Generation of predetermined isodose inclination with the use of a motor driven wedge filter

The polynomials obtained differ from energy to energy. The differences in isodose inclination angles increase with irradiation time using a 60° wedge. The higher is the energy of the beam, the greater is the inclination of the isodoses using the same physical wedge. The differences between the results of measurements in a solid phantom and in a water phantom are due to the differences in depth dose distributions between both materials.
