- AJR. American journal of roentgenology
- 1 December 1983
The choice of the strength of the magnetic field for an imaging system based on the nuclear magnetic resonance of hydrogen is considered. It is shown by an analysis based on in vitro data that the… Expand
The role of thermal and fission neutrons in reactor neutron-induced upsets in commercial SRAMs
- P. Griffin, T. F. Luera, +4 authors E. Fuller
- Materials Science
- 1 December 1997
Reactor neutron environments can be used to test/screen the sensitivity of unhardened commercial SRAMs to low-LET neutron-induced upset. Tests indicate both thermal/epithermal (<1 keV) and fast… Expand

Technical Alternatives In Nuclear Magnetic Resonance (NMR) Imaging
- H. Hart, P. Bottomley, +7 authors D. Vatis
- Engineering
- Other Conferences
- 13 December 1983
In this paper we consider the choice of the magnetic field for an imaging system based on the nuclear magnetic resonance of hydrogen. We show by analysis that the quality, or contrast-to-noise ratio,… Expand
Transducer system for the noninvasive recording of arterial pressure contours
- S. Karr, T. Karwoski, J. Jacobs, L. Mockros
- Materials Science, Medicine
- Annals of Biomedical Engineering
- 2006
A transducer system is described that permits noninvasive recordings of the pressure-vs-time arterial profile at any palpable site on the body. A thin (30 μm) piezoelectric polymer film of… Expand

Method and apparatus for coherent imaging system
- M. O’Donnell, B. Kenneth, C. Crawford, N. Pelc, S. Karr
- Physics
- 1 May 1994
A method and apparatus for improved digital processing of the analog echo signals in a coherent imaging system is described which simplifies the channel circuitry requirements. The analog echo… Expand
Application of reactors for testing neutron-induced upsets in commercial SRAMs
- P. Griffin, T. F. Luera, +4 authors E. Fuller

- 1 August 1997
Reactor neutron environments can be used to test/screen the sensitivity of unhardened commercial SRAMs to low-LET neutron-induced upset. Tests indicate both thermal/epithermal (< 1 keV) and fast… Expand
Architecture for ultrasonic imaging
- B. Kenneth, S. E. Noujaim, T. Vogelsong, S. Karr
- Physics
- 3 January 1989
An ultrasonic imaging processing system includes transducers and means to generate in an analog fashion, in-phase and quadrature phase signals. These signals are converted to digital form and a… Expand
