Advanced Physics for Brachytherapy 2018

Lesson learned?

• DECT calculations for low energy sources within 4% of ground truth ➢ 7 tissue bins SECT at <9%; 3 tissue bin (like EBRT) failed!

• DECT very sensitive to noise and motion

➢ May make DECT difficult for patient imaging (CT dose / mAs settings) ➢ Simultaneous imaging

• Still a very active field of research!
