Image reconstruction from limited Fourier data.

Accurate image reconstruction from few-view and limited-angle data in diffraction tomography.

We present a method for obtaining accurate image reconstruction from highly sparse data in diffraction tomography (DT). A practical need exists for reconstruction from few-view and limited-angle data, as this can greatly reduce required scan times in DT. Our method does this by minimizing the total variation (TV) of the estimated image, subject to the constraint that the Fourier transform of th...

Limited Angle Tomography of Sparse Images from Noisy Data using TLS MUSIC Algorithm

The limited angle tomography problem is to reconstruct an image from a set of its projections (Radon transform) over a limited range of angles. It has applications in medical imaging and synthetic aperture radar. From the Radon projectionslice theorem, this problem is equivalent to image reconstruction from partial Fourier data. This paper presents an algorithm for solving this problem for spar...

Ultra-Fast Image Reconstruction of Tomosynthesis Mammography Using GPU

Digital Breast Tomosynthesis (DBT) is a technology that creates three dimensional (3D) images of breast tissue. Tomosynthesis mammography detects lesions that are not detectable with other imaging systems. If image reconstruction time is in the order of seconds, we can use Tomosynthesis systems to perform Tomosynthesis-guided Interventional procedures. This research has been designed to study u...
