متن کاملInvestigating the Potential for Super-Resolution in Digital Breast Tomosynthesis
Digital breast tomosynthesis (DBT) is an emerging 3D x-ray imaging modality in which tomographic sections of the breast are generated from a limited range of tube angles. Because non-normal x-ray incidence causes the image of an object to be translated in sub-pixel increments with increasing projection angle, it is demonstrated in this work that DBT is capable of super-resolution (i.e., sub-pix...
متن کاملAnisotropic imaging performance in breast tomosynthesis.
We describe the anisotropy in imaging performance caused by oblique x-ray incidence in indirect detectors for breast tomosynthesis based on columnar scintillator screens. We use MANTIS, a freely available combined x-ray, electron, and optical Monte Carlo transport package which models the indirect detection processes in columnar screens, interaction by interaction. The code has been previously ...
متن کامل3D Total Variation Minimization Filter for Breast Tomosynthesis Imaging
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...
متن کاملDevelopment of an Analytic Breast Phantom for Quantitative Comparison of Reconstruction Algorithms for Digital Breast Tomosynthesis
Digital breast tomosynthesis (DBT) is an emerging modality for breast imaging. A typical tomosynthesis image is reconstructed from projection data acquired at a limited number of views over a limited angular range. In general, the quantitative accuracy of the image can be significantly compromised by severe artifacts and non-isotropic resolution resulting from the incomplete data. Nevertheless,...
