1. From the beginning of the question to the medical image
Under normal circumstances, organs and tissues in the human body cannot be seen with the naked eye. In ancient times, famous doctors such as Bianque and Huaying diagnosed the internal causes of patients by "looking, smelling, asking, and cutting". This is the most "advanced" diagnosis of that era.
One day in 1816, French doctor Reneck walked down the street, accidentally seeing a few children hitting one end of a piece of wood with a big nail, while the other children used their ears to stick to the other end of the wood. To listen to the sound, this gave Dr. Reneck a great inspiration. When he got home, he immediately found someone to make a hollow wood tube, which was the first stethoscope in human history. Later, the stethoscope was widely used in the heart and obstetrics.

In modern times, doctors observe the condition of the patient's body and no longer just use a stethoscope to solve it. In 1971, the formal establishment marks the advent of CT medical imaging, along with advances in medical imaging technology, evolved from the Department of Radiology Department of Radiology, clinical medicine to become the fastest growing disciplines, from traditional X-ray extension To ultrasound, radionuclide imaging, X-CT, MRI, digital imaging, and today's most advanced PET-CT technology. With these new technologies, doctors are able to "snoop" the lesions inside the body more deeply.
2. Fusion master of image data - PACS system
The emergence of medical imaging equipment has made medical clinics increasingly rely on medical imaging inspections. Traditional medical image management methods (films, pictures, and materials) are accumulated over the years, stored and kept year after year, and pile up mountains, which brings many difficulties to find and read. The loss of movies and materials occurs in hospitals. The traditional method of document management has been unable to meet the management requirements for such large and large-scale medical images in modern hospitals.
With the development of database technology and computer communication technology, digital image transmission and electronic film came into being. Many hospitals have carried out hospital information reforms. With the gradual update of imaging equipment to digitalization and the maturity of the Internet, filmless radiology and digital hospitals have become a reality. Regarding electronic film, we will introduce it in detail in the next article. I will not elaborate on it for the time being.
In order to uniformly store and manage the informationized data of different medical imaging equipments, the PACS system, the master of data integration of each platform, was born.
The English translation of the PACS system is the meaning of the image archiving and communication system. Its main task is to pass various medical images (including nuclear magnetic, CT, ultrasonic, various X-ray machines, various infrared instruments, microscopes, etc.) to various interfaces (analog, DICOM, The network) is stored in a digital way. When doctors need them, they are quickly transferred back to use as a housekeeper, perfectly acting as a lubricant between instruments.

Double Packed Yellow Waxy Corn Cob
The most common waxy and sweet corn market, waxy corn nutrient content is higher than ordinary corn, contains 70-75% starch (and almost all amylose), more than 10% protein, 4-5% fat and 2% multivitamin, has more grain, VA, VB1, VB2 than rice protein, fat and VB2 highest content. Yellow corn also contains carotenoids like rice and wheat. The molecular weight of glutinous corn starch is more than 10 times smaller than that of ordinary corn. The starch makes glutinous rice sticky and soft, which is softer than that of ordinary hard corn. It has more than 20 percent more digestibility than regular corn and is suitable for people with irregular teeth. At the same time, the amylose (a polysaccharide) content is very high, not suitable for diabetics.
Waxy corn is also called sticky corn. The grain has a coarse, waxy endosperm that resembles a glossy, transparent grain, such as a hard, dented corn. Its chemical and physical properties are controlled by a recessive gene located on chromosome 9. 100% of the starch in the endosperm is amylose.
