Breast ultrasound is a diagnostic tool available through breast imaging services at Mayo Clinic . FYI is a tool for integrating imaging , document management and workflow functionality into your workgroup or enterprise-wide solution . In medical imaging , MRI , CAT and PET modalities can be separately used to image the same tissue , providing complementary information for visualization and diagnosis . These photos may be obtained for use at the University of Virginia and may be used in GIS , CAD , and other imaging packages . PHASE II : Applying the basic scientific theory to field data , demonstrate feasibility of : 1 ) improved submarine detection in the presence of multiple , moving , interference sources in shallow water ( non-stationary , non-Gaussian interference ) by super resolution of interfering sources employing fusion of radar and sonar sensor data and the incorporation of environmental information at the level of coherent signal processing , or 2 ) improved acoustic synthetic aperture imaging of mines by super resolution of high level clutter in the presence of shallow water multipath , or 3 ) super resolution of Fourier Transform Infra Red ( FTIR ) absorption or transmission spectra for improved detection of chemical species by incorporating chemical bond characteristics as prior information , or 4 ) improved synthetic aperture radar that simultaneously reduces mainlobe width and sidelobe levels , rejects clutter , images non-point scatterers , reduces the effects of colored signal-independent background noise , and allows system operation with waveform diversity sufficient to mitigate jamming .
