God-level academic master: My knowledge is the sum of all my students’ knowledge!

Huang Rui is a researcher at Huanyu Medical Devices Co., Ltd.

During his school career, he graduated from the Department of Biomedical Engineering of Huaqing University with the first place in the department.

Later, Huang Rui entered Johns Hopkins University to pursue a doctorate degree, conducting research in the fields of medical imaging, image processing and artificial intelligence.

In his working career, he has worked in top medical companies such as GE, Siemens, and Intuitive Surgical, and as a core staff member, he has developed a number of world-leading medical imaging products. In

April this year,

Huang Rui was hired with a high salary to serve as the director of the Photon Counting CT Laboratory of Huanyu Medical Devices Co., Ltd.

CT, or electronic computer tomography.

It uses precisely collimated X-beams, rays, ultrasound, etc., together with extremely sensitive detectors to perform cross-sectional scans around a certain part of the human body one after another. It has the characteristics of fast scanning time and clear images, and can be used to examine a variety of diseases.

Common CTs include ordinary CT, spiral CT, electron beam CT, and spectral CT.、PET-CT, etc.

Huang Rui’s research area is the more advanced photon counting dual-source CT.

Traditional CT requires two steps to convert X-rays into images.

Photon counting CT can directly convert X-ray photons into electric current to generate medical images.

In order to successfully develop photon counting CT, the detector on CT must be improved.

The detector is equivalent to the eyes of CT. After it obtains information, it reconstructs medical images through various mathematical and physical operations.

Since 1995, the material of the detector has always been scintillation crystals.

Huang Rui’s research and development route is to use semiconductor detectors made of cadmium telluride crystals.

In nature, cadmium telluride takes three million years to generate.

In the crystal laboratory of Huanyu Medical Equipment Co., Ltd., it only takes half a month to grow cadmium telluride crystals with a purity of 99.9999%.

After the successful development of semiconductor detectors, the progress of the entire scientific research project has been much faster.

However, in order to successfully develop photon counting CT, a large number of difficulties need to be overcome.

When he was at a loss,

Professor Chen Yu, chairman of the company, came to the laboratory and asked about the development progress of photon counting CT.

Faced with the chairman’s question,

Huang Rui naturally told the scientific research difficulties truthfully.

According to his idea, the chairman should encourage Team 28 and let all researchers keep up the good work.

Unexpectedly… the chairman stayed in the laboratory!

That’s right!

The extremely busy Chen chose to stay in the laboratory and work with the team to tackle the photon counting dual-source CT.

Of course, every profession has its own expertise.

Chen is not very good at mechanical engineering, electronic engineering, software engineering, quality system, and instrument design.

But he understands medicine!

He knows what medical equipment doctors need.

He knows what medical equipment patients need.

He understands the field of medical imaging diagnosis.

With the help of Chen, everyone worked together.

Mechanical engineers, electronic engineers, software engineers, quality system engineers, instrument designers and other team members worked together to successfully develop a photon counting CT prototype!

The performance of the prototype is very high.

The conversion efficiency of X has increased from 60 to 70 to more than 90.

The detector pixel has been reduced from a resolution of about 1 mm to 0.1 mm, becoming clearer.

Electronic noise is reduced, and radiation dose is reduced by more than 50%.

As for other advantages, they need to be discovered in clinical trials.

It is no exaggeration to say that the emergence of Universal Photon Counting CT is a milestone leap in the field of medical imaging diagnosis!

Next,

Huang Rui will contact the First Affiliated Hospital of Soochow University to conduct large-scale human clinical trials using the photon counting prototype.

If there is no problem with the clinical trial, then in the future, Universal Photon Counting Dual-Source CT will appear in major hospitals, thereby promoting the development of Xiaguo’s medical imaging industry.

In a real sense, it will benefit the vast number of Xiaguo patients.

……

On the other side.

In the company’s interventional robot laboratory.

A newly developed vascular interventional surgical robot is particularly eye-catching.

The robot consists of two units: bedside operation and surgical control.

The bedside operation unit is modularly designed and consists of a flexibly movable robotic arm and a disposable control box installed on the guardrail of the operating table.

The operation box is connected to the drive connector at the end of the robotic arm.

The power device in the box controls the guide catheter, guide wire, balloon or stent respectively, receives instructions to complete the push, pull and rotation movements, and the subtle movements can be accurate to 1mm compared to traditional vascular interventional robots.

The Huanyu vascular interventional surgical robot has the characteristics of reducing the radiation dose to doctors and patients during surgery, improving the accuracy of surgical control, reducing intraoperative contact between doctors and patients, small surgical trauma, fast recovery, and remote surgery.

Researcher Tan Liang looked at the device in front of him and sighed secretly.

