Ulceration of the lower limb is a growing clinical problem with significant economic impact on the NHS. Such ulcers are currently assessed by visual estimation of changes in surface area and depth, which is both subjective and potentially unreliable, especially in relation to wounds of irregular shape. More objective methods of measurement which can assess changes in wound volume would be advantageous in monitoring changes and in the assessment of the efficacy of clinical interventions. This study investigated the Di3D stereophotogrammetry system which allows fast, high-resolution, photo-realistic remote determination of 3D surfaces. A lower-limb model was developed and imaged to compare measurements by Di3D to those made by Vernier callipers. Physical and digital landmarks were placed on the model and on the computer generated surface. Five cavities of clinically relevant volumes were modelled and imaged to investigate the accuracy of volume measurement by Di3D and 3D volume analysis software. The system showed a mean linear measurement difference of 0.33mm and volume measurement difference ranged from -2.22% (for the largest cavity) to +8.54% (for the smallest). This study demonstrates that Di3D can accurately reproduce and quantify 3D surfaces and may be of clinical value estimating the 3D parameters of lower-limb ulcers.
