Described is a method and a device for screen calibration for the true-to-original reproduction of surface colors, the spectral reflection distribution of which is known, wherein by setting parameters the screen can be influenced using software and an electronic controller in each partial region of the screen. The disclosure is characterized in that an observer adapts the reproduced color impression of the screen to the color impression of an original in each partial region of the screen, wherein the original is compared to the screen colors immediately thereafter on the screen surface and the screen parameters are varied until the color impressions of the original and of the screen appear identical to the observer on the respectively viewed partial screen, viewed from a predefined observer angle, and the settings performed are stored in a screen profile.

A device for screening of outside light from the view of a video monitor is described. The device is constructed such that it may be fully or partially deployed, allowing for various configurations. In the fully collapsed configuration, the invention permits the user to employ the monitor without the light blocking shades as well. In a preferred embodiment, the device additionally includes a light source for illuminating the surface of the monitor.

Device for shading extraneous light and for creating defined lighting conditions on a monitor

An MR system for interventional procedures, includes an MR imaging device and an interventional instrument, for example a catheter. The MR device is arranged to acquire images of a part of an object. The entire catheter can be imaged in an MR image by providing a conductor loop which comprises two non-magnetic conductors which are situated at some distance from one another underneath the surface of the catheter, and extend along substantially the entire length of the catheter. Furthermore, the catheter may be provided with a conductor loop and a coil in a location on the catheter. By separate adjustment of the current flowing through the conductor loop and the coil, it is possible to image the location on the catheter with a contrast which deviates from that of the remainder of the catheter.
