Patent ID: 7834624

Claim:
A method for detecting a position of an examination person in a magnetic resonance scanner, comprising the steps of: placing an examination person on a moveable table and operating the table with computerized system to move the examination person on the table at least partially through the magnetic resonance scanner; irradiating the examination person on the table with at least one RF pulse while the examination person and the table are moving through the magnetic resonance scanner, and thereby causing magnetic resonance signals to be emitted from the examination person that are insufficient by themselves for image generation; optimizing said at least one RF pulse to give a magnetic resonance signal originating from predetermined body tissue, at a known location within the examination person, a differing signal characteristic that differs from magnetic resonance signals originating from a remainder of the examination person; detecting said magnetic resonance signals correlated in said computerized system with moving the table through the magnetic resonance scanner; and automatically electronically determining a position of the examination person in the magnetic resonance scanner using only the acquired magnetic resonance signal, which has said differing signal characteristic, from the predetermined body tissue correlated with moving the table through said magnetic resonance scanner.
