    摘要: The invention relates to a viewing system and a method for detecting an object of interest in a sequence of images (IS). Said object of interest is detected by first locating localizers related to said object of interest and by locating borders (BL) related to said object of interest using the location (LI, LZ) of said localizers. The viewing system according to the invention is able to produce a sequence of enhanced images in which the object of interest is enhanced, to measure some characteristics and to build a three dimensional representation of said object of interest. The viewing system is also able to register and combine said sequence of enhanced images with a sequence of reference images.

    摘要: A method for use in a medical viewing system for processing for display a sequence of images of a medical intervention comprising manipulating a tool such as a stent (25) within an artery. Two markers (21, 22) are provided on the tool support (10) and the method includes extracting these markers (21, 22) to yield marker location information, from which tool location information can be derived. The image of the tool within the sequence of images is then enhanced relative to the background. The background can be additionally blurred by simulating or effecting relative movement of the image detector and the stent (25) by, for example, zooming in on the stent (25) or rotating the detector relative thereto, during acquisition of the sequence of images.

    摘要: A medical examination apparatus including an imaging means (2,3), a viewing system (4), wherein image data processing means (5) is arranged to facilitate production of different images of a feature of interest such that the pose of the feature is comparable in the different images. The image data processing means (5) estimates the pose of the anatomical feature in a first image generated by the imaging means, produces imaging means control data indicative of the desired imaging geometry for controlling one or more parameters of the imaging means (2,3) for producing a further image having the feature of interest in the estimated pose, and outputs the produced imaging means control data. The output control data may be output in a viewable form and/or output directly to the imaging means (2,3) so as automatically to control the parameters thereof. The output control data can also control the imaging means so as to produce an image having desired intensity characteristics.
