At about half past eight, the first radiotherapy patient was personally accompanied by Dean Tian to the radiotherapy building.

Other entourage, including the head nurse of the oncology department, the patient's attending doctor, the patient's family, the officers of the hospital office and the medical office, photographers and reporters, and several other doctors in the oncology department who are not on duty, are a huge group.

Lang Shaomin, the actual radiotherapy doctor, walked at the back, but it was like a lively watcher.

Director Peng personally greeted this group of people at the door, I don't know, I thought what kind of celebration was being held here, there were guests and guests, the number of people was not small, and the scale was not small.

The group first visited the computer room, Director Peng gave a detailed introduction to the performance and function of the linear accelerator, and then except for Wo Lin and Li Bo, the others flocked to the third floor.

After a while, Fei Nali ran down from the third floor and called Warlene: "Director Peng told you to go up and start the simulator." ”

Only then did Warlene remember that she just didn't want to join in the fun, but she forgot that only she could use the simulator at present, and no one else had ever touched the simulator.

Warleen went upstairs, and Li Bo followed upstairs without saying a word, and wanted to follow up to see the lively Fenali, but had to stay in the linear accelerator operation room.

There must be someone on the first floor.

Fei Nali is a little unwilling, it is said that the process of admitting the first radiotherapy patient today will be broadcast on the city's TV station, she is not on the third floor, wouldn't she have to be absent from the TV program for a while, what a pity.

The mechanical movement of the simulator can be handled by just the operating table, unlike the linear accelerator, which also has a hand control box.

Therefore, Director Peng led the patient into the simulator room, let the patient lie on the machine tool, and drew lines on the patient's skin to mark the specific location of the tumor, while everyone else followed up, but Wallen stayed in the operating room and did not follow him.

She asked Li Bo: "Why don't you go in and see, this is a learning opportunity." ”

"There are too many people, but it's just a head. Li Bo finally opened Chrysostom.

"Brilliant!" Wallen gave a thumbs up to Libo.

Insiders look at the doorway, laymen look at the excitement, there are so many people, only Director Peng understands what he is doing, it is Lang Shaomin, it is estimated that he only knows a scratch, and the others are really as Li Bo said, they are all making heads.

This is a cervical cancer patient, after fluoroscopy with a simulator, Director Peng used a special Chinese medicine skin ink to mark the range to be irradiated on the patient's skin under the light field, measured the body thickness and width of the patient's irradiated area with calipers, calculated the distance from the tumor center to the skin surface, and then converted the irregular field into a square field, used the chart made of the measured data these days, found out the required data, and then used the formula to calculate the dose required for each time the patient was given radiotherapy, and filled in the radiotherapy treatment sheet.

"Alright, let's start the treatment now. After Director Peng's concluding remarks, the group went to the first floor again.

Wallen turned off the simulator and prepared to go downstairs.

The head nurse, who deliberately lagged behind, blamed Warlene: "On such a big day today, why don't you wear a white coat, and you have to take a group photo after a while, should you be counted as a patient's family member or a medical staff?"

"The hospital has a rule that medical staff must wear a white coat to work, and if they don't wear a white coat, they will be punished according to disciplinary violations.

Warlene explained: "Head nurse, it's not that I don't wear a white coat, it's that I don't have a white coat, Director Peng has already made an application report, and the warehouse says that there is no stock." ”

"Why are you waiting for Director Peng to make an application report, why did you go before," the head nurse's face sank suddenly, "When the oncology department was preparing for the opening, everyone received a white coat, what did you do at that time, you have to wait for Director Peng to come and be embarrassed." ”

Warlene explained: "When the oncology department was preparing for the opening of the department, I was studying in the capital, and within a few days of my return from the capital, the oncology department officially opened, and no one mentioned to me about getting a white coat. ”

"That's right," the head nurse's tone softened, "When I counted the number of people, no one mentioned you to me, I thought that everyone on the radiotherapy side had already gathered, and there was no verification, which was my responsibility." ”

She patted Warlene on the shoulder: "I'll urge the warehouse about the white coat, but now let someone borrow a white coat to send it to you, I'm afraid it's too late, and when it's time to take pictures, I'll wronged you not to participate." ”

Wallen smiled, "I haven't been in the fun since the beginning, so it doesn't matter if I take a picture or not." ”

The head nurse asked Li Bo, who was silent behind him, "Are you a new technician?"

