Witryna7 sie 2024 · When multiple scanning beam fields are used, it’s called intensity modulated proton therapy (IMPT). “The dose patterns of IMPT can overlap and intersect where the tumor has more bulk,” Koong says. This allows protons to treat even the most irregularly shaped tumors located around critical organs like the oral cavity, bowel or spinal cord. The original rationale for proton therapy was its highly conformal depth-dose distributions compared to photons, which allow greater sparing of normal tissues and escalation of tumor doses, thus potentially improving outcomes. Additionally, recent research has revealed previously unrecognized advantages of proton therapy. For …
