Uninvolved liver dose prediction in stereotactic body radiation therapy for liver cancer based on the neural network method

Figure 2 The neural network prediction model. A: Regression diagram of D_n0-D_n50 for the neural network prediction model; B: Regression diagram of D_n60-D_n100 and D_nmean for the neural network prediction model; C: The predicted value by the neural network model and the actual planned value. Pink is the predicted value of the neural network model; blue is the target planned value. D_nx = D_x (D_x: Dose of x% uninvolved liver volume)/prescription dose of planning target volume (D_prescription).
