Load and deformation in the calcaneal/heel region are often studied because of their potential for pain. Research conducted before proved that the calcaneal region receives large loads, both standing and walking, mainly due to excessive body weight. While heel pad deformation is not always associated with body weight, but its influenced by the mechanical properties of plantar soft tissues. In the older person the deformation of the calcaneal region while standing is lower than the adult person, which indicates the loss of the elasticity of the heel pad in aged adults. The aim of this study is estimating deformation of calcaneal area while standing from the Boolean Operation between 3D and footprint image of foot which is a novelty. Thirteen patients who feel pain due to calcanea spur were asked to volunteer research (3 males and 10 females, age 56 ±10 years old, and BMI 25.53±3.74 kg/m2). The 3D image is obtained from 3D scanner for foot orthotics, while the 2D footprint image is obtained from the digital footprint scanner. To determine the accuracy of this method compared with the deformation result of lateral x-rays due to its own weight.
