    摘要: In a modular solid state detector of the type including a scintillator and diodes for converting x-ray flux to a measurable electrical signal, the diodes are mounted out of the path of incident x-radiation to minimize noise and to limit degradation. The resulting configuration reduces efficiency because the active diode area is limited and the length of the light path between the scintillator and diode is increased. In order to compensate for that reduction in efficiency, optical potting material is used to join the scintillator to the diodes in order to minimize light attenuation between those elements. In addition, the outer surface of the cured optical potting material is coated with a thin specular layer of silver to keep the light within the optical potting material and thus most efficiently reflected from the scintillator to the diode.

    摘要: A modular solid-state detector cell which intimately associates a scintillator body with a pair of photoresponsive semiconductors so as to present on a single collimator plate all of the elements necessary for transforming incident X-radiation into a measurable electrical signal. The detector is provided with a precision slotted mounting arrangement for receiving the unit cells, and the cells when positioned within the detector assembly have the photoresponsive semiconductors enclosed within the light tight cell. The unit is adaptable to off-line testing of the separate cells for screening before assembly.

    摘要: A method for increasing the permeability of the stratum corneum by means of a source of light, preferably a laser, more preferably a pulsed laser. By increasing the permeability of the stratum corneum, access to the interstitial fluid is achieved, thereby enabling measurement of analytes in the interstitial fluid. In one aspect, the method comprises the steps of: (a) providing a source of light having a wavelength of from about 930 nm to about 1040 nm; and (b) exposing a region of the stratum corneum of the patient to said source of light for a period of time sufficient to form an opening in the stratum corneum. Preferably, exposure of the region of the stratum corneum to the source of light is ceased when an amount of interstitial fluid fills the opening in the stratum corneum, which amount is sufficient to cause the scatter intensity of the light reflected from the surface of the interstitial fluid occupying the opening in the stratum corneum to differ from the scatter intensity of the light reflected from a region of the stratum corneum that is substantially free of interstitial fluid. The invention also involves an apparatus for carrying out the foregoing method.

    摘要: An article capable of both collecting interstitial fluid and detecting an analyte in that fluid and a method for use of that article. Preferably, the article is also capable of measuring the amount of analyte in the interstitial fluid. The article can be used in conjunction with a meter that contains an appropriate detection element for determining the amount of analyte in the interstitial fluid. In one preferred embodiment, the article is a multiple-layer element comprising: (1) a layer that is capable of being placed in contact with the skin of a patient; (2) a layer that is coated over the skin-contacting layer; (3) a layer, substantially coplanar with the overcoat layer, that is capable of transporting interstitial fluid by means of chemically aided wicking; (4) a layer, overlying the interstitial fluid transporting layer, that is capable of being placed in contact with a meter, said layer having an opening therein through which light can be transmitted; (5) a layer, disposed on the surface of the meter-contacting layer that faces the skin-contyacting layer, that is capable of detecting the presence of analyte or measuring the amount of analyte in the fluid. In order to use the multiple-layer element, light from a source of light is transmitted through the opening in the multiple-layer material to be absorbed at a light-absorbing target on the skin-contacting layer. This light transfers energy to the target, and this transferred energy causes an opening to form in the skin-contacting layer and an opening to form in the stratum corneum. Interstitial fluid exudes from the opening in the stratum corneum and contacts the interstitial fluid transporting layer. The interstitial fluid then moves along or through the interstitial fluid transporting layer to the detecting layer.
