Comparison of uncompressed volumetric breast data to compressed projection mammographic data poses a variety of challenges to accurately localize anatomy in both data sets. This work presents a method for simulating the mechanical compression of volumetric breast data. We use an approach based on a rectilinear-grid finite-element mesh and apply the method(More)
Quantum cascade laser (QCL) is a specific type of semiconductor laser that operates through principles of quantum mechanics. Because there is a genuine lack of compact and coherent devices which can operate in the far-infrared region the motivation exists for designing a terahertz (THz) QCL. To ensure operation in the THz region the device must conform to(More)
