I think it's an x-ray room. The wall with the window for the radiologist to look through and the arm above the table.
Strange to have chairs in the room. Minor correction, it would usually be a radiographer not a radiologist who took x-rays. However if this was a screening room (a room that does imaging with a fluoroscopic unit), it would usually be a radiologist who did it.
The chairs are definitely interesting. I can't think of any rooms like that where family or friends have been allowed. Maybe we're both right and it's a multipurpose "hospital" room? Might make sense for a small town that needs a doctor's office with basic exam capabilities.
