摘要： A medical viewing system including an imaging means (2,3) and 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 of interest is comparable in the different images. The image data processing means (5) estimates the pose of the feature of interest in a second image relative to the pose thereof in a first image, typically generated at a different time, and applies an affine transformation, for example to the second image, so as to produce a transformed second image in which the feature of interest has substantially the same pose as in the first image. The image data may also be processed so as to normalize the intensity characteristics of the images to be compared. Gross differences in pose can be eliminated by processing the image data so as to generate control data indicating how to set up the imaging apparatus to produce an image having the feature of interest oriented substantially in a desired pose.

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： The invention relates to a system and a method for detecting an object of interest in a sequence of medical images. Said viewing system comprises alarm detection means (20) for detecting a set of alarms of said object of interest in a medical image (I’) at time t, in which an alarms is a set of data describing a possible location of the object. It further comprise temporal tracking means (30) for iteratively creating a set of tracks (T’) at time t by associating alarms of said set of alarms (A’) with tracks (T’1) at time t-1 and for choosing a track from among said set of tracks at time t in accordance with a merit criterion. Said track at time t is ended by an alarm which corresponds to a detection of said object of interest in said medical image at time t. Said viewing system advantageously accumulates temporal proofs for confirming or infirming spatial detections of alarms at time t. Detection of the object of interest is therefore made more robust to errors.

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.
