Chang Chang, PhD, a leader in proton therapy medical physics, has been named Director of Physics at Texas Center for Proton Therapy.
Previously, as Senior Medical Physicist at ProCure Proton Therapy Center in Somerset, New Jersey, Dr. Chang was involved in the commissioning of new proton technology (including pencil-beam scanning treatment) and the RayStation treatment planning system for both passive and pencil-beam scanning proton treatments.
Pencil-beam scanning in conjunction with on-board cone-beam computed tomography gives clinicians a three-dimensional view of a patient’s anatomy for more precise treatment. Pencil-beam scanning uses precise ultra-fine proton beams across each layer of the tumor. ■
