Characterization of Bladder Motion and Deformation in Prostate Cancer Radiotherapy

- We implemented a population-based model to quantify uncertainties produced by bladder motion and deformation in prostate cancer radiotherapy.
- We obtained the directions of geometric variability using PCA that enabled us to characterize bladder shapes and motion/deformation region.
- As opposed to previous studies, we proposed a population-based PCA model using a voxel representation rather than surface points.
