In general it seems you need to apply domain for a view to filter and show only some records based on condition. Please see the videos showing the different use cases of domain in odoo.

Hi Niyas Raphy
Thanks for your answer but that was not my problem.
I had already managed to display the types of radiology and line of Exams according to the somatic region.
I just wanted that by clicking on one of my lines of exams that I could retrieve the ID of my Radio Request but I managed to find a solution.
