METHOD FOR REAL-TIME DOSE RECONSTRUCTION DURING RADIOTHERAPY

摘要

A method for real-time dose reconstruction during radiotherapy or particle therapy, such as proton therapy, from a radiotherapy/particle therapy beam source, comprising the steps: a) selecting one or more points in the space exposed to radiotherapy/particle therapy; b) projecting at least one of the points to at least one plane intersected by the central axis of a radiotherapy/particle therapy beam projecting from the radiotherapy/particle therapy beam source; c) calculating dose in the plane(s) generated by the radiotherapy/particle therapy beam; d) depth scaling the dose in the plane from the projected points to the selected points, thereby obtaining delivered doses in the selected points; and e) iteratively repeating the above steps b)-d).
