Photoacoustic (PA) tomography (PAT) is a rapidly developing imaging modality that can provide high contrast and spatial-resolution images of light-absorption distribution in tissue. However, reconstruction of the absorption distribution is affected by nonuniform light fluence. This paper introduces a reconstruction method for reducing amplification of noise and artifacts in low-fluence regions. In...
Photoacoustic (PA) tomography is a rapidly developing imaging modality that provides high-contrast, high spatial-resolution images for vessel distributions in tissue. It can be applied to early breast cancer detection, and therefore it will be a valuable method for breast cancer diagnosis. Tissue absorbs and scatters light, and the optical fluence is known to approximately decrease exponentially....
