Diffuse optical tomography (DOT) is in an attempt to image the interior of human tissues. However, the NIR imaging suffers from low resolution due to the diffusive nature of the scattered light, which results into poor reconstructed image quality. Thus, the effort to improve the image quality remains in progress. The numerical simulation using high-pass filtering incorporated into the finite-element-based diffusion equation to reconstruct tomographic images of optical properties was performed where results reveal that several inclusions (tumors) can be well defined separately, thereby demonstrating the ability to highly resolve the image of interest with the optimal high-pass filtering process.
