Texture analysis methods based on gray level co-occurrence matrices can be optimized to probe the spatial information from knee MR T2 maps and of the changes caused by osteoarthritis. Curvature of the cartilage surfaces and relatively low resolution in relation to cartilage thickness set special requirements for texture analysis tools. Here we report an optimized analysis tool with customized point-wise offset angle and endpoint extrapolation for cartilage texture analysis. Method provides excellent performance compared to traditional texture analysis implementation.
