Siheyuan: Rebirth in a prosperous era, great doctors are sincere

Chapter 594: Prisoners still want to find a job?

CT, or computed tomography, is a medical imaging technology.

It uses X-ray beams to perform tomographic scans of the human body and uses computer processing to produce detailed images of the body's internal structures.

CT scanning is widely used in the diagnosis of various diseases due to its fast and clear imaging capabilities.

CT was invented by an electrical engineer in the United States in the early 1960s, patented and mass-produced in the 1970s.

In fact.

Li Pingan knew that China had the ability to produce CT at that time.

When Manager Liu of Modou Medical Equipment came to Beijing again and contacted Li Pingan, Li Pingan told him about his desire to develop CT.

Manager Liu came to investigate the use of B-ultrasound, PCR amplifiers and other medical equipment in various hospitals in Beijing. Li Pingan took the opportunity to tell him about his idea of ​​having the Magic City Medical Equipment Manufacturing Plant develop a CT.

Li Pingan is very clear about the imaging principles of CT.

The patient lies on the CT scanner bed and the X-ray emitter rotates around the patient's body.

X-rays are a type of high-energy electromagnetic radiation that can penetrate human tissue.

As X-rays pass through a patient's body, different tissues absorb them to different degrees due to their density and thickness. For example, bone absorbs more than soft tissue, and air absorbs very little.

Opposite the X-ray emitter, there is a row of devices called detectors that record the remaining intensity of the X-rays that pass through the patient's body.

When the X-rays pass through the patient's body and are received by the detector, the data is sent to the computer for processing. The computer converts the received signals into digital signals for storage.

The computer processes the received data using reconstruction algorithms (such as filtering and back-projection algorithms) to restore a cross-sectional image of the human body.

The reconstruction algorithm generates an image by calculating the absorption of X-rays in different directions.

Finally, computer-generated cross-sectional images can be viewed on a monitor, allowing doctors to detect lesions, assess tissue structure, and make diagnoses.

X-ray examination uses X-rays to capture images by passing through the different densities of human tissue; while CT examination uses computer reconstruction technology to process X-ray images at different angles to obtain slice images.

CT scans generally have a higher resolution than X-rays. CT scans can provide high-resolution three-dimensional images, making it easier to identify and detect lesions.

X-rays are often used to detect broken bones, lung infections, intestinal obstructions, etc. CT scans can be used for a wider range of conditions, including detecting head injuries, adrenal gland problems, swollen lymph nodes, etc.

CT has a wider range of uses and is more practical than X-ray examinations, especially in neurosurgery. CT plays a much greater role than X-ray examinations. If CT can be manufactured, it will be more convenient for doctors to perform brain surgery, the possibility of accidents will be smaller, and there will be fewer postoperative side effects.

After the Sixth Hospital established the Department of Neurosurgery, Li Ping'an focused his attention on the development of CT.

After repeated research, he believes that China currently has the ability to develop CT and the manufacturing process is not complicated.

Manager Liu agreed with Li Ping'an's opinion.

After developing B-ultrasound and PCR amplifiers, China has acquired the ability to develop CT.

Li Pingan has explained the principle of CT very clearly, and Manager Liu believes that the Magic City Medical Equipment Factory has the ability to develop it.

Even if they alone can't do it, they can definitely succeed by joining forces with a few other electronics and computer research institutes.

When Chu Shan was researching PCR amplifiers in the past, he was responsible for contacting multiple units for collaboration. Manager Liu suggested that this time it would be best to let Chu Shan be in charge of the on-site scheduling and contact the various units involved in the development of CT.

Li Pingan agreed.

He went to the medical university laboratory with Manager Liu.

After learning the purpose of the two people's visit, Li Pingan introduced the imaging principle of CT. Chu Shan said excitedly: "Pingan, I think this machine you call CT is not complicated to develop, and it may be successful soon!"

CT is a development of the X-ray machine, but almost all technical problems have been overcome, so it should not be difficult to develop it.

Manager Liu also agreed with this view and said: "If everything goes well, the research will be successful within two or three months, and the equipment can be mass-produced within half a year at the latest!"

Chu Shan was very excited and said at the time that after he finished some work in the laboratory, he would prepare to develop CT with Manager Liu.

If CT can be developed, both neurosurgery and other departments will have a powerful assistant, which will be of great help to the domestic medical industry.

Several people chatted happily.

Manager Liu immediately expressed his intention to treat Li Pingan and Chu Shan to a meal.

Several people went to a restaurant near the Medical University Hospital together.

Manager Liu is in Beijing on a business trip.

He brought a lot of money, national food coupons, and even meat coupons.

He ordered three bowls of noodles and some meat dishes.

The three of them talked while eating.

Li Pingan further explained to the two the various technologies required in CT manufacturing.

While they were talking, Xu Xiang came over with a disheveled man.

Looking at the sumptuous dishes on the table, Xu Xiang's eyes showed a subtle anger, but she quickly suppressed it, and said with a fake smile: "Chu Shan, are you guys eating?"

Chu Shan's face looked a little grim.

His gaze paused on the somewhat sloppy man, and he just nodded slightly without saying much.

Xu Xiang continued to smile and asked: "Chu Shan, please introduce them to me. Who are these two..."

Manager Liu was sitting in the middle holding a briefcase. It was obvious that he was sitting in the main seat as he was the one who was going to treat everyone.

