Benefits and considerations in using a novel computed tomography system optimized for radiotherapy planning

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

“…In addition to CT innovations driven by diagnostic requirements, several CT applications with RT purpose were introduced recently. Special reconstruction kernels for SECT provide images with information on mass density or electron density independent from the selected tube voltage, which can be directly used for photon dose calculation without the need of voltage-specific HLUTs [16] , [36] , [37] , [38] . This allows for optimising the image contrast by automatically selecting the most suited tube voltage for each patient and body region examined.…”
