Abstract:
1. A method, comprising: causing a magnetic resonance (MR) imaging system to perform a magnetic resonance (MR) imaging sequence to acquire MR image slices or volumes of a first station representative of a portion of a patient; applying a first phase field algorithm to the first station to determine a body contour of the patient in the first station; identifying a contour of a first anatomy of interest within the body contour of the first station using the first phase field algorithm or a second phase field algorithm; segmenting the first anatomy of interest based on the identified contour of the first anatomy of interest; correlating first attenuation information to the segmented first anatomy of interest; acquiring a positron emission tomography image; modifying the positron emission tomography (PET) image based at least on the first correlated attenuation information; perform a magnetic resonance (MR) imaging sequence to acquire respective MR image slices or volumes of a plurality of additional stations; modeling a containership of fat within bone marrow for every station in which the patient's bone is present to determine a cortical bone contour; and segmenting the cortical bone based on the cortical bone contour to generate a cortical bone mask.
