Novel imaging technique improved radiation dose mapping in cancer treatment, indicating enhanced accuracy using detection sensitivity adjustments.

Improved radiation dose mapping accuracy was achieved through detection sensitivity compensation techniques.
The study demonstrated a significant increase in the gamma index passing rate from 56.86% to 78.24% post-compensation.
Simulation and experimental results showed strong agreement for iRAI images, validating the detection sensitivity maps generated.
Addressing inhomogeneities in detection sensitivity resulted in a convergence of relative amplitudes toward 1 across various beam positions.

Huang et al. (2025) studied this question.
