Transcranial ultrasound localization microscopy (t-ULM) is faced with challenges posed by the skull, including acoustic attenuation and phase aberrations. There is a significant request for an efficient aberration correction method achieving a great balance between computational complexity and accuracy. In this study, the ray theory is first applied to in-vivo transcranial imaging to calculate the traveltime table in the inhomogeneous medium model of the imaging region.

Longer, more severe wildfire seasons are becoming the norm in fire-prone areas. Prescribed burning is a tool used to mitigate wildfire spread. However, prescribed burning also contributes to air pollution, including PM (particulate matter with aerodynamic diameter <= 2.

In this work we study the effect of the matrix of the source on the spectrum and on the full energy peak efficiency for low energy photons. Using realistic simulations carried out with PENELOPE 2018, including detector resolution, we show that small angle Compton scattering does contribute to the peak count rate, implying the dependence of the matrix effects on the linear attenuation coefficient μ and also on the scattering cross section. We show that the effect of Compton scattering can be removed from the apparent peak, resulting a "clean" peak depending only on μ.
