Abstract :

Conformal/Standard radiotherapy wedges present several bioengineering-industrial design difficulties to obtain an optimal beam/beamlets-IMRT upper-surface radiation distribution, avoiding so that they could emerge undesirably from lateral walls instead the lower wedge plane. We calculated the improved exact beamlet limit-angle mathematical method for a standard/ conformal wedge filter design. It was developed with basic mathematical algorithms, geometrical design, and Numerical Simulations linked to this mathematical formulation. All that was done using the AAA algorithm integral attenuation exponential factor [AEF] which modulates the convolution kernel of the integral dose delivery. Results comprise the geometrical design of the conformal wedge, showed in several sketches, and simulations with appropriate software. In addition, a series of geometrical formulas/tables for the beamlets limits, trigonometric AEF background, and mathematical formulation with the simulations of the AEF for a 2-steps conformal wedge are obtained.