Xu Xiang felt that Manager Liu was no ordinary person and wanted to meet him.

Chu Shan briefly introduced both parties.

Only then did Li Ping'an realize that the disheveled man was actually Xu Xiang's husband and Liu Qi's father.

This guy has been released from prison.

It turned out to be Li Pingan and Manager Liu from the Modou Medical Equipment Factory.

Xu Xiang's heart moved and said: "What are you talking about? Is there any important experiment to be done? Can Lao Liu and I also participate in it? Chu Shan knows our strength, there is no problem!"

indeed.

Liu Huaigong was released.

However, neither the original laboratory, medical university, medical university hospital, etc. accepted him.

It's been a few months.

Chu Shan still hasn't found a good job.

He used to be a professor at a medical university and a laboratory leader, but now he can't even find a job.

Neither the Medical University Hospital wants it.

Other hospitals with equal or even better strength will not accept it.

Liu Huaigong didn't want to lower himself to work in a small hospital, and gradually became an unemployed vagrant.

even.

Now he is too lazy to even take care of his appearance.

Love is what it is.

This time, when Xu Xiang took her husband to the restaurant for dinner, she unexpectedly met Chu Shan and others. She thought this was a great opportunity.

The experiment that Chu Shan and Li Pingan have to complete together is definitely not a small experiment, it may be a big project.

If the two women specifically asked their husband Liu Huaigong to participate, he might be able to return to the laboratory and even take back the leadership of the laboratory.

Chu Shan and Manager Liu both focused their attention on Li Pingan.

It was he who proposed the development of CT, so he was of course the backbone of the project.

If Li Ping'an explained the situation and asked Liu Huaigong and his wife or even Liu Qi to participate, they would not say anything.

Xu Xiang and Liu Huaigong also noticed the attitudes of Chu Shan and the other man, and turned their attention to Li Pingan.

Li Pingan said: "We are just chatting. Manager Liu is here to investigate the use of PCR amplification instruments in various hospitals and laboratories. Professor Chu and I must cooperate with him!"

Xu Xiang's face looked a little grim.

Li Ping'an answered her question, but it was the same as if he hadn't said anything.

This is a very official answer.

Even if Manager Liu didn't tell her the purpose of his visit, she could find someone to find out, but Li Ping'an didn't mention whether he had any other specific purposes.

Liu Huaigong's face darkened.

She had heard everything about the PCR amplifier from her wife. Chu Shan had made great efforts in the development process and had also received great honor.

then.

He and Chu Shan had similar status in the medical university, but now he and Chu Shan were not comparable at all.

In the field of biochemistry, especially in genetic research, Chu Shan became a leading figure, while he was doing so miserably that he even lost his job.

The notoriety of having been to prison will probably follow him for the rest of his life. How easy will it be for him to enter the laboratory and conduct research again?

Even thinking about being an ordinary doctor in a hospital is probably difficult.

Xu Xiang also knew that she couldn't force him, but she still smiled and said, "Li Ping'an, our son is Liu Qi, he is your colleague. Your Uncle Liu is in trouble now and may not be able to go back to the laboratory of the Medical University to work. Can you help transfer us to your Sixth Hospital? Our family of three are all doctors and can help in the laboratory. Liu Qi's wife Zhou Ling is a nurse. We can all help the development of the Sixth Hospital. Please consider it. Your Uncle Liu's medical skills and achievements in scientific research are very high, and his ability is not much different from Chu Shan's!"

Doesn’t Li Ping’an know why Liu Huaigong went to jail?

Does Xu Xiang still dare to brag that her husband is on par with Chu Shan?

Can Li Pingan believe it?

He sneered and said, "Since you are about the same level as Uncle Chu, just stay in the Medical University. Our Sixth Academy is too small to accommodate a big Buddha like him!"

Li Pingan refused at that time.

How could he not know what kind of people Liu Huaigong's family were?

From the very beginning, Liu Huaigong and his wife sent their son Liu Qi to the Sixth Hospital in order to compete with Li Ping'an for credit, but in the end they got nothing.

Xu Xiang's smile froze instantly, and she cursed Li Ping'an and Chu Shan countless times in her heart.

She turned to look at Chu Shan and said, "We are colleagues, please help us speak up for us!"

Chu Shan was a little embarrassed.

Since Liu Huaigong was released from prison, Xu Xiang has looked for him countless times, asking him to help Liu Huaigong ask his superiors to accept her husband.

pity.

Chu Shan is a person who turns a deaf ear to the outside world and stays in the laboratory wholeheartedly. He has rejected Xu Xiang many times.

This time Xu Xiang asked for help from himself again.

He was not in a position to refuse, but also did not want to speak for Liu Huaigong. After a moment's silence, he finally said, "Don't make it difficult for me. Ping An has his own considerations. The Sixth Hospital, the Sixth Hospital Laboratory, and the Medical School are all thriving under his management. I can't interfere and affect the development of the Sixth Hospital and other units!"

Xu Xiang's eyes once again revealed hatred, but this expression was also fleeting. She turned her gaze to Manager Liu and said, "You are Manager Liu of the Magic City Medical Device Manufacturing Factory, right? My husband Liu Huaigong is really an amazing biochemist. He can do what Chu Shan and Li Pingan can do. If your factory needs a biochemist, can you let my husband join in? He will definitely work hard!"
