The influence of dual-energy computed tomography image noise in proton therapy treatment planning

From computed tomography innovation to routine clinical application in radiation oncology – A joint initiative of close collaboration

“…DECT is a promising CT acquisition technique and has been proven to be advantageous in RT [23] , [24] , [25] , [26] , [27] , both for delineation [28] , [29] and dose calculation [30] , [31] , [32] , [33] , [34] . However, the clinical transition from conventional CT to DECT is not only a simple change of scan protocols, but it impacts the entire RT chain from delineation and treatment planning to image registration at the treatment machine before dose delivery.…”
