoroscope that thomas edison developed became the standard for medical X-ray.
The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England on 11 January 1896, when he radiographed a needle stuck in the hand of an associate.[72] On 14 February 1896 Hall-Edwards was also the first to use X-rays in a surgical operation
Radioactive materials that decay spontaneously produce ionizing radiation, which has sufficient energy to strip away electrons from atoms (creating two charged ions) or to break some chemical bonds. Any living tissue in the human body can be damaged by ionizing radiation in a unique manner. The body attempts to repair the damage, but sometimes the damage is of a nature that cannot be repaired or it is too severe or widespread to be repaired. Also mistakes made in the natural repair process can lead to cancerous cells. The most common forms of ionizing radiation are alpha and beta particles, or gamma and X-rays.

Before the X-ray
Injuires were being diagnosed by physical examination, or doctors best guess. in 1897, a year after its first clinical use, the x-ray was being used in diagnosis and therapy.
