    Presents several biological applications of near field optical microscopy, in combination with force microscopy. Aperture near field scanning optical microscopy (NSOM) with fluorescence detection gives (bio)chemical specificity and orientational information, in addition to the simultaneously acquired force image. This technique has large potential for DNA sequencing, molecular organization in mono... View full abstract»

    The vitality of dental pulp is for important routine diagnosis and for treatment of tooth inflammation and necrosis. To determine the pulp vitality of a tooth, many techniques have been adopted by clinicians, such as radiographic examination, tooth plethysmography, and electric pulp testing (EPT). With regard to cost, effectiveness, and degrees of invasiveness, EPT has become the most useful and i... View full abstract»

  • Japan's commercial development of the electron microscope

    Publication Year: 1996, Page(s):31 - 34

    Americans have a picture of Japan as a country which, in the years after the Second World War, was able to produce only inexpensive and shoddy goods. This picture is not, however, entirely accurate. For example, the first electronic product exported from Japan to America after the war was not, as most suppose, the transistor radio but a highly complex research tool, the electron microscope. Today,... View full abstract»

    The images used in this research were digitized from 35mm color photographic slides obtained from a private dermatology practice and from New York University. The authors compared 6 color segmentation methods and their effectiveness as part of an overall border-finding algorithm. The PCT/median cut and adaptive thresholding algorithms provided the lowest average error and show the most promise for... View full abstract»

  • Engineering and the law. Public policy and the preemption of state tort claims against medical device manufacturers

    As the settlement of breast implant cases illustrate, the dynamics of the tort system are such that safe products can still be driven from the market by emotional pleas to juries. Given the importance of medical devices in modern medicine, it is critical that the legal system limit tort claims against medical device manufacturers. While it may ultimately be necessary for Congress to create a statu... View full abstract»

    Fluorescence in situ hybridization (FISH) is a rapidly expanding imaging technique in medical research and clinical diagnosis. Both researchers and clinicians find it helpful to employ quantitative digital imaging techniques with FISH images. This technique is of particular interest for multi-probe mixtures and for the automated analysis of large numbers of specimens. In the preparation of FISH sp... View full abstract»

  • Coherent methods in confocal microscopy

    Publication Year: 1996, Page(s):84 - 91

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1116 KB)

    The authors review the use of 2 kinds of coherent imaging methods in confocal microscopy: interferometry and the use of optical fibres. In both cases, the emphasis is concerned with detecting both the confocal field amplitude and its phase. It is usual in confocal systems to detect only the image intensity and so to loose all phase information. In order to detect the phase with an incoherent photo... View full abstract»

    Recording the electrical activity of the exposed brain, known as an electrocorticogram (ECoG), has had a long history. Multichannel recordings from the exposed brain cortex of conscious human patients as a diagnostic procedure to localize epileptic foci began in the early 1940s. Two centers, one at McGill University and the other at Harvard University launched this new field. Relatively unrecogniz... View full abstract»

    A preliminary study of coronary artery wall topography and mechanical properties is presented. The aim of this study was to give a brief demonstration of scanning acoustic microscopy (SAM) as a sonographic technique, and to apply the time-resolved SAM (TR-SAM) technique for quantification of coronary artery wall mechanical properties under passive conditions ex-vivo, and compare the data for the t...

    While light microscopy is almost 400 years old, developments of the past decade have offered a variety of new mechanisms for examination of biological and material samples. These developments include exploitation of techniques such as confocal microscopy, scanning near field microscopy, standing wave microscopy, fluorescence lifetime microscopy, and two-photon microscopy. In biology, advances in m... View full abstract»

    The authors have compared the performance of the EM-MLE and ICTM restorations applied to confocal images. Both methods greatly reduce diffraction-induced distortions of confocal images. Due to their nonlinearity, both are able (partially) to restore data of missing frequencies. From the authors' experiments, it is clear that for their test objects, the EM-MLE algorithm performs much better than IC... View full abstract»

    Cellular structures are made up of a very interesting puzzle of components, whose changes in molecular distribution are believed to underlie a wide range of cellular functions. For example, the cell cycle of mammalian cells is characterised by a series of ordered biochemical events. The availability of several specific probes has led to a renewed interest in optical microscopy as a very powerful t... View full abstract»

    The scanning laser acoustic microscopy (SLAM) technique offers high resolution for determining the properties of individual layers. To introduce the SLAM technique as a method for measuring the speed of sound in tubular layered organs, and possibly distinguish between the layers by this measure, the authors chose the guinea-pig urethra, due to its relatively simple layered structure. To obtain mor... View full abstract»

  • Scanning tunneling microscopy of DNA

    The systematic removal or destruction of DNA by the scanning tunneling microscope (STM) stems from the low conductivity of the molecule. Imaging DNA at exceedingly low currents and high voltages prevents damaging contact in humid conditions. The STM images of DNA on mica are evidence that the STM could be used to study genomic structure on a nanometer scale. Thus, the STM may join the scanning for... View full abstract»
