Conclusion: As shown through simulations, the detector demonstrated satisfactory performance for applications in FLASH 3D dosimetry, with a mean discrepancy below 0.01 a.u. and the largest deviations observed at the edges. Although some artifacts appeared in the reconstructed image due to the limited number of projections, the overall results are promising. Further experimental tests are planned in the coming months for comprehensive characterization and validation of the reconstruction algorithm using experimental data.
