Method for assisting with percutaneous interventions

The present invention relates to a method for assisting with percutaneous interventions, wherein 2D x-ray images of an object region are recorded before the intervention using a C-arm x-ray system or a robot-based x-ray system at different projection angles and 3D x-ray image data of the object region is reconstructed from the 2D x-ray recordings. One or more 2D or 3D ultrasound images are recorded before and / or during the intervention using an external ultrasound system and registered with the 3D image data. The 2D or 3D ultrasound images are then overlaid with the 3D image data record or a target region segmented therefrom or displayed next to one another in the same perspective. The method allows a puncture or biopsy to be monitored with a low level of radiation.

Circuit and channel assignment plan for optical transmissions

To support interleaving of optical channels and to provide sufficient isolation between such interleaved channels, a circulator (60-62) receives, on an optical fiber (16-18), a broadband signal containing a plurality of adjacent channels. The circulator selectively routes the broadband signal through a filter (64, 66) to isolate, on an individual basis, at least one desired channel. A filtered signal, corresponding to the at least one desired channel, is then output from the filter (64-66) and reflected back into the filter by a mirror (68-70) such that the at least one desired channel is subjected to a second filtering process that further improves isolation of the at least one desired channel. Following this second filtering process, the at least one desired channel is applied to the circulator (60-62) for re-inserting into the optical fiber (16-18), as illustrated in FIG. 6. To mitigate the effects of four-wave mixing in each bidirectional optical fiber, a channel assignment plan ensures that pairs of adjacent channels are assigned on a mutually exclusive basis to at least one of an up-link and a down-link direction.