The vascular interventional robot faces fragile human blood vessels and needs to operate interventional devices such as catheters, guide wires, and balloons. The product has high requirements on performance and stability.

Internationally, only Siemens’ Corpath surgical robot and European Robocath’s surgical robot can carry out coronary interventional surgery.

At present , no vascular interventional surgical robot has been approved in Xiaguo!

With the completion of the development of the Huanyu vascular interventional surgical robot, in the future, Xiaguo will have domestically produced vascular interventional surgical robots, which will be widely used in vascular interventional surgery to save tens of millions of patients with cardiovascular diseases.

Tan Liang was delighted and very grateful to Chairman Chen Yu.

During this period, Chairman Chen came to the interventional robot laboratory and asked him what help he needed.

In response to the chairman’s inquiry, Tan Liang truthfully told the scientific research difficulties he encountered.

After understanding the situation, Chen Yu used his medical knowledge to help Tan Liang solve the relevant scientific research difficulties.

In the end, the Huanyu vascular interventional surgical robot came into being!

Tan Liang was very grateful for this.

If it weren’t for Chairman Chen’s help, he didn’t know how long it would take to develop this device!

……

On the other side.

In the company’s MRI laboratory.

Zhang Tian looked at the newly developed medical equipment in front of him, and a smile rose from his lips.

MRI, or magnetic resonance imaging scanner.

It is a biological magnetic spin imaging technology that uses the characteristics of atomic nucleus spin motion to generate signals in an external magnetic field after radio frequency pulses. The signals are detected by detectors and input into the computer. After processing and conversion, three-dimensional detailed anatomical images can be displayed on the screen.

This equipment is usually used for disease detection, diagnosis, and treatment detection.

Intracerebral hematoma, extracerebral hematoma, brain tumor, intracranial aneurysm, syringomyelia, lumbar disc herniation and other diseases can be effectively diagnosed.

Ordinary tertiary hospitals generally use 1.5T magnetic resonance.

The scientific research field that Zhang Tian is engaged in is the more advanced 3.0T magnetic resonance.

The difference between the two is.

3.0T magnetic resonance has a higher magnetic field strength and higher resolution.

However… it is extremely difficult to develop a 3.0T magnetic resonance. Although domestic medical device manufacturers have independently developed 5T magnetic resonance.

But the key technology of 3.0T magnetic resonance has always been in the hands of foreign brands.

Let me give you a vivid example.

A 1.5T MRI is like a mid-range family car that anyone can drive.

A 3.0T MRI is like an F1 car that only a professionally trained driver can drive well.

The design and development problems in the field of magnetic resonance have always plagued domestic medical device manufacturers.

After Zhang Tian came to Huanyu Medical Devices Co., Ltd., he has always been committed to overcoming the difficulties in the field of magnetic resonance.

He faced four main problems.

First, MRI scanning has imaging noise.

To develop a magnetic resonance, it is necessary to reduce noise and improve the signal-to-noise ratio.

Second, to use higher field strength and more powerful radio frequency and gradient systems to obtain higher image clarity while providing faster scanning speeds.

The intensity of a 3.0T MRI is twice that of a 1.5T MRI.

How to use a faster scanning speed to obtain a clearer image is a great test of the manufacturer’s R&D capabilities.

Third, the high-intensity radio frequency excitation of a 3.0T MRI brings a higher SAR, which will bring danger to patients.

How to optimize the radio frequency hardware and sequence pulse design is a primary problem.

Fourth, how to ensure the imaging effect of optimizing fiber bundle tracking under ultra-high field DTI imaging, and how to enhance the accuracy of rapid imaging, is also a big problem.

Faced with various difficulties.

Zhang Tian was somewhat at a loss.

At this time, Chairman Professor Chen Yu came to his laboratory and asked what help he needed.

3.0T magnetic resonance imaging requires funds for research and development.

Mr. Chen immediately asked the finance department for funding! (To read the exciting novel, go to Faloo Novel Network!)

All aspects of the instrument related to medicine were tackled by Mr. Chen.

Finally, after arduous technical research.

The prototype of the Universal 3.0T MRI came into being! The equipment covers an area of 28 square meters, weighs 5 tons, has a scanning aperture of 70 cm, and a scanner length of 145 cm. Compared with the 3.0T magnetic resonance imaging on the market.

[]

Huanyu 3.0T MRI has 10 advantages.

First, the prototype can achieve sub-millimeter high-definition brain imaging.

This device can simultaneously stabilize the maximum gradient strength of 80 and the maximum gradient switching rate of 200.

The instrument is equipped with 64 dedicated coils for neurological function, which makes the signal-to-noise ratio and resolution of the image reach the extreme of 3.0T MRI.

