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.

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 compare the effect of the non-magnetic screen on the blocking of the patient's breathing versus the current procedure (the blocking of the breathing is informed by the staff) The patients will each receive 5 sessions of radiotherapy on Linac MRI. 100 patients are expected to participate in this study Before each session will be assessed for anxiety and stress. After each session will be evaluated patient satisfaction, pain intensity and respiratory effort. The duration of the treatment and therefore of the follow-up of the patient in the study is 1 to 2 weeks

RECRUITINGThe 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.
Time frame: During 25 months
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
Time frame: During 25 months
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
Time frame: During 25 months
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.
Time frame: During 25 months
The potential time
Evaluate whether the potential time savings in screen time compensates for the time spent learning the screen during the simulation.
Time frame: During 25 months
The patient satisfaction evaluated with an ad-hoc questionnaire.
The patient's satisfaction with his or her involvement in the treatment process will be evaluated at the end of the 5 radiotherapy sessions using an ad-hoc questionnaire.
Time frame: During 25 months
