A system for medical emergency care and monitoring of a patient includes as its first component a patient holding apparatus with a fixed base and a table mounted on it, and the table protrudes past the base on the head end with a radio transparent first region and on the foot end with a radio transparent second region. There is also a CT scanner which is movable on the floor along a guide element in such a way that the second region of the table can be brought, by moving the CT scanner, into the patient opening of the CT scanner. For taking x-ray images in the first region of the table, there is an x-ray unit. Another component pertains to a guided patient board that is ridable on the table in the longitudinal direction.
