Shou Weiguo didn't know who he was, how old he was, and who his parents were. He was rescued by Li Zongrong by chance, and he followed Li Zongrong for more than 30 years.
Li Zongrong named him Shouweiguo in the hope that he would be healthy and contribute to the motherland.
Li Lei is much younger than Shouweiguo. It can be said that Li Lei was brought up by Shouweiguo. In name, Li Lei calls Shouweiguo his elder brother. In fact, in the eyes of Shouweiguo, Li Lei is almost his son. Li Lei needs Shouweiguo. Generally speaking, Shou Weiguo would not refuse to do things.
Just like tonight, Shou Weiguo really wanted to stay at home with Wo Lin, but he didn't want Li Lei to be in trouble. After sorting out the dishes he bought, Shou Weiguo didn't even eat dinner at home, so he took a quick shower and went mourning hall.
Warin is used to the days when Shou Weiguo occasionally comes home but rarely stays at home. She made dinner and left enough for Shou Weiguo to eat, and then moved the small dining table to the yard, enjoying the evening breeze and eating Eat dinner slowly and enjoy this rare comfort.
?The reason why we have to leave food for Shou Weiguo is because often when Wo Lin thought that Shou Weiguo had eaten, Shou Weiguo ran back hungry.
Shou Weiguo's friends sometimes half joked and half complained in front of Wo Lin, asking if Shou Weiguo didn't like the meals they served at all because of the beautiful food at home.
Ordinarily, Shou Weiguo should not come back during the vigil tonight, but who can say for sure.
In the middle of the meal, Warin received a call from Director Peng: "Don't forget that I made an appointment for two positioning scan patients yesterday. I made an agreement with Director Liang. The scan will start at 7:30 tomorrow morning, so don't be late! "
Fortunately, it wasn't a problem with the machine, Wallin was glad, otherwise she would be a night owl again tonight.
Although Wallin is working as a physicist, because of the part-time maintenance of radiotherapy equipment, when the equipment breaks down is not determined by human resources, so Wallin's working hours are also flexible.
If there is a breakdown in the instrument, it is best to fix minor problems immediately. If the breakdown is serious and it will take a long time, Warin will have to find a way to temporarily make the instrument work normally. Working overtime to maintain instruments.
The so-called temporary method, one method is to change from automatic to manual. This is relatively safe, but it will take more time and effort during treatment.
There is another way that Warin needs to monitor the whole process when treating patients, and that is to cancel the safety chain of the instrument. If the instrument is not restricted by the safety chain, it is easy to cause accidents due to operational errors.
However, if the safety chain is not cancelled, the patient will not be happy if the machine is shut down for maintenance for safety reasons.
Most of the radiation therapy patients are inpatients. If one day's delay in radiation therapy is delayed, the patient will have to pay an extra day of hospitalization fees. Some patients sell their houses and animals to raise money for treatment, and they really cannot afford to delay.
Outpatients are also not happy about the long downtime. They don't stay in the hospital like inpatients. They have to come from home every day. Some people have to take a car early in the morning, and it takes several hours to go back and forth.
There are also people who need time for treatment. For example, a nasopharyngeal cancer patient admitted to the radiotherapy department was a high school teacher in a county. This teacher changed classes with other teachers almost every day. After the treatment, go back to school as soon as possible, and try not to delay the class for the students.
Four years later, the teacher's cancer cells metastasized to the brain, and now he is receiving radiation therapy. He still took the time to come here every day. He still rushed back to school after the radiation therapy in order not to delay the class for the students.
For patients like this teacher, Warin would rather work hard on herself than delay the patient's treatment.
However, the above is only a failure of the low-voltage part. Warin can still find a way to keep the instrument running temporarily. If the high-voltage part fails, there is no way to make do.
The ultimate goal of radiotherapy equipment is to treat tumors with radiation. If the high voltage fails, the equipment will not be able to emit radiation, or the radiation cannot be emitted normally, so it has to be shut down for maintenance.
Warin worked overtime last night to repair the instrument. According to her flexible working hours practice, if Corey is not urgent, she can take a day off today.
The so-called urgent matters are equipment failures and making treatment plans for patients.
Originally, there was a treatment plan to be done today, that is, Director Peng said that the two patients who made an appointment yesterday were supposed to undergo a CT scan at 6 o'clock yesterday afternoon. Wasn't it because Warin was busy repairing the equipment and stayed up all night? Director Peng explained to the patient that it was changed to 7:30 tomorrow morning.
??The radiation therapy techniques performed by the Radiation Therapy Department of the former Z Hospital include external radiation and internal radiation.
?External irradiation is the electron linear accelerator plus high-pressure radiation, and performs external radiation therapy on tumors.
Internal irradiation is to send the radiation source to the inside of the body through the lumen, and perform radiation therapy on the tumor at close range.
Currently there are two types of external radiation therapy, one is ordinary radiation therapy, referred to as general radiotherapy.
The patient lies on the simulator, and through X-ray fluoroscopy, the tumor site is marked on the patient's body surface, and then the radiation dose is calculated according to the irradiated area of ??the body surface and the tumor depth, and then the patient can start radiation therapy.
The other is three-dimensional conformal radiation therapy, referred to as conformal radiation therapy.
Compared with the general radiation that simply draws a line from the body surface, passes through all normal organs, and directly reaches the tumor site, the operation of conformal radiotherapy is much more complicated.
Conformal radiotherapy is not fluoroscopy positioning under the simulator, but a 3D image of the human body reconstructed from the CT scan image through a specific radiation treatment planning system, outlining the 3D shape of the tumor and surrounding normal organs to be protected, and making a treatment plan .
The purpose of the treatment plan is to make the planned radiation dose reach the tumor site as much as possible, pass through the normal organs to be protected as little as possible, minimize the radiation damage to normal organs, and achieve the expected radiation dose at the same time. treatment effect.
Of course, the ray will not bend, which requires the path and angle of the radiation field designed in the treatment plan to avoid the normal organs to be protected as much as possible.
There is no CT machine in the radiotherapy department, and patients undergoing conformal radiotherapy can only go to the imaging department for scanning, and the conformal radiotherapy positioning scan is different from ordinary CT scans. The conformal radiotherapy positioning scan requires conformal radiotherapy supporting equipment and strict scanning positioning Requirements, which requires people from the radiotherapy department to do it in person.
Because of the strict requirements for conformal radiotherapy positioning, each conformal radiotherapy positioning scan takes much longer than ordinary CT scans. Director Liang is afraid of delaying the scans of ordinary patients in the imaging department. Position scanning is done after work, or before normal working hours in the morning, and an appointment must be made in advance.
Warin smiled wryly in her heart. In fact, there was nothing to be thankful for. Although it was not necessary to stay up late to repair the machine, it was not a good thing to look at other people's faces early in the morning.
Even if people don't show embarrassment, complaints are inevitable, and it is always inevitable to smile and say good things.
?Conformal radiotherapy patients need to finish scanning before going to work in the morning, and the imaging department has to arrange people to go to work early in the morning. In addition, the CT machine must be warmed up in advance, so the arranged people can get up earlier.
Although there are people on night shift in the Imaging Department, they sleep in the duty room and don't have to rush from home to the hospital in advance, but in such a hot day, who doesn't want to take advantage of the coolness in the morning to sleep a little longer.
