3D Total Variation Minimization Filter for Breast Tomosynthesis Imaging
نویسندگان
چکیده
C li n ic a l The TV minimization filter was applied to the clinical slices after reconstruction. After a comprehensive study with λ values (equal for all slices) ranging from 10 to 200, the λ value which enables the greater minimization of TV was chosen and the resultant image is shown. Fig. 2. 3D TV values for phantom unfiltered and filtered data plotted as a function of λ values. Fig. 3. ASF, plotted as a function of distance from slice of interest, for unfiltered and filtered phantom data with λ=80 and variable λ over slices.

Digital breast tomosynthesis image reconstruction using 2D and 3D total variation minimization
BACKGROUND Digital breast tomosynthesis (DBT) is an emerging imaging modality which produces three-dimensional radiographic images of breast. DBT reconstructs tomographic images from a limited view angle, thus data acquired from DBT is not sufficient enough to reconstruct an exact image. It was proven that a sparse image from a highly undersampled data can be reconstructed via compressed sensin...
متن کاملUltra-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...
متن کاملAn Object-Oriented Simulator for 3D Digital Breast Tomosynthesis Imaging System
Digital breast tomosynthesis (DBT) is an innovative imaging modality that provides 3D reconstructed images of breast to detect the breast cancer. Projections obtained with an X-ray source moving in a limited angle interval are used to reconstruct 3D image of breast. Several reconstruction algorithms are available for DBT imaging. Filtered back projection algorithm has traditionally been used to...
متن کاملPractical iterative image reconstruction in digital breast tomosynthesis by non-convex TpV optimization
Digital breast tomosynthesis (DBT) is a rapidly developing imaging modality that gives some tomographic information for breast cancer screening. The effectiveness of standard mammography can be limited by the presence of overlapping structures in the breast. A DBT scan, consisting of a limited number of views covering a limited arc projecting the breast onto a fixed flat-panel detector, involve...
متن کاملAn iterative tomosynthesis reconstruction using total variation combined with non-local means filtering
BACKGROUND After the release of compressed sensing (CS) theory, reconstruction algorithms from sparse and incomplete data have shown great improvements in diminishing artifacts of missing data. Following this progress, both local and non-local regularization induced iterative reconstructions have been actively used in limited view angle imaging problems. METHODS In this study, a 3D iterative ...
