Terzo giorno – affiancamento e primi task guidati. Il quarto giorno – riunioni con dipartimenti chiave e feedback intermedio. Il quinto giorno – revisione settimanale, definizione obiettivi a breve termine e integrazione culturale.
Mappa mentale per l’analisi della formazione francese ai Mondiali 2026. Punti chiave: attacco stellare guidato da Mbappé, con triplice minaccia (profondità, taglio, sponda). Criticità: centrocampo poco creativo – la costruzione offensiva dipende dagli attaccanti che arretrano. Difesa solida (Upamecano, Saliba, Koundé). Portiere Maignan. Variabili: gestione infortuni e condizione fisica dei big. Ideale per scout, giornalisti e tifosi.

position fixation technology
Overview
significance
The entire treatment course needs to be completed multiple times, so internal fixation is required to ensure the repeatability of each treatment.
A treatment usually lasts for more than ten minutes, so position fixation is required to ensure the stability of the patient's position during treatment.
Radiation therapy is different from radiation diagnosis. It has high energy and is very destructive. In order to improve the tumor control rate and protect normal tissue as much as possible, we need to increase the position accuracy.
Purpose
Determine the patient’s treatment position during treatment
Limit patient movement during treatment, improving precision
Reduce daily treatment setup time and reduce patient waiting time before treatment
Precautions
The position fixator should be selected with good penetration, good comfort, not easy to be damaged, and easy to operate.
Try to be as standardized as possible in clinical operations
When encountering special patients, specific problems should be analyzed in detail
Postural immobilization and assistive devices
thermoplastic film
characteristic

The shaped model is easily deformed if exposed to heat sources.
Postural fixation frame
head holder
Head, neck and shoulder board
Arm holder
Breast dedicated fixation rack
All-in-one rack
headrest
Position fixation for head and neck radiotherapy
body position
supine position
prone position
Side decubitus position
Other positions
Head fixation process
Adjust the head mount
The fixed frame is adjusted by laser to keep it consistent with the longitudinal axis of the bed surface.
Posture design
Select body position, headrest, and position the patient
Adjust patient position
Use laser light to fine-tune the patient's position so that the midline of the patient's body is consistent with the longitudinal axis of the bed
thermoplastic film fixation
Place the thermoplastic mold into a constant temperature water tank at 60~72°
Precautions
If female patients have long hair, it is best to cut it before undergoing membrane treatment.
Oropharyngeal cancer patients need tongue depressors or dental trays to protect their tongue and teeth
Neck patients are best served without a top to maintain reproducibility, while head patients may wear thinner, softer tops
Position fixation for radiotherapy of chest, abdomen, and pelvic tumors
body position
supine position
prone position
Position fixation process
Same head position fixation process
Features
Adopt the prone position and the abdomen will naturally droop, effectively reducing the load on the small intestine.
Applicable diseases: rectal cancer, cervical cancer (abdominal and pelvic position fixation)
Precautions
The accuracy of radiotherapy is greatly affected by bladder filling, small intestinal peristalsis, supine and prone positioning, and urine-holding training and appropriate body position selection are required.
There is a lot of pelvic sweat secretion, and the marking line is easily blurred. Pay attention to protection.
Position fixation for breast cancer radiotherapy
body position
prone position
supine position
Side decubitus position
Other positions
Fixed process
Adjust the fixing bracket
The fixed frame is placed slightly on the affected side of the treatment bed
Posture design
Select body position, headrest, position the patient, and pay attention to the patient's arm function
Adjust the height of the base plate of the mounting bracket
Make the fixed plate and the bed surface form a wedge-shaped angle to correct the inclination of the patient's chest wall
Heat shrink film fixed
Place the thermoplastic film into a constant temperature water tank at 60~72°
In special cases, the individuation body is fixed
