Dear fluka experts
As fluka medical application introduced.We are able to simulate beam dose distribution in Dicom Material. To learn this function i build an basic proton beam model as an test example. A mono energetic 3*3cm proton beam placed close to patient surface(Y direction). And inject into patient body,the HU conversion file is head.mat in FLUKA dicom module. According to the bragg peak in proton therapy, the hot dose region should located in the tail region as fig 1 shows.
However, the head region(where mainly material is air) dose is much higher than tail region which is opposed to physical model as fig 2shows.
