    摘要: A method for monitoring the X-ray dosage administered to a patient by a radiation source when using an X-ray device is proposed. The X-ray device is in particular a C-arm X-ray device. A location-dependent dosage value on the surface of the patient is determined with reference to parameters which describe the recording geometry and the radiation that is administered. The surface is described by a patient model in particular. A representation of the dosage value and/or of a value derived therefrom is displayed.

    摘要: An image processing system and method to resize image data from two sources of image data. The method includes receiving a first matrix of image data from a first detector and a second matrix of image data from a second detector. Detector-specific image correction is performed on the first matrix data and the second matrix data independently. The first matrix and the second matrix are re-mapped into virtual matrices of a common size, which are processed through a common image pipeline. The virtual matrices are remapped into different matrix sizes for further processing or display.

    摘要: A large-area CMOS flat X-ray detector is disclosed. The detector includes a plurality of CMOS detector chips, mounted on a substrate with a butt joint. Two alternative embodiments of the CMOS detector chips are described. In the first embodiment, drive elements and read elements are provided on two of four edges of the chip. If the connecting lines are routed to the first edge, this allows an embodiment in which more than four such CMOS detector chips are fitted alongside one another. In one alternative embodiment, all the drives and read operations can be carried out from a first edge so that at least six such CMOS detector chips can be adhesively bonded on the substrate alongside one another.

    摘要: A system and method enhance the visibility of medical devices shown in internal images. A medical device may be inserted into a patient. Internal images of the patient may then be acquired via various medical imaging techniques. However, the medical device may only be partially visible in the images, if at all. For instance, the images may be acquired with minimal radiation exposure to the patient and/or the medical device may be thin or made of translucent material. Model data may be associated with the geometry or other characteristics of the medical device. The model data may be adapted, such as rotated, resized, bent, or otherwise modified, to form a “best fit” with the medical device as actually shown in the internal images. The adapted model data may be superimposed onto a display of the medical device as shown in the internal images to enhance visibility of the medical device.

    摘要: A system and method to reduce bright burn in images, such as x-ray images. The reduction of bright burn may be accomplished by processing a received raw image to obtain a grey-value histogram. The raw image may be divided into a plurality of regions of interest, and an average signal of each region of interest is calculated. Regions of interest are identified as bright burn candidates based on a predetermined function of the average signal of each region of interest and the grey-value histogram of the entire raw image. The regions of interest may be analyzed for local connectivity to estimate bright burn areas. An image with reduced bright burn is generated by either automatically adjusting a physical wedge filter position based on the bright burn areas, or by adaptively reducing a signal level of the bright burn areas.

    摘要: A system and method in which image processing parameters that are used globally or which change locally within the image are adapted to improve image quality by using the acquisition parameters, image analysis data, and calibration/model data. Image processing parameters are established as a function of the acquisition parameters. The acquisition parameters include one or more of an x-ray tube voltage, a pre-filtration, a focal spot size, an x-ray source to detector distance (SID), and a detector readout mode. Image processing parameters may also be established as a function of local or global image analysis, such as signal-to-noise ratio, as well as a function of predicted signal-to-noise ratio determined from the calibration data and a predetermined model.
