"High-end fabrics, comfortable and snug fit, with details that highlight quality. From the details to the whole, we strive for the ultimate perfection. Customization is not just a service, but also an attitude. ”
If you think this is an advertisement for a clothing brand, are you mistaken? In fact, this is the first step in the process of precision radiotherapy - body position fixation. In this process, it is necessary to design the best position for the patient and make a mold. And this mold, just like the high-end customization, should be personalized design and production according to the contour of each person's body, close to the comfortable body, high-end atmosphere.
Sun Yat-sen University Cancer Prevention and Treatment Center Radiologist Shang Lintao Teacher is talking! Today we will start the content of the first lecture in a "haute couture clothing" way - "private custom, your personalized mold"!
The machine is cold, the ray is ruthless, and we want to be the best teacher with temperature.

Sun Yat-sen University Cancer Center.
Radiologist, Sun Yat-sen University Cancer Prevention and Treatment Center; Deputy Chief of the Provincial Youth Civilization No. 1, Science Popularization Correspondent of China Anti-Cancer Association, and Lecturer of Guangdong Province Cancer Prevention and Treatment Science Popularization.
He is good at the design and production of body position fixation of radiotherapy patients, CT simulation positioning and MR simulation positioning technology, the implementation of radiotherapy, and the popularization of radiotherapy-related precautions.
He has won the third prize of the first Guangdong Provincial Cancer Prevention and Treatment Science Contest (speech category) and the Excellence Award of the 4th Southern Health Science Contest (** category).
Precise radiotherapy, quality control first. Radiotherapy quality control is the guarantee of patient safety!
.What is posturing? The perfect integration of quality and life, the ingenious collision of the whole and the details
Positional fixation is the application of positional fixation devices for patients to ensure the accuracy, reproducibility and comfort of the future position, which is an extremely important part of the design and implementation of tumor radiotherapy plan, and runs through the entire radiotherapy process.
To put it simply, according to the patient's physical condition and radiotherapy needs, choose the most suitable position and make a suitable mold.
Positioning techniques during chest radiotherapy.
.Why immobilization? Man depends on clothes and horses on saddles
The right position and mold can improve the best results and reduce the incidence and severity of adverse reactions! Mainly embodied in:
1) Keep the target area to be irradiated as far away as possible from other normal organs.
2) Reduce the patient's change in body position due to discomfort or breathing movements, etc.
3) Ensure the consistency of the patient's position in multiple times, that is, repeatability.
4) Timely detection of changes in the patient's body in order to adjust the ** plan and reduce the adverse effects caused by changes in body shape.
5) Compared with marking directly on the mold, marking on the mold can prevent the marking line from blurring or deformation and dislocation due to factors such as pulling or sweating.
.Why should the mold be personalized? Customization is not just a service, but also an attitude.
There are thousands of molds in the warehouse, and there is only one with you.
You may ask: why not make a mold that all patients can use for positioning? Save time, effort and worry.
It's a pity, the ideal is very plump, but the reality is very skinny. First of all,Different types of materials are used in different partsTo make molds, different diseases have different requirements for molds, which will greatly affect the accuracy of the mold; Secondly, even if it is the same part and the same diseaseEveryone's body shape is also differentThe so-called "universal mold" cannot fully fit the body of every patient, and it will naturally lack repeatability and comfort.
Just as ill-fitting clothes can't highlight the advantages of your figure, inappropriate molds can't escort your ** perfection.
.How should the patient cooperate when the position is immobilized? Give me a trust and give you a perfect mold
In the process, how to cooperate with the master to make a perfect mold?
1.Relax and trust the radiotherapist and radiologist
Each of the positioning fixation methods used in the hospital has been found to have its advantages after a large number of data comparisons. According to the patient's physical condition and radiotherapy needs, the corresponding fixation method can be used to maximize the accuracy, reduce the error, and enhance the effect.
2.Read carefully the preparation written in the leaflet
For example, do not wear collared shirts such as shirts or polo shirts, remove hoods, and accessories; Emptying the bowel and filling the bladder, fasting, etc.
3.During the period of asemblematic fixation, cooperate with the ** division
Obey requests: e.g. take off your shirt,** or take off your outer pants; lying or lying on your stomach; Raise or hang your hands up or down at your sides, etc.
4.The body relaxes
Each patient's mold will follow the patient to the end of the treatment, so when making the mold, the patient must find the most comfortable position for himself, and communicate with the master in time if there is any problem. If the position is uncomfortable due to tension when making the mold, and the repeatability of the position is poor, it will eventually affect the accuracy of the follow-up.
