In the iso dose shift method for correcting inhomogeneity, where is the shift of the isodose chart for bone located?

In the iso dose shift method for correcting inhomogeneity, the shift of the isodose chart for bone is located towards the skin. This is due to the higher density and atomic number of bone compared to surrounding soft tissue, which leads to increased attenuation of the radiation dose. As a result, the dose distribution is affected, causing the isodose lines to shift.

In regions where bone is present, the radiation slows down more than in soft tissue, which effectively means that the isodose lines, which represent the distribution of radiation dose, will need to move closer to the surface of the skin in the area where the bone is located. This shift is essential for accurately planning and delivering radiation treatment, ensuring that the intended dose reaches the target area while accounting for variations in tissue density.
