An Anthropomorphic Software Breast Phantom for Tomosynthesis Simulation: Power Spectrum Analysis of Phantom Projections

Description and Characterization of a Novel Method for Partial Volume Simulation in Software Breast Phantoms

“…Note that this approach does not require knowledge of true values of at each voxel nor the availability of distribution . From (17) follows: (26) which due to (A5) in the Appendix B reduces to: (27) By substituting and , (A7) and (27), into rightmost part of (A4) and solving for , we obtain:…”

“…The software anthropomorphic phantoms developed at the University of Pennsylvania have been used in various applications, including the validation and optimization of digital breast tomosynthesis (DBT) reconstruction methods [18]- [20], DBT image denoising methods [21], [22], ultrasound tomography (UST) reconstruction and segmentation methods [23], [24], analysis of power spectra descriptors in simulated phantom DBT images [10], [25], [26], analysis of texture properties in phantom digital mammography (DM) and DBT images [27], [28], and analysis of tumor detectability in DBT [29]- [31]. Physical versions of the 3D anthropomorphic software phantom have also been produced [32]- [36].…”

Anatomical complexity in breast parenchyma and its implications for optimal breast imaging strategies

“…15,17 This metric has subsequently been used by a number of investigators for the analysis of mammograms. 14,16,[18][19][20]…”

Development and characterization of an anthropomorphic breast software phantom based upon region-growing algorithm

“…Simulated images exhibited a range of beta exponent values comparable with clinical data. 56 psychophysical studies; synthetic images generated with our phantom have been also used in an ongoing observer study of tumor visibility in DBT. 59 (iv) Development of physical phantoms for the purpose of rapid prototyping.…”
