Abstract

The human heel pad thickness, defined as the shortest distance between the calcaneus and heel skin, is one of the intrinsic factor which must be taken into account when investigating the biomechanics of the heel pad. US and MRI are the preferable imaging modalities used to measure the heel pad thickness as they are both ionizing-free radiations. The aim of this paper is to measure the bone to skin distance of nine heel pad phantoms from MRI and US images, and to compare the results with a true value (TV) in order to find the errors. Paired sample t-test was used to compare the measurements. Results showed a statistically significant difference between MRI and US1540 (P-value=0.005), and between TV and US1540 (P-value=0.013). Furthermore, results showed no statistically significant difference between US1530 or MRI and TV (P-value=0.103 and P-value=0.358, respectively), and between MRI and US1530 (P-value=0.402). Results confirm the necessity to investigate on the real speed of sound for the heel pad tissues, in order to have realistic measurements when dealing with human heel pads. __________________________________________________________________________________________________________