"Yes. Li Bo nodded, not saying a word.

The head nurse smiled: "Sure enough, I don't like to talk, Cao Liang greeted me early in the morning, let me take more care of you, and I will also help you apply for your white coat, you just have to study with a few teachers and work hard." ”

"Okay, thank you!" Li Bo nodded.

"Hahahaha. The head nurse was amused by Li Bo's concise sentences, "Okay, this is another second Xiucai, the previous Xiucai, who always spoke in monosyllables, and even wished to omit monosyllables, and only recently said a little more words, but a sentence could not exceed five words at most." ”

After saying that, she laughed and waved her hand behind her, and the person had already rushed downstairs like the wind.

Warlene urged Li Bo: "You should also hurry down, it is your daily work to position the patient, and you don't want to make a head at this time, so you have to be there." ”

"Oh. Li Bo also rushed downstairs quickly.

Warlene went downstairs unhurriedly, remembering what the head nurse had just said when she mentioned Xiucai, she thought that Xiucai was enough to save words when she talked to her, but she didn't expect to be even more economical to others.

Xiucai talked to her, when a sentence was no more than six words, she would always have a word or no word to others, and when Xiucai was talking to her, she would not exceed five words in a sentence to others.

Warlene smiled knowingly, which shows that no matter how deep Xiucai's heart is hidden, it is still very special to her.

Walking downstairs unhurriedly, Wallen expected to see the lively scene as in the simulator room, but she didn't, she only saw Li Bo sitting alone in the linear accelerator operation room, and everyone else was gone.

"What about people?" asked Vollene.

"Went for a group photo. Li Bo looked out the door, "The office officer said that our machine has radiation, which is not good for the body, so there is no need to film the treatment process." ”

There was a mixture of flattering laughter from outside, but she couldn't see anyone else, Warleen smiled and shook her head: "This is the layman's misunderstanding of radiation, linear accelerators only produce radiation when the beam is released by high pressure, where does the radiation come from now, but to scare yourself." ”

The three big golden characters of "Radiotherapy Building" were not placed above the gate, but were pasted on the wall facing the main road, and the group was taking a group photo in front of that wall at this time, and Warlene naturally couldn't see them.

When the crowd dispersed, Lang Shaomin led the patients and their families back to the radiotherapy building, with a relieved look on his face.

Warlene teased Lang Shaomin: "Dr. Lang is going to be on TV, congratulations." ”

"Congratulations, fart," Lang Shaomin glared at Wo Lin hatefully, "You'll be hiding and don't be embarrassed." ”

The patient himself was very happy: "If you have this disease, you can go back to TV, and no one in our village has ever been on TV, and I am the first one." ”

Because cancer patients in the oncology department basically don't understand the new treatment method of "radiotherapy", and they have never heard of it before, the doctor said that when the radiotherapy building officially admits patients today, and talks to patients who are suitable for radiotherapy, most of the patients refuse to do radiotherapy.

The doctor's conversation with her was that her tumor was relatively large and the risk of surgery was relatively high, and preoperative radiation therapy could shrink her tumor, reduce the risk of surgery, and increase the possibility of cure.

The doctor also said that the first patient who was willing to do radiotherapy was free of charge, which was the most exciting thing for her.

Patients who are willing to do radiotherapy later, although there are also discounts on the cost of radiotherapy, there is no such thing as full exemption, and from next month, there will be no discount on radiotherapy fees at all.

After discussing with her family, she agreed to undergo radiotherapy.

"You are not only the first person in your village to be on TV, but you are also the first patient in our department to be treated by experts from the province," Lang Shaomin told the patient, "Our Director Peng is a radiotherapy expert from the province, and he is also proficient in chemotherapy, because you are the first radiotherapy patient, and in the future, our Director Peng will pay attention to your treatment throughout the whole process, and other patients have missed this good opportunity." ”

"What Dr. Lang said is true," Fei Nali, who came in later, just answered, "Auntie, this shows that you are lucky and have a wise decision, so you will encounter such a good thing." ”

The husband of the patient, who had not spoken for a long time, smiled: "Hehe, this is good, this is good." ”

Director Peng, who had sent the group away, came in at the end, and he beckoned the patients and their families to go to the doctor's office with him, and he wanted to explain to the patients some precautions when doing radiotherapy.

Although he had already talked to patients and their families in the inpatient department, now that he was at the treatment site, he felt that he still had to emphasize it again.

