Abstract:
1. A method of warning when a planned dose of radiation will exceed a predetermined limit, said method comprising the steps of: imaging a tissue mass to obtain imaged data that identifies abnormal tissue that require radiation therapy and normal tissue that radiation therapy should attempt to avoid; utilizing a system computer to access reference databases that contain dose tolerance limits for said tissue mass; utilizing an electronic display; generating a dose volume histogram that plots at least some of said imaged data versus proposed doses of radiation, wherein said dose volume histogram presents a data curve that is displayed on said electronic display; recalling at least one dose tolerance limit from at least one of said reference databases for said tissue mass; displaying said at least one dose tolerance limit on said display with said data curve to produce a modified dose volume histogram; analyzing said at least one dose tolerance limit and said data curve with said system computer to determine if said data curve surpasses said at least one dose tolerance limit at any point along said data curve; and automatically generating a visual warning indicator on said electronic display should said data curve surpass said at least one dose tolerance limit at any point along said data curve.
