Abstract
The objective of this study was to explore Laws’ masks as a new application of texture analysis to characterise bone micro-architecture and to check its dependence from the spatial resolution. The method is based on masks that aim to filter the images. From each mask, classical statistical parameters can be calculated. Our study was performed on 114 women with osteoporotic fractures and 182 age-matched healthy post menopausal women. For all subjects radiographs were obtained of the calcaneus with a new high-resolution X-ray device. The bone mineral density measurements were assessed by DXA.
