NCT03403361

Brief Summary

The aim of this protocol is to refine the accuracy of proton beam therapy (PT) by the use of dual energy computed tomography (DECT), in conjunction with novel iterative image reconstruction algorithms, to more precisely determine the tissue properties through which the proton beam path travels.

Outcome Measures

Primary Outcomes (1)

  • Dose Difference in 99% Planning Target Volume (PTV) Coverage Between Single Energy CT and Dual Energy CT

    Day 1

Study Arms (1)

Dual-Energy CT scan

EXPERIMENTAL

Patients enrolling in this study will undergo additional sequential DECT scan in addition to their routine SECT or DECT scan.

Device: Siemens Somatom Definition EdgeDevice: Philips Brilliance Big Bore CT/simulator

Interventions

In addition to acquiring medically-routine datasets, each patient subject will be scanned sequentially at two or three different beam energies (80 or 90 kVp, 100 kVp, 120 kVp, and 140 kVp) as part of this research study.

Dual-Energy CT scan

In addition to acquiring medically-routine datasets, each patient subject will be scanned sequentially at two or three different beam energies (80 or 90 kVp, 100 kVp, 120 kVp, and 140 kVp) as part of this research study.
