A method is disclosed for displaying a tissue containing a fluorescent dye at least in sections. In order to reduce interference signals, it is proposed to record a first fluorescent image during an illumination phase, and a second fluorescent image during a dark phase, and to correct the first fluorescent image by subtracting the second fluorescent image and to process it subsequently to form an overall image.

An apparatus is disclosed for recording a tissue containing a fluorescent dye at least in sections. The apparatus includes an illumination device for illuminating the tissue; a first light, suitable for exciting the fluorescent dye; and an image acquisition device. To generate first light with a particularly high light intensity, the illumination device and the image acquisition device are accommodated in separate components.

The measurement of the width of a pattern on a semiconductor wafer or a flat panel is carried out in an optical microscope or a scanning electron microscope in a number of measuring steps, By a computing rule, the quality of the correlation between the measured data obtained in the individual measurement steps, as well as reference data taken from the design, the value for the parameter is calculated and compared with a limiting value obtained from experience. In the event of violation of the limiting value, a signal is generated and the further processing of the object is interrupted.

A method for operating a magnetic resonance facility is proposed. The magnetic resonance facility has a number of power-consuming components. The power consumption is determined for each component. Operation of the components is controlled based on at least one criterion so that a predetermined threshold value for the overall power consumption of the magnetic resonance facility is not exceeded.

The present invention relates to an improved process for producing a biodegradable and/or absorbable silica sol material which is advantageous especially with regard to the reproducibility of the material, the rapidity of the synthesis and the possibility of being able to produce the silica sol material on an industrial scale. A further subject matter of the invention relates to a biodegradable and/or absorbable silica sol material which can be produced by the synthesis process according to the invention.
摘要:
In a method for determining the ventilation of a lung of an object under examination by magnetic resonance imaging, at least two first lung-representing image data sets are acquired at different intervals of the breathing phase. The density change of the lung tissue is automatically determined from the signal difference between the image signals of the first image data sets in at least one corresponding region of the first lung-representing image data set. The lung or the thorax volume is automatically determined using at least two of the first image data sets, or using at least an additional second lung-representing image data set in a breathing phase that corresponds with the breathing phase of a first image data set. The localized, quantitative ventilation of the lung is automatically calculated depending on the density change of the lung tissue and the change of the lung or thorax volume.

The invention relates to a device for producing processed cheese portions, comprising a plurality of modules that are arranged successively in the direction of production, in which the processed cheese is formed into a band, cooled, and divided into portions, wherein the modules define a production space through which the processed cheese travels during the production of the processed cheese portions. The production space is enclosed by a spray-proof casing, wherein the casing comprises a frame structure and a plurality of sheet metal elements which are detachably connected to the frame structure, and wherein a sealing hose is arranged between a sheet metal element and the area of the frame structure opposite thereto, and encircles the sheet metal element or the area of the frame structure opposite thereto.
