13. Caracterização de um sistema imageador infravermelho termal através de suas resoluções espacial e radiométrica / Characterization of a thermal infrared line scanner trough its spatial and radiometric resolutions
The thermal infrared spectral bands in airborne sensors are still little explored in Brazil. The Institute of Advanced Studies (IEAv) at the Aerospace Technical Center (CTA) developed the Thermal Infrared Imaging System (SISIMI), an aerial surveillance prototype sensor operating in the 8 to 12.5 um band with a rotating imaging scanner of 720 lines/s. The obj

14. Frequency-domain techniques enhance optical mammography: Initial clinical results
We present a novel approach to optical mammography and initial clinical results. We have designed and developed a frequency-domain (110-MHz) optical scanner that performs a transillumination raster scan of the female breast in approximately 3 min. The probing light is a dual-wavelength (690 and 810 nm, 10-mW average power), 2-mm-diameter laser beam, and the

15. Automated sequence reading and analysis.
We report on a system developed by Bio-Rad Laboratories, Inc. which combines automated reading of DNA sequencing autoradiograms with comprehensive software for shotgun overlapping of the readings, analysis of the sequences derived and searching of databases. Reading is accomplished using a high speed optical scanner and pattern recognition software operating

16. Ultrahigh-resolution multicolor colocalization of single fluorescent probes
An optical ruler based on ultrahigh-resolution colocalization of single fluorescent probes is described in this paper. It relies on the use of two unique families of fluorophores, namely energy-transfer fluorescent beads (TransFluoSpheres) and semiconductor nanocrystal quantum dots, that can be excited by a single laser wavelength but emit at different wavel

17. Positron emission tomography provides molecular imaging of biological processes
Diseases are biological processes, and molecular imaging with positron emission tomography (PET) is sensitive to and informative of these processes. This is illustrated by detection of biological abnormalities in neurological disorders with no computed tomography or MRI anatomic changes, as well as even before symptoms are expressed. PET whole body imaging i
