Fan Gong saw that Cao Liang and Warin had something to say, so he left first.

Warlene asked Cao Liang, "What's the matter?"

Cao Liang sighed: "Originally, I was going to go to you after work, my son has dysentery, it has been three days, with a high fever does not go away, originally I don't advocate the use of hormones, but if the fever does not go away, I am afraid that my son will burn out, and today I will be equipped with hormones."

"There was something wrong with the MRI yesterday, I tried to make do with it first, and I didn't repair it at night, but I couldn't delay it any more tonight, but my daughter-in-law and mother-in-law were scared, and I had to watch my son at home at night, and I was also worried that my son would suddenly have a problem. ”

Warlene understood: "Okay, I'll try to fix it at night, but it really can't work, I have to come with you." ”

Although the MRI has not yet passed the warranty period, if there is a minor problem, it still has to be repaired by the hospital itself.

Because there are very few MRI maintenance engineers in China, each maintenance engineer is responsible for several provinces at the same time, and many times, when the machine fails, the maintenance engineer is busy repairing the machine in other places.

During the installation of magnetic resonance, Wallen followed from beginning to end, but after all, she had never been exposed to magnetic resonance since then, and she was not confident that she could rule out the problem of magnetic resonance that Cao Liang said.

Cao Liang was a little excited: "Thank you, the problem is not difficult to solve, if you can't think of how to solve it, just call me, let's discuss, if this is not possible, we can only ask the engineer to repair it." ”

"Okay. Without hesitation, Warlene agreed.

"Thank you so much, go back to Corey. Cao Liang didn't say more.

He knew that Wallen didn't want to miss any opportunity to learn, and he also knew that engineers, engineers have their own work schedules, and they won't wait for anyone's eagerness to learn and delay the process of installing and debugging the machine.

When Warlene returned to the radiotherapy building, Fan Gong was already preparing for the filming of Kouno, and as soon as Wallen entered the simulator's machine room, he began to explain every step he had done before, and his subordinates did not delay further movements.

After explaining the preparation procedures for filming, Fan Gong went on to explain: "In the future, you will do all this work, and I rarely have the opportunity to come over again, the principle of the simulator is much simpler than that of the accelerator, and it is not difficult to maintain, and you can basically solve it by telephone guidance." ”

Warleen nodded.

The next steps, Fan Gong explained very carefully, if there is something that Warlene does not understand, he will ask clearly, or if Fan Gong finds it more difficult to understand, he will also ask Warlene if she understands, whether Warlene understands it or not, he will explain it again.

The film was filmed, and Fan Gong was accompanied by Warlene to the perspective room.

At this time, there were many patients who wanted to take films, so Cao Liang didn't care about helping to wash the film, so he asked Fan Gong to wait a while.

"Brother, you're busy, I'll just wash it myself. Fan Gong didn't care whether Cao Liang agreed or not, and entered the dark room after speaking.

When Fan Gong came out of the film washing, the film box was filled with new film.

Back in the simulation room, Fan Gong used a ruler to measure the actual light field shot by the verification film, and the error was more than five millimeters.

"No, it's too big. Fan Gong instructed Warlene to disassemble the head of the simulator, and the two of them worked together to adjust the light of the light field.

After the debugging, the film was filmed again, this time the filming work was to let Warlene move his hand, and Fan Gong was correcting on the side.

After that, every time he took a verification film, Fan Gong still washed the film by himself and changed the film by himself.

After repeated six verification films, the error between the light field and the actual irradiation field was less than one millimeter, and it seemed to be almost completely consistent with the naked eye, and Fan Gong was satisfied.

In the domestic standard, the error range within two millimeters is qualified, and the requirements of Fan Gong are higher.
