Technologies makes us able to see some internal parts of the human body.
It was the year 1895 when Wilhelm Roentgen discovered the X-rays, since then picturing the bones inside the body became possible.This X-rays passes trough the soft parts of the human body and stop by the bones and teeth. Through this, the doctors and specialist could see broken bones and even tooth cavities inside.
Later in 1970’s, a new kind of X-ray machine was developed, it is called a CAT scanner. With the CAT scanner, X-ray pictures are taken from many angles then a computer combines the X-ray pictures into a single picture on a computer screen.
Precautions should also be considered as much exposure to the X-rays can be harmful to patients.
With the advent of new technology, a new way to see inside the body was also developed. This is called the “nuclear magnetic resonance”, or NMR.
The NMR machine is using a huge magnet and radio waves. Information from this radio waves will be taken by the computer. The computer then generates picture or images. The NMR works better than X-rays when it comes comes in taking pictures of soft body tissues, but still the X-ray takes better pictures on bones.
The NMR was said to have no harm to patients.
