1. A method of automatically detecting and quantifying white and brown adipose tissue from an imaging scan of a subject comprising:
- providing the imaging scan of the subject;
automatically detecting a body region of the subject in the imaging scan;
separating and segmenting subcutaneous adipose tissue (SAT) from visceral adipose tissue (VAT) in the imaging scan of the subject; and
detecting and segmenting brown adipose tissue (BAT) from other tissue in the imaging scan of the subject.

Abstract
A system and method for automatically detecting and quantifying adiposity distribution is presented herein. The system detects, segments and quantifies white and brown fat adipose tissues at the whole-body, body region, and organ levels.

14. A method of creating a risk profile of a subject by automatically detecting and quantifying white and brown adipose tissue from an imaging scan of the subject comprising:
-
providing the imaging scan of the subject; automatically detecting a body region of the subject in the imaging scan wherein the body region detected is an abdominal region or a thorax region; separating and segmenting subcutaneous adipose tissue (SAT) from visceral adipose tissue (VAT) in the imaging scan of the subject; detecting and segmenting brown adipose tissue (BAT) from other tissue in the imaging scan of the subject; and creating a risk profile based on the quantitative amount of VAT and BAT found in the subject. - View Dependent Claims (15, 16, 17, 18)

19. A method of automatically detecting and quantifying white and brown adipose tissue from an imaging scan of a subject comprising:
-
providing the imaging scan of the subject wherein the imaging scan is a positron emission tomography/computed tomography (PET/CT) scan; automatically detecting a body region of the subject in the imaging scan; separating and segmenting subcutaneous adipose tissue (SAT) from visceral adipose tissue (VAT) in the imaging scan of the subject comprising; segmenting total adipose tissue (TAT); estimating a SAT-VAT separation boundary; removing outliers using geometric median absolute derivation (MAD) and local outlier scores (LoOS); and fusing labels of boundary candidates across different slices of an image volume to create a fine SAT-VAT separating surface; detecting and segmenting brown adipose tissue (BAT) from other tissue in the imaging scan of the subject comprising; identifying TAT in the imaging scan; performing automatic seed selection for BAT; performing image co-segmentation; and differentiating BAT regions from non-BAT regions. - View Dependent Claims (20)
