The cross sectional human anatomic atlas of the lower limb is an interactive tool based on MR axial images of the human leg.
Anatomical structures of the lower limb (hip, thigh, knee, leg, ankle and foot) and particular regions (compartment of the lower limb) are visible as dynamic labeled images.

A magnetic resonance imaging (MRI) was performed on a healthy subject; with an axial spin-echo T1 weighted acquisition covering the entire human leg.
From a PACS (Picture Archiving and Communicating System), data and DICOM images were exported as JPEG images. Resizing, and colors have been made with the Adobe Photoshop. The software Macromedia Flash allows us the development of an atlas based application with an amazing functionality and user interface for exploration of the human skeleton anatomy.
This module is a comprehensive and affordable learning tool for medical students and residents and especially for physicians, anatomists, rheumatologists, orthopedic surgeons and radiologists. It is also a fundamental communication tool to teach patients anatomy and pathology.
It provides access to an atlas and to images in the axial planes, allowing the user to learn and review orthopedic anatomy interactively. Images are labeled, providing an invaluable teaching resource.
We used the Terminlogia Anatomica to create anatomic labels. This terminology is the international standard on human anatomy (it supersedes the previous standard, Nomina Anatomica since 1998). It was developed by the Federative Committee on Anatomical Terminology (FCAT) and the International Federation of Associations of Anatomists (IFAA).

The horizontal menu gives access to groups of anatomical structures that can be chosen by the user:
- Arteries
- Veins
- Muscles
- Ligaments
- Tendons
- Bones
- Nerves
As the cursor is moved over a particular compartment of the lower thigh or the leg, that compartment is highlighted and labeled: anterior, medial, lateral or posterior compartment.
The vertical left menu provides an illustration of a skeleton lower limb based on a three dimensional (3D) model that simplifies the access to the anatomical regions.
The test mode allows comprehensive evaluation of user progress during his learning path.
