Explore our advanced lower limb CT anatomy library, featuring high-resolution anatomical images presented in the axial plane. This comprehensive learning module has been developed using thin-slice CT imaging to demonstrate clinically realistic cross-sectional anatomy of the lower extremity.

The lower limb section covers the major bones, joints, muscles, tendons, ligaments, nerves, blood vessels and soft-tissue compartments from the hip to the foot. Important structures include the femur, patella, tibia, fibula, tarsal bones, metatarsals and phalanges, together with the hip, knee, ankle and foot joints.

The muscular anatomy includes the gluteal region, anterior, medial and posterior thigh compartments, quadriceps muscles, hamstrings, adductor muscles, calf muscles, peroneal muscles and the intrinsic muscles of the foot. Fascial compartments and intermuscular planes are clearly demonstrated to support the understanding of lower limb cross-sectional anatomy.

The module also demonstrates major neurovascular structures, including the femoral artery and vein, profunda femoris vessels, popliteal vessels, anterior tibial vessels, posterior tibial vessels, peroneal vessels, sciatic nerve, femoral nerve, tibial nerve and common peroneal nerve.

Joint anatomy includes the acetabulum, femoral head and neck, patellofemoral joint, tibiofemoral joint, proximal and distal tibiofibular joints, ankle mortise, subtalar joint and the joints of the foot. Important tendons and soft-tissue landmarks are also identified where clearly visible on CT.

Each axial CT image is manually labelled slice by slice in a textbook-style format, without the use of AI auto-labelling tools. This helps maintain anatomical accuracy and provides a reliable learning reference for radiologists, orthopaedic surgeons, trauma specialists, radiology trainees, reporting radiographers, physiotherapists and students studying cross-sectional anatomy.

The labelled images are displayed within a smooth interactive scroller, allowing users to move naturally through the anatomy in the same way they would review a clinical axial CT examination. The platform works on desktop and mobile devices, while the full-screen viewer supports detailed examination of small anatomical structures.

The toolbar allows users to search for specific structures using voice or text search. This helps users quickly locate important landmarks such as the sciatic nerve, femoral vessels, quadriceps muscles, hamstring muscles, popliteal vessels, tibial nerve, common peroneal nerve and major lower limb joints.

The side zoom tool provides up to 10× magnification without loss of image quality, allowing users to examine fine anatomical details and better understand the relationships between bones, muscles, joints, vessels, nerves and surrounding soft tissues.

This module is supported by dynamic Level 1 and Level 2 quizzes that generate new questions during every session. These interactive assessments help users actively revise, test their knowledge and retain complex lower limb CT anatomy.
