PROBLEM TO BE SOLVED: To provide attenuation correction in positron emission tomography using magnetic resonance imaging.SOLUTION: A method includes: a step of performing a magnetic resonance (MR) imaging sequence to acquire MR image slices or volumes of a first station representative of a portion of a patient; a step of applying a first phase field algorithm to the first station to determine a body contour of the patient in the first station; a step of 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; a step of segmenting the first anatomy of interest based on the identified contour of the first anatomy of interest; a step of correlating first attenuation information to the segmented first anatomy of interest; and a step of modifying a positron emission tomography (PET) image based at least on the first correlated attenuation information. |
