Abstract: The invention relates to a device for reading out at least one especially flexible imaging plate. The readout device comprises a reader for reading out information stored on the imaging plate, and a transport device having at least one drive means for transporting the imaging plate relative to the reader along a guide means on the transport path. The shape of the transport path is adapted to the shape of a readout area of the reader. At least one substantially solid support for the imaging plate is provided. The shape and dimension of the support are adapted to the shape of the transport path. When the imaging plate is transported together with the support, the imaging plate does not come into contact with the drive means. The invention also relates to the support for the imaging plate.

Abstract: A method for reading out image information stored in a storage phosphor of a storage medium includes moving a light beam over the storage medium. A luminescence signal is generated by the photostimulation of the storage phosphor. In first time intervals a respective output value is determined from the luminescence signal, and a respective pixel value of an image pixel of a digital image is determined from the output value. The output value is thereby determined by addition of a plurality of measurement values of the luminescence signal which are detected in second time intervals lying within the first time interval. A corresponding apparatus for carrying out the method is described as well.

Abstract: The invention relates to a method and a device for evaluating fluorescence partial images representing the same object region, independently of stray light. Two partial images of the objects are produced in the red and in the green by a camera (10). A quotient image is produced in pixels from said two partial images, and the frequency of the occurrence of the image points having a pre-defined red/green ratio is determined for said quotient image. The mean values and the width are determined for the distribution curve obtained in this way. The two end variables of the distribution curve are used to calculate a threshold value. The quotient image is modified using said threshold value such that its contrast in relation to interesting details is increased.

Abstract: The invention relates to a coupling unit (24) for transmitting high-frequency mechanical vibrations from a vibration generator (12) onto a tool (34). Said coupling unit comprises in input part (22) and an output part (30) that are interconnected via two identical vibration bars (26, 28), said bars being off-set from each other. The bars may have the shape of quadrants to provide the output movement in a direction that forms an angle of 90° with the direction of the input movement.

A housing is provided with an entrance window, through which an observation light returning from an examination area shines in, which is subsequently conducted to the image converter by the optical elements. The camera has a head part and a handle part, which are detachably connected to one another. The handle part can be adjusted to a wide variety of purposes when combined with different head parts.

Abstract: The invention relates to a method for improving the perceptibility of different structures on radiographs by means of an image processing device consisting a) in storing a radiograph in electronic form as a local space-intensity distribution, b) in carrying out a Fourier transformation for determining a frequency-intensity distribution, c) in filtering said frequency-intensity distribution by modifying weighting between the high-frequency and low-frequency image signal components, wherein the fixing of the image signal components to be more intensively weighted is carried out taking into account the mean structure size of said structures whose perceptibility is to be improved, d) in carrying out an inverse Fourier transformation of the filtered frequency-intensity distribution in order to obtain a modified space-intensity distribution in which said structures are more easily perceptible.

Abstract: In order to set up digital image acquisition in classic panoramic X-ray machines, the invention proposes providing a row of detectors in the cartridge unit of the machines, said row of detectors being arranged or being able to be arranged behind the recording slit. The output signals from the row of detectors and the output signals from a rotary encoder are wirelessly transferred to an evaluation unit. Retrofitting the digital image acquisition thus does not require any intervention in safety-related parts of the panoramic X-ray machine.

The working fluid jet contains sharp-edged small abrasive particles suspended in a fast carrier air flow. The spray jet has small water droplets. The working material jet and the spray jet are emitted by spatially separated delivery nozzles. The spray jet thus does not reach to the working jet delivery nozzle.
