Intensity-modulated proton therapy (IMPT) is a highly precise type of radiation therapy using proton therapy. Intricate treatment planning and precise proton beam delivery results in modulating the intensity of the proton beam and shaping it to match the contours of the tumor. IMPT also provides the most conformal dose delivery technique for radiation therapy, “coloring” the tumor precisely within the lines prescribed by the physician. It also produces significantly fewer neutrons than other types of proton systems, and therefore delivers less radiation to healthy tissue adjacent to the tumor. This is especially important for pediatric patients who are at greater risk of developing neutron-induced secondary cancers later in life—and for patients with tumors in close proximity to critical structures that cannot be exposed to radiation.
