A High-Resolution Technique for Ultrasound Harmonic Imaging Using Sparse Representations in Gabor Frames
Gabor frames harmonic imaging sparse representations
2010/1/6
Over the last few decades there were dramatic
improvements in ultrasound imaging quality with the utilization
of harmonic frequencies induced by both tissue and echo-contrast
agents. The advantages...
Location proteomics - Building subcellular location trees from high resolution 3D fluorescence microscope images of randomly-tagged proteins
Location proteomics 3D fluorescence microscope images
2009/12/23
The overall object of proteomics is to characterize all of the proteins expressed in a given cell type. With the rapiddevelopment of random gene tagging technology and high resolution fluorescence mic...
Improved Image Fusion in PET/CT Using Hybrid Image Reconstruction and Super-Resolution
Improved Image Fusion PET/CT
2009/9/8
Purpose. To provide PET/CT image fusion with an improved PET resolution and better contrast ratios than standard reconstructions. Method. Using a super-resolution algorithm, several PET acquisitions w...
High Resolution Imaging of Cell Organelle Using Compact Polarization Mode Converter
compact polarization mode converter azimuthally polarized beam super resolution
2009/6/2
The shape of focal spot is affected by the distribution of polarization and phase on the cross-section of the incident beam. We demonstrated the spatial resolution enhancement effect using the differe...
