Everyday we use technology as a common tool. Even now we are using technology to view this. But did you know that there are various technologies, that help us scientist understand the internal body system. These technologies allows us to understand what is going inside our bodies. Based on all that we know right now we could foresee what the future of technology holds. Eg. Replacing major organs and curing cancer.
Before insulin, diabetes was a really bad diseases. It would have been a 100% death if you had diabetes. In October 1920 in Toronto, Canada, Dr. Frederick Banting, had an idea that the juice created in the pancreas could be harmful. He told his to the leading figure of study in diabetes, Professor John Macleod. He gave Banting a Lab and ten dogs. He also gave him Charles Best his assistant. They discovered insulin by crushing th dog's pancreas and mixing it with water.
In January 1922 a small 14 year old boy who was dieing from diabetes was the first person to receive the insulin. The 14 year old boy, Leonard Thompson quickly regained his strength and appetite. Banting and Best quickly delivered the insulin to volunteer and charities.
Another great invention would be the invention of X-rays. The invention of X-rays was discovered by a German Physicist named W.C.Roentgen. He discovered X-rays by working with tubes similar to our fluorescent light bulbs. the tube would create a fluorescent flow and found that the light could go through solid object. He named the ray, X-ray, because in mathematics "X" is the unknown quantity. X-rays could be harmful because it was shown that it could cause cancer and skin diseases.
The third important invention would be the Cat Scans. Cat scanning also called CT scanning use special x-ray equipment to produce multiple images of the inside of a body. CT scanning is one of the fastest ways for studying the chest, abdomen and pelvis, because it provides detailed, of all types of tissue. It helps diagnose many different cancers, including lung, liver and pancreatic cancer. CT scan was discovered by a British engineer named Sir Godfrey Hounsfield and Dr. Alan Cormack.

MRI's are also a medical imaging technique used to visualize detailed internal structures. MRI provided many colors showing different soft tissue of the body. It is useful for imagain the brain , muscles, and the heart. The MRI was first developed by Dr. Raymond Damadian, a physician and scientist, that wanted to scan a body using magnets. He volunteered to be the first patient. When he climbed in nothing happened. One of his colleagues suggested that he might be too big for the machine. A graduate student then volunteered to do it. On July 3, 1977, the first MRI scan was performed on a human being. It took five hours to produce one image.
