摘要：
The present disclosure provides a system and method for method for quantifying radioactivity production during a proton treatment of a patient. In some aspects, a method includes administering, using a proton delivery system, a proton treatment using at least one therapeutic proton beam generating positron emitting radionuclides within a region of interest (ROI) of a patient, and acquiring, using an emission tomography system, emission tomography data indicative of an activity of the positron emitting radionuclides in the ROI. The method also includes quantifying, based on a kinetic model, a radioactivity production rate of at least one positron emitting radionuclide using the emission tomography data. The method further includes generating at least one map indicative of the radioactivity production rate of the at least one positron emitting radionuclide.
