The Self-Orienting Imaging Device and Methods of Use sense the orientation of the handheld imaging, and apply the rotational correction by rotating the image to be displayed. When a scanner is used, the scanning element in the scanner is adjusted, such that the eventual scanning direction remains unchanged referencing the subject anatomy. The self-orienting mechanism for the scanner may be implemented in hardware mechanisms.
