The film vaguely shows the shape of the brain under the MRI image.


    This is DTI technology. Although Gao Baixiang is not a doctor in the Department of stem neurology, he knows something about it.


    Discrete tensor imaging (DTI), as the only new imaging technology that can show the movement of white matter fiber bundle in vivo, can check the integrity of corticospinal tract (CST).


    The application of this technology in brain research has only begun in recent years.


    About a year ago, Gao Baixiang''s circle of friends was brushed and marked with the most beautiful brain.


    The so-called most beautiful brain is nerve fiber bundle imaging. After a series of technical processing, the image data of the human brain is no longer only black and white, but a colorful form.


    Gao Baixiang has a deep memory of this. He watched many neurology professors and directors of Medical University sigh and wail in the group. He didn''t know when medical university could enter a similar machine so that they could operate it by themselves. He felt a little funny.


    This is the most cutting-edge medical technology in the world. If it is introduced in China, it will take 5-10 years?


    Unexpectedly, I saw this technology in jianxie hospital one year later.


    Mr. Wu is really at the forefront of technology. DTI technology is... Thinking that high white paper looks at Wu Mian squatting on the ground in an army posture through leaded glass. He is completely at a loss about what he is doing to the parts on the ground.


    Wei Dabao doesn''t understand DTI technology at all. The image is reflected in his eyes. The color is gorgeous, like a butterfly flying in the computer screen.


    "Director Gao, what''s this?" asked Wei Dabao somewhat confused.


    "It''s an MRI image of the head of a big white rabbit."


    "Is it an MRI?!" it is difficult for Wei Dabao to combine the black-and-white, monotonous and profound MRI images with these colorful dynamic images in front of him.


    "Well, you can say so." Gao Baixiang stopped paying attention to Wei Dabao and asked the technician, "Xiao Zou, what does Mr. Wu do? This is."


    "Mr. Wu wrote a software himself and put it into trial operation. As a result, the machine broke down in a few seconds." the technician said helplessly, "director Gao, I didn''t expect that the latest high-end machine signa architect 3.0T could crash."


    "Why collapse?" Gao Baixiang asked with good faith.


    "You look at the image..." as he said, the technician suddenly realized that he was too attentive when he just looked at the MRI. Gao Baixiang stood aside and quickly stood up and paid for it again and again. "Director Gao, I''m sorry, I''m too attentive. You sit down."


    "You sit down and say," Gao Baixiang pressed the technician''s shoulder and said with a smile, "tell me what''s going on."


    "Er... Miss Gao, how to explain this."


    "I don''t have any foundation. I do cycling. I seldom read NMR. You should explain it in detail as much as possible." Gao Baixiang understood what the technician meant.


    "People''s memory, vision, feeling and movement are stored in neurons in the cerebral cortex. Different nerve fiber bundles are connected in series or in parallel between different neurons, which are regulated by complex circuits such as the integration and analysis of thalamus and gray matter nuclei in the brain, so as to realize our arbitrary actions."


    "Look here."


    The technician said and clicked the key to stop the moving picture.


    "Here is the sensory nerve fiber bundle, here is the motor nerve fiber bundle. Under anesthesia, the activity of sensory and motor nerve fiber bundles is very poor, while the active is the memory nerve fiber bundle."


    "Rabbits also have memories?!"


    "Normally, there are." the technician scratched his head. "Hey, I don''t know. That''s what Mr. Wu said when I asked him just now."


    "Here are projection fibers, which connect the deep nuclei of the cerebral cortical nucleus with the brainstem, cerebellum and spinal cord, including afferent and efferent fibers. Typical representatives include corticospinal tract, cortical pontine tract, cortical medulla oblongata tract, visual radiation, etc."


    "Here are the connecting fibers, the fibers connecting part of the cortex of the ipsilateral hemisphere. They are divided into intracortical and subcortical connecting fibers, which are divided into short fibers and long fibers. In addition, they include buckle, upper and lower longitudinal bundles, hook bundles and upper and lower fronto occipital bundles."


    "Here are the commissural fibers, which connect the cortex of both cerebral hemispheres, including corpus callosum, anterior commissure and fornix."


    The technician pointed to the colorful patterns on the screen and said.


    "That''s all I know." the technician said with some embarrassment, "DTI technology is too new. Yesterday, Mr. Wu told me to learn it and gave me some information. After reading it all night, I just remember this."


    "Very good." Gao Baixiang patted the technician on the shoulder and said, "there is a problem with Mr. Wu''s software?"


    When he said this, Gao Baixiang was a little confused. Writing software, isn''t that what GE medical engineers should do?


    "I don''t think so." the technician shook his head. "It should be Mr. Wu''s requirements are too high. The operation load of GE''s signalarchitect 3.0T nuclear magnetic machine is too large, resulting in the machine shutdown."


    "Here, director Gao."


    Then the technician pointed to the image.


    "If there''s a problem with the program, there won''t be a moving picture for these seconds."


    "Originally, DTI data processing was to import the original scanning data into GE''s adw4.6 workstation, apply funetool software for post-processing, obtain ADC diagram and FA diagram, and reconstruct white matter fiber bundle diagram. But I don''t know why, Mr. Wu wrote a software himself, without GE''s adw4.6 workstation and funetool software."


    Gao Boxiang shook his head. Mr. Wu was not only good at medical treatment, but also understood engineering equipment. Gao Baixiang knew this when he couldn''t measure the value of blood oxygen saturation in Pengcheng.


    Now Mr. Wu even feels that the latest NMR can be disassembled and reassembled without Ge engineers at all.


    Gao Baixiang knows exactly what this means.


    Once the first DSA machine entered the second hospital of Medical University broke down and had to be repaired by the manufacturer. But there was no competition at that time. It belonged to the state of big store bullying. The manufacturer''s engineers didn''t fly until 22 days later.


    They took a look, changed a part, didn''t use 10 minutes before and after, and charged 250000 yuan.


    There are many similar things.


    Looking at Mr. Wu squatting on the ground and concentrating on playing with GE''s signa architect 3.0T nuclear magnetic machine, Gao Baixiang had mixed feelings.


    "Director Gao." Wu Mian shouted inside.


    "Ah!" Gao Boxiang hurried in.


    "It''s all right. You go back first and apply medicine to the patients with Takayasu arteritis. Regular medicine is OK. There''s nothing special. Don''t wait for me here, and so is Dr. Wei."


    "When are you going to get it?" Gao Boxiang asked.


    "Reassemble and try again. The software may have to be modified. I overestimate GE''s machine. It''s too detailed to run at all. If only it could be customized, it''s almost. If the problem was found before the crown prince came for surgery, I would directly ask for a ready-made one."


    "...." Gao Baixiang was speechless.


    I have crossed mountains and seas


    Wu Mian''s cell phone rang. He stood up and picked up the phone.


    "Boss Tao, rare guest, what are your instructions?" Wu Mian said and laughed casually.
