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

Eligibility Criteria
You may qualify if:
- Diagnosis of histologically proven primary or metastatic cancer requiring thoracic radiation therapy OR radiation therapy to the head and neck or brain
- At least 18 years of age.
- Planning to undergo proton or photon beam radiation therapy as part of the clinical management of the diagnosed cancer.
- Able to understand and willing to sign an IRB-approved written informed consent document.
You may not qualify if:
- Implanted metallic objects in the region to be scanned excepting dental prostheses
- IV or oral contrast medium within 24 hours prior to DECT image acqusition
- Pregnant.
