Body composition

Analysis using

Computed tomography image



Our tried and true legacy algorithm. ABACS™ 2D yields highly accurate body composition metrics and substitutes time-consuming manual segmentation with a highly efficient, fully-automated workflow that requires only minimal manual editing. 

ABACS 2D automatically segments skeletal muscle (SM), subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT) and intramuscular adipose tissue (IMAT) at L3 and T4 axial slices with incredible accuracy.

ABACS 2D is currently available in Data Analysis Facilitation Suite2.0

ABACS 2D is also available as a plugin in sliceOmatic by TomoVision.
