Comparison of dIMMI and CDMMI models. The dIMMI model has statistically superior performance in accurately modelling the photoacoustic imaging process for low image resolutions (a, b) under both the L₁ and L₂ norms. At high resolutions, CDMMI trended towards superior performance over dIMMI, though does not consistently achieve statistical separation. (c) Both dIMMI and CDMMI have improved SSIM scores as a function of pixel resolution; CDMMI achieves slightly better performance at high resolutions.
