Abstract
The present invention relates to a system for measuring a muscle mass of a specific muscle. The system receives a plurality of MRI (Magnetic Resonance Imaging) tomographic images acquired by scanning along a single axis of a muscle to be measured, calculates a location, contour, and fat fraction of the muscle to be measured based on the images, and ultimately calculates a volume excluding fat of the muscle to be measured. Accordingly, the time required for measuring muscle mass can be reduced, and a measurement result close to an actual value can be obtained.

A system for measuring a muscle mass of a specific muscle, comprising:
- an input unit configured to receive a plurality of MRI (Magnetic Resonance Imaging) tomographic images acquired by scanning along a single axis of a muscle to be measured;
- a position extraction unit configured to estimate a location of the muscle to be measured based on the plurality of images received by the input unit;
- a contour generation unit configured to set a boundary line of the muscle to be measured based on the estimation result of the position extraction unit;
- a fat fraction calculation unit configured to calculate a fat fraction inside the boundary line set by the contour generation unit;
- and
- a muscle mass calculation unit configured to calculate a volume excluding fat of the muscle to be measured based on the boundary line set by the contour generation unit and the calculation result of the fat fraction calculation unit for the plurality of images received by the input unit.
A method for measuring a muscle mass of a specific muscle, comprising:
- (a) inputting a plurality of MRI tomographic images acquired by scanning along a single axis of a muscle to be measured;
- (b) estimating a location of the muscle to be measured based on the plurality of images;
- (c) setting a boundary line of the muscle to be measured based on the result of the location estimation;
- (d) calculating a fat fraction inside the boundary line;
- and
- (e) calculating a volume excluding fat of the muscle to be measured based on the boundary line and the fat fraction calculation result for the plurality of images.
