This is a superb cross-sectional atlas of the human upper limbs. It is based on sectioned images with a pixel size of 0.06 mm from the Visible Korean dataset. The images are in 48-bit true color and cover nearly all bones, muscles with tendons, ligaments, vessels, and nerves in the limbs. In this atlas, the entire shapes and locations of these structures can be identified in the horizontal, coronal, and sagittal planes. This book offers detailed topographical knowledge of human anatomy. Furthermore, it serves as a valuable reference for radiology, aiding in the precise localization of small and complex structures as well as lesions.
