Advances in dual energy computed tomography approach for proton stopping power ratio computation in radiotherapy

Figure 3 Individual tissues stopping power ratio relative error for the presented dual energy methods as presented in Chika[21]. The relative stopping power ratio estimating error for each tissue is plotted against the reference (actual) stopping power ratio on the graph. This is plotted for different methods as shown in figure legend where f_r (μ)= μ_L/μ_H. Citation: Chika CE.
