Actual (reported)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.

Day 1
Patients enrolling in this study will undergo additional sequential DECT scan in addition to their routine SECT or DECT 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.
