2D Numerical Mouse Phantom for Dynamic Photoacoustic Tomography Studies
Resource Type: Data
This dataset provides anatomically realistic spatiotemporal maps of optical absorption coefficient and photoacoustically induced pressure distribution for virtual imaging studies of dynamic photoacoustic tomography of small animal models. The anatomical information of the spatiotemporal object is derived from a two-dimensional (2D) cardio-torso slice extracted from the MOBY phantom. Each organ/tissue was assigned a plausible value of the optical absorption coefficient in the near-infrared range. The optical scattering coefficient was then assumed to be constant throughout the object. For each time frame, the photoacoustically induced pressure distribution was simulated by solving the diffusion approximation to the radiative transport equations with uniform illumination.
