The patients eligible for the study are those treated by radiotherapy on Linac MRI for a mobile cancerous lesion (pancreas, liver, kidneys, adrenals, lung, adenopathy above or below the diaphragm ...).
After signing the consent form, each patient will be randomized to one of two treatment arms:
* Standard arm : Radiotherapy treatment with Linac MRI without non-magnetic shielding * Experimental arm : radiotherapy treatment with Linac MRI with non-magnetic screen The aim is to evaluate the effect of using a non-magnetic screen visible to the patient in the bunker during radiotherapy sessions delivered by Linac MRI on decreasing the ratio between the actual treatment time and the treatment time predicted by the machine.
Patient is at least 18 years old
Patient starting radiotherapy on Linac MRI for a mobile cancerous lesion most often in the pancreas, liver, kidneys, adrenals, lung, supra or subdiaphragmatic adenopathy
Patient affiliated to the social security system
Patient with lesions not detected by the device's tracking system
Patient with visual disturbances
Contraindications to treatment with Linac MRI (epileptic patients, pregnant or breastfeeding women, metallic prosthesis or pacemaker not compatible with MRI)
Patients with cognitive disorders
Parallel
With non-magnetic screen
Combination productRadiotherapy treatment with Linac MRI is performed with a non-magnetic screen that will guide the patient to block the breathing
The effect of the non-magnetic screen during radiotherapy (Change in ratio of actual treatment time to the treatment time predicted by the machine).
To evaluate the effect of a non-magnetic screen visible to the patient in the bunker during radiation therapy sessions delivered by Linac MRI on decreasing the ratio of actual treatment time to the treatment time predicted by the machine.
Patient respiratory effort with visual analog scale
Patient respiratory effort for each radiotherapy session according to randomization arm. The scale is graduated from 0 to 10 with 10 = maximum respiratory discomfort and 0 = no respiratory discomfort
The positional pain with visual analog scale
Compare the positional pain associated with setting up on the treatment table for each radiation therapy session according to the randomization arm. The scale is graduated from 0 to 10 with 0 = absence of pain and 10 = maximum pain
Level of anxiety/stress evaluated with the Spielberg scale via the STAI-Y-form grid
To assess the average level of anxiety/stress for each radiation therapy session according to the randomization arm. The Spielberg scale via the STAI-form Y-A grid is used before each treatment session in order to follow the evolution of the patients' emotional state. 20 questions with 4 possible answers : 1/ Not at all, 2/ A little, 3/Moderately , 4/ A lot.
The potential time
Evaluate whether the potential time savings in screen time compensates for the time spent learning the screen during the simulation.
