According to the news from Han Ting, Director Peng will not come to Z Hospital for a few days, and he plans to take a few days of annual leave to take Warlene to see the latest real estate.

Therefore, in the past two days, in addition to dealing with the scientific affairs meeting, he also arranged the next affairs of the department first, unless there is an urgent patient to deal with, there is nothing important not to disturb him.

However, he didn't mention it to Wallen, and the reason he gave himself was that he didn't want Wallen to bother.

In fact, he knew in his heart that he didn't tell Warlene in advance for a reason he didn't want to admit it, that is, his mother's words had been hovering in his mind and affecting his thinking.

While he was thinking about buying a wedding house, he was tormented by the assumption of leaving Warlene, two diametrically opposed ideas were entangled in his mind, and he couldn't tear apart, and Han Ting felt that he was about to demonize.

However, Han Ting's plan did not come to fruition because Director Peng came earlier than he expected.

On the third day after Wallen was injured, Director Peng came to Z Hospital, and Lang Shaomin came back with Director Peng.

As soon as Director Peng arrived, he summoned several people who were about to work in the radiotherapy building, namely Lang Shaomin, Warlene, Fei Nali, and Director Peng himself, and held a meeting to arrange the rest of the week's work.

The linear accelerator data measured by the Provincial Environmental Protection Bureau has been faxed to the Medical Affairs Office, because Vice President Tian, who is also the director of the oncology department, does not understand radiotherapy, so he did not receive the data, and instructed the Medical Affairs Office to give the data to Director Peng after Director Peng took up the radiotherapy building, so after Director Peng came to Hospital Z this time, the Medical Affairs Office gave the data to Director Peng as soon as possible.

But Director Peng didn't plan to use this data, he wanted to measure the data himself.

"The three-dimensional water tank measurement data is indeed fast, time-saving, and coherent, but the measured data also has its shortcomings," Director Peng explained to Worling, "When the three-dimensional water tank measurement data is measured, the probe has been swimming in the water, causing the flow of water, and when actually treating patients, the human body tissue is fixed, although the body fluid in the tissue is moving, but there is no large flow amplitude of water caused by the three-dimensional water tank measurement data, so there is still a gap between the two."

"If the probe is set up to move too fast in order to be in a hurry to measure the data, the amplitude of the water flow will be too large, and this gap is even greater. ”

This Warlene didn't expect that Chen Xinyu and the senior brothers and sisters of the Provincial Environmental Protection Bureau hadn't told her, and it seemed that she still had a lot to learn.

"Again," Director Peng added, "when measuring the data of the three-dimensional water tank, in order to measure a series of data at one time, the number of ray hops given each time is relatively large, sometimes even thousands of hops at a time, and if the machine emits rays for a long time, the probability and amplitude of dose rate fluctuations are relatively large, and the measured data is not suitable for actual treatment."

"Because the actual number of hops is generally only a few hundred when doing the actual treatment, the probability of the dose rate being kept at a stable value is relatively greater, and whether the dose rate is stable or not has a great impact on the consistency of data measurement. ”

Warlene thought carefully about Director Peng's words and felt that it did make sense.

When she came out of the beam heat engine, she found more than once that if the number of ray beats she gave at one time was relatively large, the dose rate was relatively stable at the beginning, and the dose rate would fluctuate later.

Noticing that Wallen was thoughtful about her words, Director Peng was quite satisfied with Wallen's performance.

He continued: "One of the linear accelerators used by our hospital, oh, the provincial hospital where I was originally located, is already the most advanced accelerator in the world, and there is still a phenomenon that the dose rate is often unstable, not to mention that the model of this machine is old.

"It's not that the model of the machine is old, the dose rate must be unstable, according to my survey statistics, most linear accelerators will have a dose rate fluctuation when a large dose of radiation, I have been engaged in radiotherapy work for many years, I have seen and heard of radiotherapy machines are very complete, these models of accelerators are without exception.

"So, every time my original radiation oncology department buys a new machine, I ask them to re-measure the data according to the actual treatment situation, and I only use the data that we measured ourselves.

"Older linear accelerators are more common for unstable dose rates at large doses. This type of linear accelerator used to be available in the provincial hospital. ”

The implication is that he has used this type of linear accelerator from Z Hospital and knows its performance very well.

Wellen couldn't really ask a problem with this, because she had only seen a linear accelerator in her own hospital so far, and the performance of the machine she knew was very limited.

If she wants to know the performance of this machine well, she has to contact this machine for a long time in the future, and she has to wait for the opportunity to understand the other models of machines that Director Peng said in the future, so at present, what Director Peng said, she can only bury a question mark in her mind.

However, she still has questions about the data measured with the three-dimensional water tank and the data measured with the point dose: "Director Peng, will we use all the data measured by the point dose in the future, or will it be combined with the data measured by the three-dimensional water tank and comprehensively applied?"

"I heard that hospitals with radiotherapy machines in the province will borrow the three-dimensional water tank measurement data of the Provincial Environmental Protection Bureau.

Director Peng said: "That's right, we also borrow their 3D water tank measurement data, but other hospitals want to borrow their 3D water tanks, they have to use their people, but we don't use their people, we operate our own people."

"All the data we measured, but also we process it ourselves, I have reported to the hospital to buy a three-dimensional water tank before I retire, it is said that the hospital has approved, I don't need it!"

Although he did not emphasize this time, we also understood that the "we" he was referring to here meant that he was leading the radiotherapy team in the provincial hospital.

Director Peng felt very sorry for not being able to operate the three-dimensional water tank of his own department in person.

Warlene thought about something beautiful: "Hehe, with Director Peng here, if we borrow the three-dimensional water tank of the provincial hospital, will the cost be cheaper?"

"Yes, if we want to use the three-dimensional water tank in the future, we will borrow it from the provincial hospital," Director Peng was touched by Wo Lin's words, "In this way, I can personally use the three-dimensional water tank I bought by myself." ”

Although he said a lot of shortcomings in measuring data with 3D water tanks, he was still eager to personally operate the 3D water tank in his department: "The data measured by the 3D water tank and the data measured by the fixed water tank have their own advantages and disadvantages.

"I'm afraid you won't be able to digest it at once, so let's measure the data, and I will tell you about the specific application of the data in the process of liberation therapy, and also add something to do that can lift your spirits when measuring the data. ”
