  Currently, diagnostic medicine uses a multitude of tools ranging from
ionising radiation to histology analysis. With advances in piezoelectric
crystal technology, high-frequency ultrasound imaging has developed to achieve
comparatively high resolution without the drawbacks of ionising radiation. This
research proposes a low-cost, non-invasive and real-time protocol for informing
photo-therapy procedures using ultrasound imaging. We combine currently
available ultrasound procedures with Monte Carlo methods for assessing light
transport and photo-energy deposition in the tissue. The measurements from
high-resolution ultrasound scans is used as input for optical simulations.
Consequently, this provides a pipeline that will inform medical practitioners
for better therapy strategy planning. While validating known inferences of
light transport through biological tissue, our results highlight the range of
information such as temporal monitoring and energy deposition at varying
depths. This process also retains the flexibility of testing various
wavelengths for individual-specific geometries and anatomy.
