摘要： A system comprises a catheter including a lens, for acquiring optical coherence tomography images within the vessel of interest as the catheter is being retracted from the vessel in the presence of contrast agent. An X-ray imaging system interface receives a first set of X-ray images of an anatomical region including the vessel of interest containing the catheter. The first set of X-ray images are acquired at points corresponding to the particular points within a heart cycle, while the catheter is stationary in the vessel, in response to a heart electrical activity representative signal and in the absence of contrast agent. An image data processor associates the received X-ray images and corresponding optical coherence tomography image data derived at corresponding time points within respective acquisition heart cycles.

摘要： A system automatically processes different medical image sequences facilitating comparison of the sequences in adjacent respective display areas. An image data processor, identifies first and second mask images of first and second image sequences respectively as images preceding introduction of contrast agent and determines a translational shift between the first and second mask images. The image data processor transforms data representing individual images of at least one of the first image sequence and the second image sequence in response to the determined translational shift to reduce mis-alignment of the individual images of the first image sequence relative to the individual images of the second image sequence. A display presents first and second image sequences corrected for mis-alignment, in substantially adjacent display areas to facilitate user comparison.

摘要： A method generates a two dimensional (2D) medical image through a three dimensional (3D) imaged volume of patient anatomy at a desired position, by storing 3D image data representing a 3D imaging volume including vessels in the presence of a contrast agent. The 3D image data comprises, data identifying multiple voxels representing multiple individual volume image element luminance values and luminance distribution data for individual voxels of a vessel in the 3D image data. For multiple individual voxels of a 2D image, the method determines composite luminance distribution data of an individual voxel in the 2D image by combining luminance distribution data of the 3D image data of multiple identified voxels substantially lying on a projection line from a source point to the individual voxel and generating data representing the 2D image using the determined composite luminance distribution data of the multiple individual voxels.

摘要： A system creates a visually (e.g., color) coded 3D image that depicts 3D vascular function information including transit time of blood flow through the anatomy. A system combines 3D medical image data with vessel blood flow information. The system uses at least one repository for storing, 3D image data representing a 3D imaging volume including vessels, in the presence of a contrast agent and 2D image data representing a 2D X-ray image through the imaging volume in the presence of a contrast agent. An image data processor uses the 3D image data and the 2D image data in deriving blood flow related information for the vessels. A display processor provides data representing a composite single displayed image including a vessel structure provided by the 3D image data and the derived blood flow related information.

摘要： An IVUS catheter is advantageously provided with a particular radio-opaque pattern enabling detection of catheter rotation angle with respect to an X-ray imaging source for co-registering IVUS image data with angiographic X-ray or CT image data, for example. An ultrasound catheter system supports orientation and display of intra-vascular ultrasound imaging data. The system comprises an ultrasound catheter for acquiring ultrasound images comprising a body having a pattern of radio-opaque material on the external surface of the catheter body. The pattern varies with angular rotation of the catheter and indicates an angle of rotation of a predetermined reference orientation of the catheter relative to an X-ray radiation source, so that an X-ray image of the catheter body indicates the pattern and the pattern is analyzable by an image data processor to determine the angle of rotation.
