Phantom study demonstrates that a unified Hounsfield look-up table supports dual-energy and single-energy CT for accurate dose calculation in radiotherapy.
Key Points
Dose calculations show minimal differences between single-energy and dual-energy CT plans, indicating compatibility.
CT numbers were closely matched across three SECT methods, affirming the reliability of DECT in clinical settings.
Phantom scanning with dual-energy CT revealed acceptable clinical agreements in dose calculations for various body regions.
Implementing a unified Hounsfield look-up table may streamline workflows, facilitating a transition to dual-energy CT.
