Chapter 726: Converting And Reconstructing The Data
Translator: EndlessFantasy Translation Editor: EndlessFantasy Translation
“Huh?” Chief Chen was stunned for a moment.
Zheng Ren held the patient’s CT radiographic films in his hands as countless thoughts flew through his mind.
In the ruins of Nanchuan Town, the life-and-death surgery had allowed him to touch upon the great fetters of technology. However, he had also unintentionally broken these fetters.
Although it was only reflected in the surgery then, Zheng Ren knew that his ability to read radiographic films would definitely provide a leap in his abilities.
When he was performing surgery at Pengxi Village Hospital, more relevant information would involuntarily appear in his mind every time he saw the patient’s radiographic films.
If it were not for the fact that he was at the frontline and countless patients were waiting for treatment, Zheng Ren would have long been unable to suppress his curiosity to ponder about it.
At this moment, facing a patient with abdominal pain, the radiographic films that Zheng Ren saw and the fragments that appeared in his mind were not the same.
The CT radiographic films were simplified and turned into data. Then, they were fused in his mind and turned into what Zheng Ren wanted.
Because Zheng Ren could already see the patient’s diagnosis, the burden of merging and completing the data was not big. He immediately found the anomaly in the radiographic films, locating the problem.
Looking at the radiographic films in front of him, there was only a very vague anomaly. If one did not look carefully, this would just seem like any ordinary CT film of a retroperitoneal hematoma. The abnormality could be misdiagnosed as a fatty deposit or a false shadow.
However, it was a different scene when Zheng Ren looked at the radiographic films now.
Su Yun came over, frowned, and asked, “Boss, I think these radiographic films are fine.”
Chief Chen also felt like it was strange but did not say anything. His experience in Nanchuan Town made him realize that this young doctor was special. Otherwise, he wouldn’t have specially called Zheng Ren to come over.
“Su Yun, look…” As Zheng Ren spoke, he suddenly thought of something and immediately said, “Chief Chen, use a micro-pump to reduce and control the patient’s blood pressure. The patient’s pain is severe so make sure to administer 5 mg of morphine first.”
Zheng Ren spoke very politely, but his expression was full of confidence and his tone was one that could not be rejected. It was the standard posture of a superior doctor.
Although Chief Chen was puzzled, he did not refuse. He immediately called for the nurse and administered 5 mg of morphine according to Zheng Ren’s instructions. Then, he installed a micro-pump and injected sodium nitroprusside into the vein to control the blood pressure.
Now that the patient could not be moved, Zheng Ren could not do anything even if he was anxious.
Although the blood pressure on the ECG monitoring was not high, there was still a possibility that the blood pressure would suddenly rise during the moving process and burst through the abdominal aorta.
He had to control the patient’s blood pressure first.
This was similar to the first time he went to the Imperial Capital and saw Cui Heming’s thoracic aorta dissection on the plane.
However, now that there were micro-pumps and various drugs, so everything was much better than the previous conditions.
Seeing that the other side was busy and would not be performing surgery for a while, Su Yun was unwilling. He grabbed Zheng Ren and asked, “How could you tell? The patient can’t be moved for the time being anyway. Let’s hurry up and talk about it.”
Zheng Ren nodded and walked to the doctor’s office with the radiographic films.
The radiographic film viewer was lit up, and there were two radiographic films inserted onto it.
Zheng Ren tidied up the radiographic films inserted on the radiographic film viewer. He found the film bag, checking the time and name on the upper right corner before putting it away. After that, he inserted the patient’s abdominal CT scan that was done because of the pain he felt onto the radiographic film viewer.
“Here, look carefully,” Zheng Ren said. “It looks very normal, like a normal vascular structure. But do you feel that the density is different from the surrounding blood vessels?”
He pointed at a point on the radiographic films and said with certainty.
Su Yun stared at the position where Zheng Ren’s finger was, his expression very strange.
“It’s like this, you arrange the pixels according to the digital matrix, and you turn it upside down. Er… It’s quite difficult to explain but can you visualize it?”
Su Yun glanced at Zheng Ren and said with disdain, “You mean that the digital matrix pa.s.ses through a digital converter, and each number is converted from black to white with different gray levels of pixels. After that, it’s arranged according to the matrix?”
This was the basic principle of CT imaging and Su Yun naturally understood it. But if it was reversed… What would he see?
“If you know then give it a try. If it’s reversed, you’ll get the most basic data. After that, follow it up with the 64-slice CT scan with 3D-image reconstruction, converting it again.”
Su Yun was stunned.
This conversion meant treating the human brain as a machine, a high-frequency machine at best.
Was this something that a human could do?
The arrogance in his eyes turned into countless doubts. He looked at the radiographic films inserted into the radiographic film viewer and was speechless for a long time.
After Chief Chen finished arranging the nurses’ work, he also followed up to see how things were doing on their end.
He was very curious about how Zheng Ren made the diagnosis.
As an old imaging worker, the hospital had imported a machine when Chief Chen was younger. If it was broken, he had to repair it himself.
Therefore, he understood what Zheng Ren said more clearly than Su Yun.
But… Could such a thing really work?
“Doctor Zheng, did you build a 64-slice CT scan with 3D-image reconstruction in your own mind?” Chief Chen asked in puzzlement.
“It’s not that exaggerated.” Zheng Ren smiled and said, “If all the data were reconstructed, it would be very difficult to do. But if we were limited to this point, the data that needs to be reconstructed would be much less. It would make it relatively easier.”
‘Is he truly that powerful?’ Chief Chen thought to himself. In his opinion, it was definitely impossible to do it, but Doctor Zheng only said that it was very difficult, not that it was completely impossible!
“I understand!” Su Yun slammed the table in front of the radiographic film viewer and said loudly, “Here, it’s a vascular intima fault!”
“Yes,” Zheng Ren said. “When you’re injured, your blood pressure will rise instantly and the blood vessel intima will rupture. “However, because of the ma.s.sive amount of blood loss, his blood pressure dropped immediately. There was no major problem with the blood vessel intima. After the interventional procedure, the bleeding blood vessels were all embolized. This caused the patient’s blood pressure to gradually rise, causing the intima rupture of the abdominal aorta to begin tearing again.”
“Boss, you only needed to take a glance to know.” Su Yun was a little puzzled. There was no problem with the diagnosis. He even thought that Zheng Ren’s words were nonsense.
The key point was that Zheng Ren had restored the CT image to the original data and then reconstructed it. This speed was simply too fast!
Moreover, Su Yun did not ask the biggest question on his mind—how did Zheng Ren determine that there was a problem at that particular point?
Zheng Ren pointed out the location. He had to calculate it in his mind for a long time before he could restore and reconstruct it. Furthermore, when he brought the radiographic films, he casually said to prepare for emergency surgery.
‘He really is a monster,’ Su Yun grumbled in his heart.
“I’ve watched too many radiographic films so I had a gut feeling,” Zheng Ren said perfunctorily.
Although Chief Chen knew, he was too old. His brainpower could no longer perform such complicated calculations like when he was young.
According to the normal procedure, the patient needed to be brought to the CT room for a vascular CTA examination before he could be diagnosed. After he was diagnosed, he could bring up the surgery form and place a stent in the patient’s abdominal aorta. This would solve the problem.
Before interventional surgery, aortic dissection was a serious and fatal disease. With interventional surgery, as long as it could be diagnosed, anything other than type 1 aortic dissection was a small problem.
As long as it was interventional radiography, the position of the aortic dissection could be seen on the image. There was no need to do a 3D reconstruction of the blood vessels.
However, this was only if the diagnosis was 100% accurate.
Chief Chen hesitated.
