Claim 0:
1. A method for detecting and creating magnetic resonance imaging anatomical outlines of a subject, comprising:
acquiring magnetic resonance imaging signals of a selected region of interest of the subject's anatomy;
processing the magnetic resonance imaging signals to determine image pixel intensity of one or more pixels associated with the selected region of interest surrounding a center location which is predetermined to not contain cerebrospinal fluid (CSF); and
calculating a mean intensity value associated with the center location;
determining an interior anatomical outline of an anatomical area of the selected region of interest containing CSF, the interior anatomical outline surrounding the center location, wherein image pixels with an intensity value greater than the mean intensity value by a first threshold amount are designated as part of the interior anatomical outline, and wherein a perimeter of the interior anatomical outline encloses the center location; and
determining an exterior anatomical outline of the anatomical area of the selected region of interest containing CSF, the exterior anatomical outline surrounding the interior anatomical outline, wherein image pixels with an intensity value less than the mean intensity value by a second threshold amount are designated as part of the exterior anatomical outline, wherein a perimeter of the exterior anatomical outline encloses the interior anatomical outline.
