Kinetic assessment of breast tumors using high spatial resolution signal enhancement ratio (SER) imaging

High Resolution T2 Breast Imaging using FADE

Introduction High-resolution 3D imaging is useful for improving the specificity of breast MRI since morphological characteristics, such as spiculations and heterogeneity, vary with histology [1]. The specificity of breast MRI can be further improved by considering physiological information such as diffusion [2]. Unlike T1-weighted contrast-enhanced imaging, it is difficult to acquire high-resol...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Signal enhancement and Patterson-search phasing for high-spatial-resolution coherent X-ray diffraction imaging of biological objects

In this decade coherent X-ray diffraction imaging has been demonstrated to reveal internal structures of whole biological cells and organelles. However, the spatial resolution is limited to several tens of nanometers due to the poor scattering power of biological samples. The challenge is to recover correct phase information from experimental diffraction patterns that have a low signal-to-noise...

High-resolution retinal imaging: enhancement techniques

AO has achieved success in a range of applications in ophthalmology where microstructures need to be identified, counted, and mapped. Multiple images are averaged to improve the SNR or analyzed for temporal dynamics. For small patches, image registration by cross-correlation is straightforward. Larger images require more sophisticated registration techniques. Strip-based registration has been u...
