The present invention provides a kind of MRI system (100) and obtains MR data (158,168) from object. Executing machine-executable instruction (180,182,184,186,188) makes processor (144), is used for: receiving the image of the object of one or more internal structures (126) of (300) baseline (152) description medical images It receives (302) baseline scan geometry (154) Investigation obtains the MR data (158) of (304) from subject and passes through control magnetic resonance imaging system pulse train and survey data, wherein the data survey pulse train includes instruction, and the image of the object of the description three-D volumes (124) of MR data is acquired for controlling magnetic resonance imaging system It rebuilds (306) measurement MR data and is converted to three-dimensional survey image (160) (308) calculating position data are by handling three-dimensional survey image and organ detection algorithm (182), and wherein position data describes target area (128) The presumptive area (130) for distributing (310) uses the position data to three-dimensional survey image of concern It calculates (312) registration data (164), passes through record baseline medical image and three-dimensional survey image.
