Sleepless Doctor

Latest URL: The film can vaguely see the shape of the brain under the NMR image.

This is DTI technology. Although Gao Boxiang is not a doctor in the Department of Neurology, he knows a little bit about it.

Scattered tensor imaging is called DTI for short, as the only new imaging technology that can show the course of white matter fiber bundles in vivo, it can check the integrity of the corticospinal tract (CST).

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

About 1 year ago, Gao Baixiang's circle of friends was screened and labeled-the most beautiful brain.

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

Gao Boxiang remembered this deeply. He watched the many neurology professors and directors of the Medical University sighing and wailing in the group. He didn't know when the Medical University could enter a similar machine so that they could also operate it by themselves. He felt a little funny.

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

Unexpectedly, I saw this technology in Jianxie Hospital a year later.

Teacher Wu is really at the forefront of technology. DTI technology is... thinking, through the leaded glass, he watched Wu Mian squatting on the ground in a military posture, and he was concentrating on what he was doing on the parts. At a loss.

Wei Dabao doesn't understand DTI technology at all. The image is mapped in his eyes, the colors are bright and colorful, like a butterfly flying in the computer screen.

"Director Gao, what is this?" Wei Dabao asked in confusion.

"It's an NMR image of the head of a white rabbit used in the experiment."

"It's NMR?!" It is difficult for Wei Dabao to combine the black and white, monotonous and profound NMR image with these colorful dynamic images in front of him.

"Well, you can say that." Gao Boxiang stopped talking to Wei Dabao and asked the technician: "Xiao Zou, what is Mr. Wu doing?"

"Ms. Wu wrote a software by himself and tested it after inputting it. As a result, the machine crashed after running for a few seconds." The technician said helplessly, "Director Gao, I didn't expect the latest high-end machine like SIGNA Architect 3.0T to crash. "

"Why did it collapse?" Gao Boxiang asked Xiner.

"You look at the image..." As he said, the technician suddenly realized that he was too attentive when looking at the MRI. He stood Gao Boxiang on his side, and quickly stood up, repeatedly making no mistakes, "Director Gao, I'm sorry, I Look too attentively, sit down and sit down."

"Sit and say." Gao Boxiang pressed the technician's shoulders and said with a smile, "Tell me what's going on."

"Uh... Teacher Gao, how do you explain this."

"I don't have any foundation, I do circulatory work. I rarely read NMR. You can explain it in detail as much as possible." Gao Boxiang understood what the technician meant.

"Human memory, vision, sensation, movement, etc. are all stored in neurons in the cerebral cortex. There are different nerve fiber bundles between different neurons to connect them in series or in parallel, plus the thalamus and gray matter nuclei in the brain. The integration and analysis of complex loop adjustments, so as to achieve our arbitrary actions."

"Look here."

The technician said, clicked the button, and the animation stopped.

"This is the sensory nerve fiber bundle, and this is the motor nerve fiber bundle. Under anesthesia, the sensory and motor nerve fiber bundles have poor activity, while the memory nerve fiber bundle is active."

"Bunny also has memories?!"

"Normally yes." The technician scratched his head, "Hey, I don't know. The teacher Wu I asked just now, he said so."

"Here is the projection fiber. It is the fiber connecting the deep brain nucleus of the cerebral cortex nucleus with the brainstem, cerebellum, and spinal cord, including afferent and efferent fibers. Typical representatives are the corticospinal tract, cortical pontine tract, cortical medulla oblongata tract, and optic fiber. Radiation etc."

"Here is the connection fiber, it is the fiber that connects the cortex of the ipsilateral hemisphere. It is divided into intracortical and subcortical connection fibers. The latter is divided into short fibers and long fibers. In addition, it includes buckle, upper and lower longitudinal bundles, hook bundles, and upper and lower cortex. Forehead occipital bundle."

"Here is the joint fiber, the fiber connecting the cortex of the cerebral hemispheres on both sides, including the corpus callosum, the anterior joint, and the fornix joint."

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

"I know this." The technician said embarrassedly, "DTI technology is too new. Yesterday, Teacher Wu told me that I should learn it and gave me some information. After watching it all night, I remembered this."

"Very good." Gao Boxiang patted the technician on the shoulder and said, "Ms. Wu has a problem with the software?"

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

"I can't see it." The technician shook his head. "It should be that Mr. Wu's requirements are too high. GE's SIGNA Architect 3.0T nuclear magnetic machine is overloaded, causing the machine to stop."

"Here, Director Gao."

As he said, the technician pointed to the image.

"If there is a problem with the program, there will be no animation for these few seconds."

"Originally, the DTI data processing was to import the original scan data into GE's ADW4.6 workstation, apply FuneTool software for post-processing, obtain the ADC map and FA map, and reconstruct the white matter fiber bundle map. But I don’t know why, Mr. Wu wrote it himself A piece of software, useless GE's ADW4.6 workstation and FuneTool software."

Gao Boxiang shook his head. Teacher Wu is not only good at medical treatment, but also understands engineering equipment. This point, Gao Boxiang understood the time when the blood oxygen saturation clip could not be measured in Pengcheng.

Now Mr. Wu can even disassemble and reassemble the latest NMR, without using GE engineers.

What this means, Gao Boxiang knows too well.

The first DSA machine entered in the Second Hospital of Medical University once broke down and can only be repaired by the manufacturer. But there was no competition at that time, and the store was bullying customers. The manufacturer’s engineers flew over after 22 days.

They took a look and changed a part. It was useless for 10 minutes and charged RMB 250,000.

There are many similar things.

Seeing Mr. Wu squatting on the ground concentrating on playing with GE's SIGNA Architect 3.0T nuclear magnetic machine, Gao Baixiang had mixed feelings in his heart.

"Director Gao~www.wuxiaspot.com~ Wu Mian shouted inside.

"Eh!" Gao Boxiang walked in quickly.

"It's okay, you go back first, and give medicine to patients with aortic arteritis. Regular medicine will do, nothing special. Don't wait for me here, and Doctor Wei too."

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

"Reassemble and try again. The software may need to be modified. I overestimated the GE machine. It was too detailed and couldn't run. If it could be customized, it would be fine. It would be better if it was discovered before the crown prince came to perform the operation. The question, just ask for a ready-made one."

"..." Gao Boxiang was speechless.

[I used to cross the mountains and the sea...]

Wu Mian's cell phone rang, and he stood up and picked up the phone to connect.

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