Lang Shaomin wants to learn from Director Peng, so naturally he has to go up together.

Only Fenali and Volin and Li Bo were left in the operation room, and Li Bo carefully recorded the operating procedures of the simulator in his notebook.

Wallen leaned over and glanced at Li Bo's notebook, and was surprised: "Wow, you just watched me operate, and you made the program so clear, it can't be that you have used different models of simulators before, right?"

Li Bo shook his head: "I haven't used a simulator, but I think the simulator is the same as the X-ray machine, but the operation procedure is more complicated." ”

Warlene agrees: "You're right, the simulator is an X-ray machine, but it has a higher milliampere and a longer duration of exposure. ”

She pointed out the error on Li Bo's notebook: "The numbers displayed on the workbench panel, these two are the light fields, and these two are the shooting fields, and the light fields and the shooting fields must be kept to coincide, so that the location of the tumor can be accurate." ”

Fei Nali suggested: "No matter how lively the discussion between the two of you is, it will be useless if you don't practice, so it's better to go up and teach by hand." ”

"Mr. Wol, is it okay?" Li Bo was eager to take advantage of Fenali's proposal and asked for Wollene's opinion.

"What's not to do," Wallen thought it was okay, "it's going to be useful anyway, so let's go up now." ”

As she spoke, Wallen went upstairs, and Li Bo followed.

Fei Nali muttered: "The hospital said that we should let the technician operate the radiotherapy machine, but did not say that we would operate the simulator, why are you so active, you are tired!"

In fact, she knew in her heart that the so-called radiotherapy machine recognized by the hospital should refer to the machines in the radiotherapy building in general, including simulation, but she just wanted not to be so energetic, why did she want to be in the same league as Li Bo, who didn't know what to do, what did he want to learn so actively, she rushed to be the same as him?

Besides, if they all go upstairs, who will stay on the first floor, if there are patients coming, how can they do without seeing people, if a leader comes, they think that all the staff have escaped from their posts, which is even more troublesome.

Finding a reason not to go upstairs, Fenali felt reasonable, so she insisted on staying in the linear accelerator operation room with peace of mind.

After talking with the patient and his family, Director Peng pasted the informed consent form signed by the patient on the attached page of the radiotherapy treatment sheet, and took the patient down for radiotherapy.

Seeing that only Fei Nali was alone in the accelerator operation room, and there was no one in the accelerator room from the monitor, Director Peng frowned: "Where did the others go?"

Fenali pointed her finger upwards: "I'm busy, I'm going to the simulator room." ”

Director Peng asked Lang Shaomin to go up and call Wo Lin and Li Bo: "Our first patient, to pay attention, must be present." ”

When Lang Shaomin entered the simulation room, Warlene was explaining to Li Bo the difference between Guangye and Shooting Field, and Lang Shaomin reminded in a low voice: "No matter how studious you two are, it depends on the time and occasion, hurry up, the patient has to be treated." ”

Volin and Li Bo hurriedly went downstairs with Lang Shaomin.

Seeing the somewhat cautious Wallen, and the inquisitive Li Bo, Director Peng didn't say anything, he asked the patient's husband to sit on a stool in the hall and wait, and led the patient into the linear accelerator room.

Naturally, the others didn't need to be instructed, and followed them into the computer room.

The patient's irradiation field is two pairs of piercing fields, one irradiated from the front and one irradiated from the back.

Director Peng demonstrated the position of the first field, let the patient lie on his back on the machine tool, the tumor site is within the range of the shooting field, and the center point of the skin surface in the patient's shooting field is kept at a fixed distance from the radiation source, which is called the source skin distance irradiation method.

Because the shooting field can only open the square field, and in order to protect the normal organs in the shooting field, the parts that need to be irradiated become irregular fields, so the parts that cannot be irradiated in the shooting field are blocked by the corresponding shape of lead blocks placed on the nose bracket.

In this case, the rack must be kept vertical at zero degrees, otherwise the lead block placed on the bracket will slide and will not play a role in protecting the organs, and if the rack is tilted badly, the lead block may fall to the ground.

Director Peng explained that Fei Nali used the hand control box to operate the linear accelerator, Lang Shaomin and Worin assisted from the side, and after setting up the patient, Director Peng instructed the patient: "From now on, until we open the door and come in, you don't move, and there will be a sound when the machine comes out, that's normal, don't be nervous." ”
