Abstract
A method and apparatus are provided for modeling circulation in a living subject. The method includes the steps of developing a model for living subjects in general and correcting the model to substantially conform to the overall cerebral physiology of the living subject. The method further includes the step of calculating a cerebral flow of the living subject based upon the corrected model and a selected cerebral blood flow perturbation.
Claims20
A method, comprising:
- displaying selected views of a 3D image of a portion of a patient's vasculature derived from 3D MRI volume data;
- selecting a particular image plane of the 3D MRI volume data from the 3D image;
- calculating a 2D image corresponding to the selected image plane from the 3D MRI volume data;
- defining a region of interest around a selected blood vessel in the 2D image, refining the region of interest to obtain the border of the selected blood vessel, and calculating a center point of the blood vessel;
- deriving a set of center points of the selected blood vessel from the 3D MRI volume data as the selected image plane is moved generally along the length of the selected blood vessel;
- and,
- defining a location and slice orientation for phase contrast magnetic resonance angiography corresponding to a selected pair of the identified center points.

An apparatus, comprising:
- means for displaying selected views of a 3D image of a portion of a patient's vasculature derived from 3D MRI volume data;
- means for allowing selection a particular image plane of the 3D MRI volume data from the 3D image;
- means for calculating a 2D image corresponding to the selected image plane from the 3D MRI volume data;
- means for allowing definition of a region of interest around a selected blood vessel in the 2D image, refining the region of interest to obtain the border of the selected blood vessel, and calculating a center point of the blood vessel;
- means for deriving a set of center points of the selected blood vessel from the 3D MRI volume data as the selected image plane is moved generally along the length of the selected blood vessel;
- and,
- means for defining a location and slice orientation for phase contrast magnetic resonance angiography corresponding to a selected pair of the identified center points.
