Abstract: This thesis is an investigation of capacity of textural content of ultrasound (US) images to differentiate between contraction levels in a healthy population. Changes in muscle contraction on (US) images has thus far been examined using structural parameters such as fiber angle and muscle thickness. It was hypothesized that increases in contraction would result in decreases in the average entropy of US images, and significantly influence the textural content of US images of the biceps brachii and brachialis. The results demonstrated no significant differences in entropy across contraction levels (p=0.73). The results of a repeated measures MANOVA performed for features identified using PCA suggested that the textural content of US images varied significantly (p<0.0005). These results demonstrate that textural content of US images differs significantly with changes in contraction of skeletal muscle. Future investigations may investigate the relationship between textural content of US images and physiological changes due contraction.
