Figures & data

Figure 1. Impact of the thickness (left), GT (Middle), and geometrical CTC (right) on the actual throughput generated by tungsten MSC of 30 mm thickness.

Figure 2. (a) Energy spectra of proton beam before and after a collimator. The number of protons is normalised to the peak value of the maximum energy layer. Panel (b) and (c) show depth-dose curves (at peak and valley) with and without collimator, non-optimised, and optimised for homogenous dose in the PTV for the in vivo setup described in Overgaard et al. [Citation12].
