A lighting arrangement for a medical imaging system having a cylindrical wall that forms a tunnel that receives a patient to be scanned. The lighting arrangement includes a transparent wall section formed in the wall, wherein the transparent wall section extends along a transparent portion of a wall circumference. The imaging system also includes a lighting device located adjacent an outer surface of the transparent wall section. The lighting device extends along a device portion of a wall circumference corresponding to the transparent portion wherein light emitted by the lighting device is transmitted through the transparent wall section in a direction orthogonal to a longitudinal axis of the tunnel to circumferentially illuminate the tunnel. In addition, a system status is indicated by a color of light emitted by the LEDs. Further, light emitted by the lighting device varies in intensity to indicate a changing count rate.

Functional and anatomical information are combined in medical imaging. The functional information is treated as a light source illuminating surrounding anatomy, not just along a viewing direction. As a result, rendered images of the anatomy include highlighting or visual lighting queues showing locations of biological activity using global illumination.

The invention relates to a method and a device for determining the position of a part of a medical instrument with an x-ray sensitive sensor in a plane of an x-ray image using an x-ray facility having an x-ray beam source and a device, which is assigned to the beam source and influences the x-ray radiation emitted by the x-ray beam source, wherein a spatial region, in which the medical instrument is located, is scanned with x-ray radiation and at the same time x-ray radiation is detected with the x-ray-sensitive sensor with the device for influencing the x-ray radiation rotating at constant speed, the rotation being synchronized to the receipt of signals based on x-ray radiation with the x-ray-sensitive sensor and with the position of the part of the medical instrument in the plane of an x-ray image being determined based on the x-ray radiation detected with the x-ray-sensitive sensor.

A method for volume rendering a digitized medical image includes providing a digitized medical image volume comprising a plurality of intensities on a 3-dimensional grid of points, providing a projection plane comprising a 2-dimensional lattice of points onto which rendering rays are projected from a viewing point through the image volume, advancing a sampling point along a ray through the image volume, generating an incision region within the image volume, determining whether the sampling point is within the incision region, where a first transfer function is applied to a sample value interpolated from a first volume if the sampling point is within the incision region, and a second transfer function is applied to a sample value interpolated from a second volume if the sampling point is outside the incision region, and accumulating the output of the transfer function.

A method for implementing per-use licensing for image processing software includes acquiring image data from an image scanner. Processed image data is calculated from the image data using an image processing module. The processed image data is exported. The use of the image processing module is logged in an accounting database when the processed data are exported. Access to the accounting database is provided for account settlement.

To make optimum use of an x-ray image recording system with an x-ray C-arm, which has an x-ray radiation source and an x-ray detector and can be pivoted about any axis, 2D axis lines are plotted in two x-ray images of an object to be imaged more precisely and these 2D axis lines are used to define a 3D axis line and the x-ray image recording system is set so that it can be directly pivoted precisely about this 3D axis line. A sequence of x-ray images is then recorded in positions of the x-ray C-arm, between which the same can be pivoted about this defined axis. This displays the object optimally.
