Description

Title of Image: 'Beneath the Surface'. Cortical bone mapping of hip from computed tomography (CT). This image depicts a novel image analysis technique called 'cortical bone mapping'. This technique can measure the thickness of cortical bone (the dense outer shell-like layer) at many thousands of points around the hip from clinical CT scans, plotting the results as a colour wash on a 3D model here viewed from the front. The following colour scale corresponds with these approximate cortical bone measurements: red 0.0 mm; orange 1.2 mm; yellow 2.4 mm; green 3.6 mm; blue 4.5 mm; purple 5 mm+. These measurements can be used to test whether individuals are at risk of a hip fracture if the bone is too thin, or if they might be developing osteoarthritis if too thick. Using a mesh in this case to display results rather than a more usual surface representation reveals the complex framework that is the basis for 3D sampling of the underlying CT imaging data.