It achieves sub-millimeter high-definition brain function imaging, accurately locates the functional area, can assist neurosurgery in setting up fine surgical plans, and can also avoid missed diagnosis and misdiagnosis of cortical lesions.

Second, the prototype can be installed in a large mobile trailer and moved from one place to another.

Third, the prototype can achieve 2mm clear diffusion imaging, can detect tiny lesions, and achieve early and accurate diagnosis.

Fourth, the prototype can carry out clinical diagnosis and research related to ultra-high B value.

Fifth, the prototype can observe the pathological state of thyroid nodules in a microscopic state.

Sixth, the prototype has free breathing enhanced imaging, and patients can complete the examination without holding their breath.

Seventh, the prototype can easily detect tiny liver lesions.

Eighth, the prototype can carry out cardiac MRI examination.

Ninth, the prototype can carry out cervical vascular plaque analysis.

Tenth, the prototype can perform high-definition joint imaging.

As for other advantages, they need to be discovered in clinical trials.

It is no exaggeration to say that the birth of the Universal 3.0T MRI is also a milestone leap in the field of medical imaging diagnosis!

……

On the other side.

Surgical robot laboratory.

Liu Shuai looked at the newly developed Huanyu surgical robot and clenched his fist excitedly.

The development of domestic surgical robots is a long way to go.

He faces four main research and development problems.

First, as a high-tech and high-precision medical device, surgical robots have extremely high technical requirements for manufacturing processes, key components, control systems, etc., involving knowledge in multiple disciplines, such as machinery, electronics, computers, and control.

Second, the development of surgical robots requires the support of mature robotics theory, advanced humanoid robot technology, and sophisticated mechanical devices.

Third, the development of surgical robots requires the most professional laboratories to conduct continuous experiments and test verification.

Fourth, the development of surgical robots requires a long period of large-scale capital investment.

Faced with various difficulties.

Liu Shuai struggled at first.

Fortunately, at this time.

Chairman Professor Chen Yu came to his laboratory and asked what help he needed?

Liu Shuai told him frankly.

Chen Yu didn’t understand technology, but he understood medical skills and could operate the world’s most advanced Da Vinci surgical robot.

He told Liu Shuai all his understanding of surgical robots.

After many instructions,

Liu Shuai was inspired.

Finally, he and his team successfully developed the Huanyu surgical robot!

The Huanyu surgical robot has”three heads and four arms” and its whole body is���Blue and white.

It consists of a surgeon’s console, a patient-side trolley, and a three-dimensional high-definition imaging system. 117

Compared with the da Vinci surgical robot.

The Huanyu surgical robot has eight advantages.

First, it has advanced intelligent image processing functions, and the ultra-clear 3D-HD imaging system magnifies the image ten times, making the image more high-definition and greatly improving the resolution ability.

Second, its robotic arms are smaller and lighter, with a wider range of motion, and can perform more complex and difficult surgical operations.

Third, it has a suspension device on the top of the head, which allows the robotic arms to rotate in a skirt group manner, freeing up valuable space for the surgical environment.

Fourth, it has a brand-new endoscope, which is simpler and more convenient to use and can save preoperative preparation time.

Fifth, when its robotic arms are positioned, laser positioning assistance is used, and intelligent and precise positioning allows doctors to more flexibly control surgical minimally invasive surgical instruments.

Sixth, its four robotic arms can rotate 720 degrees, which is 4 of the range of human hand movement and 3 times greater than the da Vinci robot.

Seventh, its four robotic arms can be used 20 times, more than 10 times of the da Vinci robot.

Eighth, as long as there is an optical cable, the operating table can be placed thousands of miles away to achieve remote surgery.

In general, the Huanyu surgical robot can easily perform complex cases of minimally invasive surgery and most tumor cases, covering various fields such as general surgery, urology, head and neck surgery, and gynecology.

……

At the same time, in the general manager’s office of

Huanyu Medical Device Co., Ltd. , Dong Xin is checking the latest development progress of the company’s medical devices. The development progress shows that Huanyu’s 3.0T MRI prototype has been successfully developed! Huanyu’s surgical robot has been successfully developed! Huanyu’s photon counting dual-source CT prototype has been successfully developed! Huanyu’s vascular interventional surgery robot prototype has been successfully developed!

……

Dong Xin looked at the densely packed research and development progress reports and couldn’t help but smile.

If it continues to develop at this pace, it won’t take a few years.

Universal Medical Devices Co., Ltd. will become the world’s top medical device company!

Of course…

Dong Xin knew very well.

The reason why the company’s scientific research progress is so fast is, on the one hand, the powerful scientific research team, and on the other hand, the repeated guidance of Director Chen.

Director Chen’s attainments in various medical branches such as medical imaging, vascular intervention, and surgical operations have already reached a superb level.

His advice is even more useful than a month of hard work by scientific researchers!
