| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have been developed an automatic detection system for anatomical landmarks in CT images. The system utilizes a non-sparse multivariable Gaussian statistical model on inter-landmark distances. The aim of this study is to extend our previous method to sparse multivariable Gaussian model by GPGPU-implemented Graphical lasso method. The probabilistic distribution of inter-landmark distances was estimated as a multiple Gaussian distribution with a sparse precision matrix. Feasibility of improvement of the landmark detection accuracy with this novel inter-landmark distance model was evaluated. | |
