A method for the merged display of first image information captured using a first imaging device with second image information captured using a second imaging device is provided. The first imaging device records fluorescence images of the area under examination. A second 3D image data record of the area under examination is recorded using an examination procedure based on electromagnetic radiation, such as computer tomography (CT) or magnetic resonance imaging (MRI). The 3D fluorescence image data record and the second 3D image data record are registered with one another, and one or more fluorescence-optically marked, relevant areas of the examination volume, on the basis of the mapping rules determined by the registration process, are displayed on a monitor.

In order, despite a plurality of terminals, to enable their freedom of movement on the one hand and an unimpeded treatment process on the other hand to be guaranteed, there is provision in accordance with the invention, for recording the devices in their envisaged spatial distribution, especially by at least one camera, to check this distribution as regards a sufficient freedom of movement of the devices, especially by a processing or control unit, and to feed back a corrected distribution, especially by at least one video projector.

Catheter for inserting into a hollow organ, in particular a blood vessel, wherein at least one tube- or balloon-like flexural element () which can be filled with a filling medium is provided inside the catheter, which flexural element is flexible in the non-pressurized state and stiffens as a result of pressure buildup internally and assumes a predetermined curved shape.

Catheter

Disclosed is a method for registering images of an object according to which a landmark that is common to the images is first identified, and the transformations in relation to the remaining degrees of freedom are determined by means of a position alignment that is not based on the landmark.

Method for determining a transformation of coordinates of different images of an object

A device for reproducing three-dimensional data has a plurality of image points() that include a plurality of laser light sources(), in front of which is arranged a lens(). Since the laser light sources() of an image point() radiate in different directions, different images can be projected in different radiation directions(). Since eyes () of an observer perceive different images depending on the viewing direction, a spatial visual impression is produced.

The invention relates to a method for recording two-dimensional images on the interior of a perfused blood vessel by means of optical coherence tomography using a catheter with an integrated imaging device, via which light is radiated and light reflected from the vascular wall is recorded, whereby a fluid containing a medium having a higher refractive index than blood plasma and/or cytoplasm is injected, via the catheter, into the vascular area to be recorded, to enable imaging to be carried out, whereby said fluid is a mixture of autologous blood and the medium.

A controller of an image-generating medical engineering assembly receives a selection of an image valuation method from a user. It subsequently automatically adjusts selection-specific, positioning-independent operating parameters of the recording arrangement and or provides the user with instructions for adjusting the positioning-independent operating parameters. In response to a user's start input the controller captures by means of a recording arrangement of the image-generating medical engineering assembly a sequence of successive two-dimensional images of an iteratively moving object being examined and capturing instants thereof as well as a phase signal of the object being examined and archives the sequence of images, capturing instants and the phase signal.

In order to improve the quality of cross-sectional images, which have been recorded along a longitudinal axis of a vessel of a body, it is proposed to add successive cross-sectional images to an overall cross-sectional image. Artifacts in the cross-sectional images are hereby weakened and pathological structures to be detected are high-lighted.

In a method and an apparatus for detecting the roughness of a vessel in a living subject, an in vivo image of an inner contour of the vessel wall is obtained using an imaging modality. A dimensional value characteristic of the complexity of the inner contour is calculated from the image information in the image describing the inner contour.

Registering intra-operative image data sets with pre-operative 3D image data sets on the basis of optical surface extraction

The present invention relates to a method for imaging using an image-generating, endoluminal instrument () by means of which a sequence of 2D image data of a hollow channel (), in particular a vessel, of an object under investigation is recorded, wherein the images are recorded in a known temporal relation to a periodic movement of the object under investigation and spatial coordinates of the image are captured by means of a position sensor during each recording of an image () and stored as position data () together with the 2D image data of the image (). The method is characterized in that first position data () which does not lie in a predefinable movement phase of the object under investigation is corrected, before or after being stored, by interpolation between second position data () which does lie in the specified movement phase and/or by subtraction or addition of predetermined values. By means of the method a movement correction of the data can be performed without the need to reduce the volume of recorded image material.

Method for endoluminal imaging with movement correction

The device according to the invention ensures accurate and in particular sensitive navigation of the probe, which can be inserted into a body, despite the fact that the remote control uses simple means, by means of a movement (MR;MB;MP) corresponding intuitively to the navigation of a probe using the control device (). Intuitive operation can be converted in particular using an inventive U-shaped embodiment of the control device (). Sensitive controllability can be increased by transmitting the mechanical interaction between the probe and an environment under examination to the control device () and thus directly to the operating hand () by means of inventive feedback.
