    摘要: The invention relates to a light-emitting apparatus (100) comprising an optical waveguide, particularly an optical fiber (1), for guiding a primary light beam (Bprim) into a light-splitting unit (101) which splits it into two or more partial light beams (B1, B3, B4) which are emitted in different directions and have different optical qualities, e.g. different spectral compositions or polarizations. The apparatus may optionally comprise a detector (4) for determining a Doppler shift (Δλi) in reflected light reentering the light-splitting unit (101). This renders it possible to measure simultaneously two or more spatially independent vector components of the flow velocity of a fluid, particularly of blood, surrounding the light-splitting unit (101).

    摘要: A catheter having ultrasound capability and a distal end extending along a longitudinal axis, the end being situated adjacent to a tissue of interest inside of a patient; at least one ultrasound transducer located in the end to direct ultrasound waves along the axis in a generally forward direction relative to the end; a variable-focus lens system located in the end, downstream of the transducer in the generally forward direction, the lens system being capable of variably focusing the ultrasound waves emitted by the transducer at various positions downstream of the lens and catheter end; optionally, a mirror located in the end, downstream of the transducer and the lens system in the generally forward direction, whereby the emitted ultrasound waves from the lens system are either reflected from the mirror and focused at a position substantially perpendicular to the longitudinal axis; or the emitted ultrasound waves from the lens system substantially bypass the mirror in unreflected form and are focused at a position downstream of the transducer, the lens system and the mirror in the generally forward direction along the longitudinal axis; and imaging means for translating the focused ultrasound waves from the lens system reflected and/or unreflected by the mirror into three-dimensional images and communicating the images in viewable form to a human operator that is external to the patient. A method of measuring, imaging and viewing blood flow velocity and patterns in a blood vessel and aneurysm, as well as monitoring vaso-occlusive coil placement in an aneurysm during a surgical intervention using the catheter, is also disclosed.

    摘要: A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in.

The system further includes a spatial reference for spatially correlating the X ray image and the camera image, where the spatial reference is detectable in the X ray image and in the camera image. A data processor configured for rendering the camera image and the X ray image into a composite image on the basis of the spatial reference.

    摘要: The present invention relates to the determination of brain deformation. The invention relates in particular to a device for tracking brain deformation, an imaging system for tracking brain deformation, a method for tracking brain deformation, a method of operating a device for tracking brain deformation, as well as to a computer program element and a computer readable medium. For providing enhanced information about the brain deformation, a first 3D representation (112) of a cerebrovascular vessel structure of a region of interest of an object is provided (110) and (114) a second 3D representation (116) of the cerebrovascular vessel structure. Then, at least a part of the first 3D representation is elastically three dimensionally registered (118) with at least a part of the second 3D representation. A deformation field (122) of the cerebrovascular vessel structure is determined (120) based on the elastic registration. The determined vessel deformation is applied (124) to a brain structure representation to determine a deformation (126) of the cerebral structure. For example, planning data (130) for an intervention of the cerebral structure is provided (132) and the determined deformation of the cerebral structure is applied (134) to the planning data to generate deformation adjusted planning data (136).
