Magnetic resonance imaging (MRI) is an advanced medical imaging technique used to scan the body of a patient to discover abnormalities in soft tissues and bones. The preparation of the MRI room consists of several interconnected phases: fabrication and installation of the radio frequency (RF) cage, leveling the room floor, preparation of the quench pipe and safety exhaust fan. The preparation of the floor is very critical for obtaining image quality. The floor should be leveled to minus 20-25

A small deviation in the leveling can cause noises to the magnetic homogeneity and affect the diagnostics. Hence, the image can be distorted and produce incorrect diagnosis and treatment. Due to the importance of the subject, precision needs to be achieved during construction. We suggest leveling the MRI floor using a scraping robot. Leveling procedure is achieved by regulating the moving speed of the robot and the depth of the scraping edge using Fuzzy logic controllers.
