Stopping power ratio (SPR) residuals of dual- and single-energy computed tomography (DECT and SECT)-predicted SPR from reference values for the Gammex Phantom (A) and the Computerized Imaging Reference Systems (CIRS) Phantom (B). Effect of DECT SPR calculation on CIRS Phantom size (setup 1 versus 2) (C) and location of plugs (setup 2 versus 3) (D) within the full phantom. The SPR residuals using SECT and DECT are compared with measured SPRs of the CIRS phantom (E). Images of setups 1, 2, and 3 with the corresponding locations of the plugs circled in red (F).

(A) Color map showing stopping power ratio (SPR) differences between dual- and single-energy computed tomography (DECT and SECT) for head and neck treatment. Blue (red) region shows higher (lower) DECT SPR compared with SECT. (B–D) Axial view of head and neck SECT dose (B), the corresponding forward calculated DECT dose (C), and the DECT-optimized dose (D). Yellow and blue target contours are clinical target volume (CTV) 6300 and CTV 5400, respectively. Organ-at-risk (OAR) contours for constrictors (green) and left submandibular (yellow) are shown.

(A) Dose-volume histogram (DVH) of clinical target volume (CTV) 6300, CTV 6000, and CTV 5400 for the single-energy computed tomography (SECT) versus the double-energy computed tomography (DECT) optimized plans. Solid lines are the nominal doses, whereas corresponding dotted lines are the worst-case scenarios. Sample DVH bands for the right parotid (B) and brainstem and mandible (C) are shown for SECT optimization versus DECT optimization. The DVH bands correspond to worst-case scenarios of a 3-mm shift and 3.5% (2%) range uncertainty for the SECT (DECT) plans.
