The emergence of electronic computers, to the fine diagnosis of the gospel. CT is a member of the family of medical instruments in the newcomer, medically known as the tomography device. CT scanning can be a part of the body into a number of different depths of the image, and then use electronic computers to make these images into a 1-mm-square single cube, which consists of a cube of data. Electronic computers based on these data on the screen to clearly show this part of the main body map, any point of the lesion can not escape, people say CT is the doctor's "God's eye".
CT is not only widely used in medical diagnosis, in modern archaeology also shows the magic effect. Ancient Egyptian mummy is one of the ancient wonders, is the ancient Egyptians using a special process made of dried and not rotting body. The production method is very fine, first from the left side of the deceased opened, in addition to the heart to take out all the internal organs, and then cleaned with spices, in the abdominal cavity filled with palm oil, onions, cedar wood chips, sand, wood shavings, etc., with sodium carbonate will be ascites suction, with rosin-like resin coated with the whole body, with linen will be the limbs and the entire torso layer after layer of wrapping securely immersed in the rosin, take out and dry, and finally put into the special humanoid coffins.
To study the mummy, we have to open the burlap, the mummy anatomy, which is bound to destroy the mummy. Is there any other way not to destroy the mummy? The University of Illinois World Heritage Museum to change the practice of dissecting mummies, mummies to do CT. once, a Chicago antique dealer sent a mummy, asked for research, but not allowed to destroy the mummy. Prof. Wiseman accepted this difficult research project. In profile, the mummy was 140 centimeters long, with a pair of large eyes on a flat face, and a golden laurel-ringed crown faintly visible on the forehead. Nothing is known about the mummy's age, chronology, gender or cause of death.
Wiseman first examined the mummy with X-rays, which showed the growth of the bones but did not find the amulet, leading to the conclusion that he must have been a poor child. Then the mummy for CT scanning, scanning images not only clearly to the skeleton, shroud, rosin, etc. revealed, the abdominal cavity of the tissue is also clear at a glance. After analysis, the age of the deceased for eight or nine years old, from the method of linen wrapping and painted decorations can be seen, about 2,000 years ago. The back of the body was also found from the scanned images, and there was a wooden board bent in line with the body shape from head to toe, indicating that the body was made when it began to decompose, and the board was used to support the body. A headshot of the deceased was also recovered through the CT scan.
An archaeology at the Museum of Fine Arts in Boston, Massachusetts, is even more exciting. Archaeologist Myron Marks used a high-resolution CT scanner. Marks chose a high-definition CT scanner to study a mummy. From the tablets unearthed with the mummy, Marks knew that the mummy was Tabitha, a famous songstress in ancient Egypt 3,000 years ago. Her family lived in a small town called Zebes in the Nile Valley and her husband was a barber. She died in 930 BC at the age of 30. How did Tabes die? What did she look like then? These are two fascinating questions. Marks took 271 photos of the mummy with a CT, which were repeatedly compared by an electronic computer to make up a three-dimensional image that reproduced all of Tiberius' bones, muscles, eye sockets, hair and internal organs.
The Egyptian archaeologist was amazed at the computerized image. He praised it, saying, "Its clarity is so high that it is like Tiberius regenerated." The scientist who had seen the depicted image gave a description of the singer Tiberius: "She looked like a flower in life, with bright eyes and deep eye sockets; she had a mouth full of jade-like teeth without a single carious hole; her hair was shoulder-length, and her skin was fair and elastic; she was moderately shaped, like a celestial fairy." From the images shown on the CT, there was a trap within the parietal bone of her skull, which could determine that Tabes died of a brain tumor.
The introduction of CT machines has led to great advances in both medicine and archaeology. The computer has given doctors a pair of "eyes" and archaeologists a pair of hands that can retrieve the past.
