摘要： Multimodal nanoparticles are nanoparticles containing contrast agents for PAT and one or more of luminescence imaging, x-ray imaging, and/or MRI. The multimodal nanoparticles can have a dielectric core comprising an oxide with a metal coating on the core. The particles can be metal speckled. The multimodal nanoparticles can be used for therapeutic purposes such as ablation of tumors or by neutron capture in addition to use as contrast agents for imaging.

摘要： Embodiments of the invention pertain to methods for imaging a light absorption coefficient distribution. Embodiments of the subject method can be implemented without knowing the strength of incident light in advance and without requiring careful calibrations in the non-scattering medium. Embodiments of the method can combine conventional photoacoustic tomography (PAT) with diffusing light measurements coupled with an optimization procedure based on the photon diffusion equation. Images of absorbing targets as small as 0.5 mm in diameter embedded in a 50 mm diameter background medium can be quantitatively recovered. Small targets with various optical contrast levels relative to the background can be detected well. Embodiments of the subject reconstruction method can include first obtaining the map of absorbed optical energy density. Embodiments can obtain the map of absorbed optical energy density through a model-based reconstruction algorithm that is based on a finite element solution to the photoacoustic wave equation in frequency domain subject to the radiation or absorbing boundary conditions (BCs). The distribution of optical fluence can then be obtained. Embodiments can obtain the distribution of optical fluence using the photon diffusion equation based optimization procedure. The distribution of optical absorption coefficient can then be recovered from the distribution of optical fluence and the absorbed energy density.
