摘要： To intraoperatively generate an updated volume data set in which a image information of biological tissue is volume data set representing reconstructed from a series of n 2D biological tissue x-ray projections, one version, in intraoperatively acquired m 2D biological tissue x-ray projections the biological tissue 2D contour is segmented and this is back-projected in the reconstructed volume data set. In another version, in the volume data set the biological tissue 3D contour is segmented and this is projected in intraoperatively acquired m biological tissue 2D x-ray projections. The 3D contour is visually repositioned by projection in the m 2D x-ray projections in the volume data set, until its projection is substantially congruent with the biological tissue image information in the respective 2D x-ray projections. In both versions, a volume data set updated around the intraoperatively determined biological tissue 3D contour is generated.

摘要： A method and CT scanner are proposed for the production of tomographic section images, in particular X-ray CT images, of a periodically moving object with periodically changing movement and rest phases. For scanning, a number of focus detector combinations with flat detectors are moved on coaxial spiral paths and movement signals from the moving object are measured at the same time in order to detect movement and rest phases. Further, the time correlation between the movement data and the detector output data stored and axial segment image stacks are then reconstructed independently of one another from sub-segments of the spiral paths using the detector output data from each detector which represent a rest phase of the moving object. Additionally, segment image stacks from the n spiral paths of the n focus detector combinations at the correct time are added up in a complementary angle form and in layers to form 180° tomography section images. The axial segment image stacks are reconstructed in a first step from double-inclined reconstruction planes. Further, in a second step, they are reformatted to produce axial segment image stacks, and detector data from a number of successive movement periods are used for this purpose.

摘要： Preprocessing methods of this invention remove data relating to cavities of the heart, and improve density mix of parts left therein during CT imaging, so as to allow coronary arteries to be more accurately tracked with conventional tracking algorithms than currently possible. An embodiment comprises: obtaining an original CT voxel dataset comprising a plurality of voxels; creating a heart voxel dataset from the original voxel dataset comprising only voxels belonging to the heart; creating a heart minus cavities voxel dataset by removing voxels belonging to the left and right ventricles, the left and right atriums, and the aorta from the heart voxel dataset; enhancing predetermined voxels in the heart minus cavities voxel dataset to create an enhanced heart minus cavities voxel dataset; and mixing an intensity of the original CT voxel dataset with an intensity of the enhanced heart minus cavities voxel dataset to create the pre-processed voxel dataset.

摘要： One or more techniques are provided for deriving motion data from a set of CT projection data. The techniques calculate moments associated with consistency conditions for the projection data to derive motion data from the projection data. One aspect of the present techniques uses the calculated moments to select projection data sets based upon the presence or absence of motion between the projection data sets. Periodicity information may then be extracted from the selected projection data sets. Another aspect of the present techniques uses projection data acquired by a slowly rotating volumetric CT gantry to allow the separation of a corruptive signal from a desired motion signal. Once separated, the desired motion signal may be used to identify projection data at a desired phase of motion.
