Non-Invasive Determination of Muscle Tissue Size

Provided is a non-invasive system and method of determining muscle tissue size based on image processing. The method includes receiving at least one ultrasound scan image of at least a portion of a skin layer as disposed above one or more additional tissue layers, the image provided by a plurality of pixels. The method continues by introducing noise into the pixels of the image and thresholding the pixels of the image to provide a binary image having a plurality of structural elements of different sizes. The method continues with morphing the structural elements of the binary image to remove small structural elements and connect large structural elements. With this resulting image, the method distinguishes muscle tissue from remaining elements and determines the muscle tissue size. Associated apparatuses and computer program products are also disclosed.
