Figure 1 Value obtained over the course of the eleven fractions for both adaptive modes (blue for ATP and red for ATS) for the first patient, the acceptable range is represented in green, with darker shades denoting the optimal value.

Figure 2 Value obtained over the course of the eleven fractions for both adaptive modes (blue for ATP and red for ATS) for the second patient, the acceptable range is represented in green, with darker shades denoting the optimal value.

Conclusion:

The ATS mode demonstrates superior outcomes compared to the ATP mode, preserving short calculation times. The analysis is primarily focused on feasibility and preliminary evaluation, but the potential of this automated workflow to improve the clinical practice and the patient outcomes remains significant.
