Abstract: The invention describes a method of generating metabolic images of an investigation region (3) of a body (1) by irradiating an X-ray fluorescence marker in that region and detecting the resulting X-ray fluorescence with a fluorescence detector (30). A fan beam (12) is used as a source of primary X-radiation, thus allowing the scanning of a whole body slice (3) in one step. The fluorescence image may be directly measured, e.g. by mapping voxels (104) of the investigation region onto pixels (134) of the detector (130) with the help of a pinhole collimator (132), or it may be reconstructed by procedures of computed tomography. Moreover, a morphological image may be generated by simultaneously recording X-ray transmission through the body (1).

Abstract: A method of stress-optical force measurement where a linearly polarized light ray is guided into a stress-optical measurement array consisting of several measurement members on which the force to be measured acts in a distributed manner. The light ray successively traverses the measurement members while being influenced in a force-dependent manner and is applied to a subsequent evaluation unit for evaluation. The invention also relates to a measurement device for performing the method, comprising a measurement array and an evaluation unit between two plates which are arranged in parallel at a distance from one another. The measurement array consists of at least three spaced stress-optical measurement members which keep the plates at a distance from one another, influence the light ray in a force-dependent manner, and guide the light ray into the evaluation unit arranged between two measurement members.

Abstract: A method of transmitting at least two measured values by means of light pulses which are passed by an optical transmitter through an optical transmission path to an optical receiver and whose relative separation in time is proportional to the measured value. The energy consumption for the optical transmission of the measured values is reduced by transmitting needle pulses cyclically, one after another in the same order of succession, in that per measured value an optical measuring pulse is transmitted, whose separation in time from the optical measuring pulse associated with a preceding measured value is proportional the magnitude of the measured value, and in that for each group of measured values an optical identification pulse is transmitted, whose distance in time from a preceding measuring pulse is smaller than the smallest possible distance in time between two successive optical measuring pulses.

Abstract: The present invention relates to X-ray image acquisition technology in general. Employing phase-contrast imaging for X-ray image acquisition may significantly enhance the quality and information content of images acquired. However, phase-contrast information may only be obtainable in a small detector region, possibly being too small for a sufficient field of rotation view for specialized X-ray imaging applications. Accordingly, an apparatus for phase-contrast imaging is provided that may allow the acquisition of an enlarged field of view. According to the present invention an apparatus (1) for phase-contrast imaging is provided, comprising an X-ray source (2), an X-ray detector (12) element having a detector size, a beam splitter grating (8) and an analyzer grating (10). An object (6) is arrangeable between the X-ray source (2) and the X-ray detector (12). The beam splitter grating (8) and the analyzer grating (10) are arrangeable between the X-ray source (2) and the X-ray detector (12). X-ray source (2), the beam splitter grating (8), the analyzer grating (10) and the X-ray detector (12) are operatively coupled such that a phase-contrast image of the object (6) is obtainable. The apparatus (1) is adapted for acquiring a phase-contrast image having a field of view larger than the detector size. The X-ray detector element (12) is displaceable and by the displacement of the X-ray detector (12) a phase-contrast image of the field of view is obtainable.

Abstract: A sensor includes a pair of resiliently loaded jaws for receiving a finger, the sensor including a pair of fiber optic light transmitting guides secured in fixed spaced relation to one of the jaws for sensing blood in the finger tip. A control unit includes a light generator for transmitting light modulated at first and second frequencies to one of the guides via a light guide transfer section. The finger pulse modulates the received transmitted light. The modulated light is sensed by the other guide and returned to a receiver in the control unit via the transfer section for separating and demodulating the different frequency signals. The control unit includes a calculating unit which has two branches for processing and then combining by dividing the processed demodulated signals for determining the oxygen content of the blood from the relative magnitudes of the pulse-dependent modulation factor of the wave reflected from the finger.
