Lesion Visibility in Low Dose Tomosynthesis
Visibility of lesions in mammography are significantly reduced by the presence of anatomical, or structure, noise. Breast tomosynthesis offers the possibility of reducing this noise. We have compared the detec...

The Dependence of Tomosynthesis Imaging Performance on the Number of Scan Projections
In general, the use of more projections results in fewer tomosynthesis reconstruction artifacts. However, under a fixed dose, an excess number of projections will make the detector noise more pronounced in eac...

Finding All Undercut-Free Parting Directions for Extrusions
For molding and casting processes, geometries that have undercut-free parting directions (UFPDs) are preferred for manufacturing. Identifying all UFPDs for arbitrary geometries at interactive speeds remains an...

The Effect of Tomosynthesis X-Ray Pulse Width on Measured Beam Quality
Tomosynthesis acquisition typically consists of a set of short x-ray pulses from an x-ray tube moved to different locations relative to the object being imaged. The pulsed x-rays used in the acquisition exhibi...

The Key-Dependent Attack on Block Ciphers
In this paper, we formalize an attack scheme using the key-dependent property, called key-dependent attack. In this attack, the intermediate value, whose distribution is key-dependent, is considered. The attac...

Improved Integral Attacks on MISTY1
We present several integral attacks on MISTY1 using the FO Relation. The FO Relation is a more precise form of the Sakurai-Zheng Property such that the functions in the FO Relation depend on 16-bit inputs instead...
