US developed a new CT scan that is faster and faster
Release date: 2006-08-17 U.S. develops a new CT scan that is faster and faster. The United States has developed a new CT scan that is faster and faster. According to an article in Applied Physics News, scientists at the University of North Carolina recently developed a carbon fiber X-ray. A new approach to creating new computed tomography (CT) images that scan faster and use lower peak power than previous CTs.
The meaning of the Yellow River Beach Jujube is that the long dates on the edge of the Yellow River, called jujube in the locals, commonly known as "beach dates", scientific name "wood dates." Beach Jujube growth in the distance from the Yellow River within 50 meters to 1500 meters on the beach, elegant environment, fresh air, adequate sunshine, large temperature difference between day and night, is the essence of Mother River nourishing and breeding, characterized by huge particles, was Cylindrical, color, such as Mexican jade, soft sweet fruit pulp, known as "ginseng fruit."
Beach jujube large nuclear, thin flesh, crisp long, juicy sweet, sweet mellow, high sugar content, bright red color, less water, long shelf life, good quality. Really is "sweet and smelly stone sweet partial Yong, red Ma Zhu cherry color Mo", is the color, smell, taste, shape jujube. Yellow River Beach jujube nutrition is very rich. Jujube is rich in protein, fat, sugar, carotene, B vitamins, vitamin C, vitamin P and phosphorus, calcium, iron and other ingredients, of which the highest content of vitamin C among the fruits, the "Vitamin C" reputation. Eat the Yellow River beach jujube can cure the weak, neurasthenia, stomach and indigestion, indigestion, labor and cough, anemia and other diseases.

It is understood that the currently applied CT scanner is slow and has a low effect. Carbon nanotubes are composed of a layer of carbon atoms and have a diameter as small as 1 nanometer. Researchers using carbon nanotubes in this study are based on their ability to emit electrons without heating.
Conventional CT scanners use mechanical means or rotate an X-ray source or rotate a scanned object while X-ray imaging at approximately 1000 different angles. As early as 2005, the researchers developed a multi-X-ray source scanner that does not require mechanical rotation, but quickly switches between X-ray sources. Each of the light sources gets a different angle of image during rapid alternation. The latest innovation is the combination of this multi-X-ray source and multi-channel technology. All X-ray sources are illuminated at the same time, and images at various angles are obtained.
In this study, the researchers used a prototype of their multi-channel scanner to scan an electrical computer board, and then compared the results with traditional X-ray scanners. The results were clear and clear. The difference is slightly different, but the prototype device scans faster.
The researchers said their next research goal is to develop a real small CT scanner to scan small animals. (Shanghai Medical Device Network)
