WebThe use of CBCT scans for dose calculations has followed two main approaches: the first is mapping the FBCT numbers to the CBCT geometry (Yang et al 2007, Chao et al 2008). Yang etal (2007) have used CBCT data for anatomical definition and then deformably registered with the conventional fan-beam CT (FBCT) to show a dose agreement within … WebImage guidance technologies are significantly diverse, rendering their classification challenging. Image guided radiation therapy (IGRT) can be distinguished into the following four systems, each one having different characteristics and imaging goals: cone beam CT (CBCT), fan beam CT (FBCT), planar imaging, and nonionizing visualization []. ...
