4D Study of Thoracic Cancer Radiation Treatment. Edition No. 1
VDM Publishing House, May 2010, Pages: 140
Thoracic tumor moving due to respiration is the challenge in radiotherpay today. Four-dimensional (4D) radiation treatmen planning was proposed to solve the tumor with motion problem. In this book, we applied the deformable image registration, called optical flow method (OFM), to deal with integral radiation dose through time as dose mapping. Validations of a dose mapping program using OFM, and to demonstrate application of the programin radiotherapy follow-up evaluation were discussed detail in book. For the purpose of validation, the deformation matrices between 4D CT data of different simulated respiration phases of a phantomwere calculated using OFM. The matrices were then used to map doses of all phases to a single-phase image, and summed in equal time weighting. Besides, several clinical cases with proposed method were all pesented in this book, too.
