Magnetic resonance imaging apparatus
First Claim
1. A magnetic resonance imaging (MRI) apparatus, comprising:
- an MRI system scanner including at least one computer configured to;
acquire three-dimensional MR image data including a target organ in a patient being imaged while disposed on a movable couch;
automatically detect region information providing a spatial domain imaging range including outer boundaries of the target organ in the three-dimensional image data; and
control movement of said couch based on a positional relationship between the region information detected from the three-dimensional image data and a magnetic field center.

Abstract
A magnetic resonance imaging apparatus according to an embodiment includes an acquiring unit, a detecting unit, a deriving unit, and an imaging controller. The acquiring unit acquires three-dimensional image data including a target organ. The detecting unit detects an upper end position and a lower end position of the target organ in the three-dimensional image data. The deriving unit derives an imaging range of subsequent imaging performed after acquisition of the three-dimensional image data based on the upper end position and the lower end position of the target organ. The imaging controller controls performance of the subsequent imaging in accordance with the imaging range.
