Abstract
An MRI apparatus comprises a image producing unit 101 for producing an image of a first body part containing a blood vessel; a defining unit 108 for defining a slice intersecting the image based on a reference position Q within the first body part, the slice being defined so that an angle of the slice is changeable with respect to the blood vessel VE; a unit for obtaining an index VI for deciding whether or not the blood vessel VE is contained within the slice for each angle θ; and a determining unit 111 for determining an angle of the slice at which the blood vessel VE is contained in the slice based on the index VI.
Claims12
A blood vessel detection apparatus comprising:
- an image producing unit for producing an image of a first body part containing a blood vessel;
- a defining unit for defining a slice intersecting said image based on a reference position within said first body part, said slice being defined so that an angle of said slice is changeable with respect to said blood vessel;
- a unit for obtaining an index, said unit executing classification processing for classifying said blood vessel within said slice for each said angle and obtaining an index representing a result of the classification;
- and
- a determining unit for determining an angle at which said slice contains said blood vessel based on said index.
A magnetic resonance imaging apparatus comprising:
- an image producing unit for producing an image of a first body part containing a blood vessel;
- a defining unit for defining a slice intersecting said image based on a reference position within said first body part, said slice being defined so that an angle of said slice is changeable with respect to said blood vessel;
- a unit for obtaining an index, said unit executing classification processing for classifying said blood vessel within said slice for each said angle and obtaining an index representing a result of the classification;
- and
- a determining unit for determining an angle at which said slice contains said blood vessel based on said index.
A program for causing a computer to execute:
- image producing processing of producing an image of a first body part containing a blood vessel;
- defining processing of defining a slice intersecting said image based on a reference position within said first body part, said slice being defined so that an angle of said slice is changeable with respect to said blood vessel;
- processing of obtaining an index, said processing executing classification processing for classifying said blood vessel within said slice and obtaining an index representing a result of the classification for each said angle;
- and
- determining processing of determining an angle at which said slice contains said blood vessel based on said index.
