Applied Radiation and Isotopes, 2000
Any technique that can detect nitrogen concentrations can screen for concealed explosives. However, such a technique would have to be insensitive to metal, both encasing and incidental. If images of the nitrogen concentrations could be captured, then, since form follows function, a robust screening technology could be developed.

Imaging Goal-Directed Movement
Research Quarterly for Exercise and Sport, 1995The main purpose of the present investigation was to determine how Shepard's (1968) second-order isomorphic principle relates to imaging goal-directed movement. Reports of movement times for actual and imaged movements were obtained using Fitts-type tapping tasks.

Direct digital mammography image acquisition
European Radiology, 1997Mammography is a branch of radiology which could benefit greatly from the assimilation of digital imaging technologies. Computerized enhancement techniques could be used to ensure optimum presentation of all clinical images. Beyond this it will facilitate powerful new clinical resources such as computer-assisted diagnosis, tele-mammography, plus ...

Image-Directed Tumor Resection
Neurosurgery Clinics of North America, 1990Intra-axial tumors can be localized by intraoperative real-time ultrasound, stereotactic computed tomography (CT), or magnetic resonance imaging (MRI). In the former, intraoperative ultrasound can help a surgeon find a tumor and assess the completeness of resection.

Immune-Directed Molecular Imaging Biomarkers
Seminars in Nuclear Medicine, 2020Imaging has played a critical role in the management of patients with cancer. Novel therapies are emerging rapidly; however, they are effective only in some patients. With the advent of new targeted therapeutics and immunotherapy, the limitations of conventional imaging methods are becoming more evident.

If f: X → Y is a holomorphic map between complex spaces X and Y, the direct images f (q)(S) of a coherent O X -sheaf S in general are not coherent O Y -sheaves. For example if Y is just a single (reduced) point, coherence of the q-th image sheaf f(q)(S) means that f (q) (S)=H q (X, S) is a finite dimensional complex vector space.

Image Segmentation with Directed Trees
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980This 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, 1985Cardiac 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, 1996Electron 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, 2017Neuroimaging 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.
