"Okay!"

Although Baker and Western said this, he was actually a little worried that it had been too long, but Western said that this patient was very special, there was a lot of damage inside and out, and there was no way to know what was bad without looking carefully. And I just swept it two hours ago, which is a little too frequent, and it's not a fossil.

This whole-body CT can be said to be the most expensive batch of instruments in the hospital, the fifth generation of products, more than 2,000 detectors and do not move, only the X-ray tube will rotate around the object being scanned, and the power consumption is not small, because it is not easy to excite X-rays on the chemical coating.

Although it cannot be said to be the treasure of the town, it is enough to have a large room on its own.

Baker has all the authority to manage it.

This is his baby, with his own nickname, called Xiaobei.

He skillfully entered new parameters into the keyboard, which was to determine a new scanning scheme, fully automated, computer-controlled high-tech, just a brain away from the automatic human body repair machine in science fiction.

"Okay, that's it, Xiaobei, let's work!" Baker muttered to himself, and Western next to him looked at him like he was looking at a psychopath.

"We'll be able to see every detail of this guy's body in a moment!" Baker said as his hand quickly hit the sure start.

"Uh-huh!"

Western nodded, he was familiar with CT machines, but he didn't have a license. Watching Baker proudly tapping on the keyboard, his heart was filled with disdain.

The principle of CT machine is not complicated. The absorption value of X-rays by various tissues of the human body, normal and abnormal state of the same tissue, is different. When the ray stream is shot out, it is like firing bullets continuously, hoping to receive its own warhead on the opposite target, and the few that are absorbed by the intermediate object are taken away.

The CT machine takes advantage of this feature to divide a selected level of the human body into many cubes, which are called voxels, like infinitesimal blocks in calculus.

When the rays pass through the human body, the density or gray scale of each voxel is measured, which is the basic unit on the CT image, called pixels, and when they are arranged into a square array of rows and columns, they form a rather vivid image matrix.

A special algorithm is used to calculate the grayscale of each pixel.

Every time you scan, you can get an equation, and after several scans, you can get a simultaneous equation, which does not need to be calculated, which is the work of the computer.

The simultaneous equation can be solved by computer calculation, and the X-ray attenuation value of each voxel is obtained, and then the different attenuation values of each voxel are converted to form different gray scales of each pixel, and the matrix image formed by each pixel is the black and white image of the different density organization at the level.

If Western is the one who invented the CT machine in front of him now, he has to show his respect, but Baker is only a technician who can read the operation manual, and even if the machine fails, he will only call the manufacturer to repair it, and it is impossible for such a person to make Western have the slightest respect.

"Dr. Western, I can use the speed I did last time I scanned the ornithosaurus egg fossil, but do you really think it's appropriate?"

"You swept the Ornithosaurus egg fossils?" Western was drawn to the remark.

"Yes, a private research institute brought something and wanted to see what structure was inside, I think they probably wanted to find some active substance!"

"What kind of ornithishosaur is it?" Western asked casually.

"I don't know, it looks like it's a little round stone, but they don't say it's a dinosaur egg, well, after sweeping it, they're right."

"Did you find the active substance?"

"How is that possible!" Baker shook his head, "Even if there were, it was killed by the rays!" Then again, there's a real danger, are you sure? He was referring to the fact that a careful scan of Shaun now could bring no small number of physical risks.

Western's face was serious: "From my point of view, this patient has been struck by severe lightning and needs to be carefully observed for damage in his body. He said in the tone of a doctor announcing his decision, hoping that Baker would understand what he meant.

Baker basically understood, that is, a lot of places in it were burned. In other words, it is very meaningful to use this kind of patient to practice his hands and courage in the treatment of waste utilization. And that's a poor Chinese boy, such a person won't cause any trouble.

"Lightning strikes, I heard about it, and the thunderstorm in the afternoon scared me out, and I heard that there was power outages in many places, and substations were destroyed. Well... This guy... Is he cooked? ”

"Five ripe!"

Western understated it, there was no sympathy, after becoming a doctor, his feelings towards human beings would become much indifferent, birth, old age, sickness and death were inevitable of life, and it was ridiculous to try to live people.

"Hah! Fifty percent? "Dr. Baker was a white, brown-haired man staring at the big machine that was humming slightly, and the people inside.

"I'm used to it, I usually go out and order steaks to order five ripe."

Such a topic is scary and unappetizing for the average person, but for the doctor, it is natural, as if the surgeon is always spitting and vomiting and is used to picking up a hot dog in front of the operating table and munching, and he doesn't even take off his gloves, isn't it all protein anyway?

Baker banged on the table, a little bored, sometimes looking at the screen, but not focused, mostly fiddling with something on his phone.

Instead, it was Western, looking at the screen for a while, and paying attention to the patient's movements inside.

Now do the most complex scanning scenario.

Although CT was developed from an X-ray machine, it is very different from traditional radiography.

Although both use X-rays that can penetrate the body, it is the difference between high-definition high-speed video recording and Polaroid camera photography.

In addition, the X-ray detection system used in CT is more sensitive than photographic film, and the data obtained by the detector is processed by computer. The peculiarity of this technique is that it distinguishes between X-ray absorption values that differ very little.

But what Western saw on the screen was a high-absorption image.

And every time he scanned the image, he felt a change, like the energy had been absorbed.

He swallowed softly, but did not speak, not intending to remind Baker of this.

…...

On the Los Angeles Highway, in a black Ford, Amrath hung up his phone: "Let Hassan stay in the hospital, let's go back first." ”

"Did Dans have a guy with him when he was caught?"

"He's smart, he didn't bring it." Amrath half-closed his eyes and lit a cigarette.

"He's not going to say anything, is he?"

"He knows the consequences!"
