Image Segmentation with Directed Trees

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980
This correspondence presents a simple algorithm to detect and label homogeneous areas in an image, using directed trees for region labeling. The scheme constructs directed trees with the image points as nodes, guided by an edge value computed at every point. These directed trees segment the image into disjoint regions.

New Directions in Cardiac Imaging

Annals of Internal Medicine, 1985
Cardiac imaging is among the most commonly used diagnostic techniques in cardiovascular medicine. Conventional imaging modes (chest roentgenography, echocardiography, radionuclide imaging, and angiography) allow delineation of cardiac morphology, coronary anatomy, ventricular and valvular function, and cardiac shunts, and permit qualitative evaluation ...

Direct Imaging of Charge Modulation

Physical Review Letters, 1996
Electron diffraction calculation suggest that a modulation in the density of valence electrons may dominate the images of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} under certain experimental conditions. This prediction is supported by electron microscope experiments where we observe modulation that we attribute to charge transfer over a distance of

Future Directions in Imaging Neurodegeneration

Current Neurology and Neuroscience Reports, 2017
Neuroimaging comprises a powerful set of instruments to diagnose various neurodegenerative disorders, clarifies their neurobiology, and monitors their treatment. Magnetic resonance imaging depicts volume changes, as well as abnormalities in functional and structural connectivity.

Chemokine receptor – Directed imaging and therapy

Methods, 2017
The C-X-C chemokine receptor 4 (CXCR4) and its natural ligand CXCL12 are key factors in the process of cell migration, homing of hematopoietic stem cells to the bone marrow, and represent important mediators of angiogenesis and cell proliferation. The CXCR4/CXCL12 interplay can be disrupted by CXCR4 antagonists such as Plerixafor which are already in ...

Future Directions in Molecular Imaging

2004
After the identification of new genes, functional information is required to investigate the role of these genes in living organisms. This can be done by analysis of gene expression, protein—protein interaction, or biodistribution of new molecules and may result in new diagnostic and therapeutic procedures which include visualization of and ...
