| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a method to estimate displacements of pancreatic cancer based on multidimensional features of multiple surrounding organs for real-time radiation therapy. Multidimensional features which consist of displacements of vertices between maximal inspiratory state and maximal expiratory state are obtained by shape registration to target 4D-CT data. The result of the experiments showed that the proposed method could estimate the centroid of the displacements of pancreatic cancer with an error of $2.75 pm 1.70$ mm using LASSO regression from the features of stomach, liver, left and right kidney and duodenum. And the proposed method selected the center of displacements of liver, duodenum and left kidney as effective features. | |
