MEDICAL IMAGING SYSTEM AND METHOD FOR OPERATING A MEDICAL IMAGING SYSTEM
The invention relates to a medical imaging system, in particular for multispectral imaging, and a method for operating such an imaging system. The imaging system (100) comprises: a light source (110), which is designed to irradiate an object (10) with light of different wavelengths, according to a current wavelength spectrum of a plurality of possible wavelength spectra of the light source (110), wherein the light source (110) is assigned an individual identification code, IIC; a first memory (111), which is designed to store the individual identification code, IIC, of the light source (110); a second memory (112), which is designed to store spectrum information concerning possible wavelength spectra of the light source (110); a camera (130), which is designed to generate image data of the object (10) with light reflected or emitted from the object (10), based on the light according to the current wavelength spectrum; and, a controller (140), which is designed to adapt the generation of the image data by the camera (130) using the individual identification code, IIC, of the light source (110) and the spectrum information.

Abrégé
Guided percutaneous uncertainty mapping device and method for providing visual representations of an uncertainty map with respect to an organ during a guided percutaneous procedure using an electromagnetic tracking (EMT) system comprising an EMT field generator and tracker, a catheter with a EMT sensor for placing in the organ to mark a percutaneous procedure target, and a needle with an EMT sensor and an electronic data processor configured for carrying out the steps of: receiving an indication of a percutaneous procedure target; receiving three-dimensional (3D) positions and orientations of the catheter and the needle tracked in real-time from the EMT system; estimating the uncertainty of the received position and orientation of the needle; estimating the uncertainty of the received position and orientation of the catheter: estimating a trajectory uncertainty of the needle departing from a current position and orientation of the needle; generating a visual representation of the estimated trajectory uncertainty and catheter uncertainty with respect to the EMT coordinate system for displaying on a user interface.

SURGICAL INSTRUMENT AND STEERING MECHANISM FOR SAME
The disclosure relates to a steering mechanism for a surgical instrument. The steering mechanism has two motorized drives and is designed to spatially align a swash plate over the control angle of the two drives, said swash plate being designed to control a distal bending mechanism of the surgical instrument. A first drive of the two drives has a first motor which drives a worm shaft that drives a worm wheel rim of a double gear consisting of a worm wheel rim and a bevel wheel rim), and a second drive of the two drives has a second motor which drives a worm shaft that drives a worm wheel rim of a double gear consisting of a worm wheel rim and a bevel wheel rim. The swash plate is arranged between the two bevel wheel rims, which face each other and lie on a common axis.
