It is suggested that ultrasound data acquisition will play an increasing role in the future of medical imaging. Unlike magnetic resonance imaging (MRI) and computerized tomography (CT), ultrasound offers interactive visualization of underlying anatomy in real time. Additionally, ultrasound equipment costs far less and does not use ionizing radiation or(More)
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)
Fractal and non-fractal theories predict universal designs for biological branching transport networks whereby energy dissipation is minimized. However, they are inadequate to account for adaptation via designs that appear sub-optimal. Therefore we have evaluated another theory in the developing lung which is based on bifurcation design and the principle of(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)
