  • Patent number: 7010149
    Abstract: A method of fusion of a first digital radiographic image obtained as a result of scanning with a second digital radiographic image obtained by magnetic resonance imaging (MRI). A CT interval of gray levels is selected first in the scanner image. Each pixel of the scanner image having a gray level lying within the CT interval is then replaced by a pixel obtained by digital processing of the pixel of the same coordinates as the MRI image. The final image corresponds to the scanner image in which the pixels of gray levels lying within the CT interval have undergone the digital processing.

  • Publication number: 20050249392
    Abstract: An automatic segmentation of the left or right cavities of the heart muscle is carried out. Once it is decided which cavities have to be isolated, three steps are implemented. A first step is performed to determine which is the volume comprising the cardiac cavities in a volume image resulting from an examination. This first step comprises a thresholding operation and an erosion, and then the determining of the greatest connected component. In a second step, an identification) is made of the left and right cavities. In a third step, a precise reconstruction is made of the contours of the left or right cavities for which it is sought to make the segmentation. The reconstruction is done by the watershed algorithm.

  • Publication number: 20050152587
    Abstract: Certain embodiments of the present invention provide a system and method for displaying a set of data with a virtually dissected anatomical structure. In an embodiment, the anatomical structure is a colon and various attributes of the colonic lumen are assigned a color. In an embodiment, a virtual dissection of the colon is created by mapping a three-dimensional data set to a two dimensional data set. A plurality of display index values are computed which correspond to the three-dimensional data set. Various colors are assigned to specific display index values. The three-dimensional display index values are mapped to a two-dimensional set of display index values. As directed by a user, various color cues may be displayed with the virtually dissected lumen to provide color highlights to various aspects of the colon, such as highlighting shape, fluid, or fecal presence.

  • Publication number: 20050094858
    Abstract: Certain embodiments of the present invention provide a system and method for automatically synchronizing multiple images. Multiple image sets of a single object are converted into a one dimensional data stream used to synchronize multiple image sets. A common reference point is located in the image sets. Various landmarks of the object are also located in the image sets. Corresponding landmarks among the image sets are noted. Distances from landmarks to the reference point and distances between landmarks are determined. Locations of the landmarks in relation to each other and in relation to the reference point are used to locate landmarks in another image set that correspond to landmarks in a selected image set. A first location in an image set may be identified using a first indicator. A second indicator corresponding to the location of the first indicator may then be determined in another image set.

  • Patent number: 6888916
    Abstract: 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.

  • Patent number: 6829379
    Abstract: One embodiment of the present invention is a method for analyzing tubular structures in a patient, including steps of: selecting a region of interest and a location within the region of interest from a displayed tube-shaped tree representative of a tubular structure in a patient; identifying a centerline of a structure within the tube-shaped tree within the region of interest; and displaying one or more views of the region of interest. The view or views are selected from at least a segmented 3-D view having the region of interest identified, a curved view of the selected branch, a reformatted view dependent upon the identified centerline, and a 3-D view dependent upon the identified centerline.

  • Publication number: 20030187358
    Abstract: A method of creating 3D models to be used for cardiac interventional procedure planning. Acquisition data is obtained from a medical imaging system and cardiac image data is created in response to the acquisition data. A 3D model is created in response to the cardiac image data and three anatomical landmarks are identified on the 3D model. The 3D model is sent to an interventional system where the 3D model is in a format that can be imported and registered with the interventional system.

  • Publication number: 20030169914
    Abstract: Method and system for processing vascular radiography images which have been reconstructed by three-dimensional modelling, in which: from this three-dimensional modelling there is determined a three-dimensional model known as the masked model which features the calcified elements and the prosthetic elements, but not the vascular elements; a three-dimensional model known as the subtracted model, which features the vascular elements alone, is determined; these two models are merged, weighting their voxels so as to increase the contrast between the images of the masked model and the images of the subtracted model; and summing the voxels thus weighted.

  • Patent number: 5412763
    Abstract: In order to display a portion of a physical structure on a screen, an intermediate "pointer" memory is created. The addresses of memory words in the pointer memory correspond to the coordinates of pixels on a display screen, or in equivalent manner to the corresponding addresses of memory words in an image memory. The information loaded into the memory words of the pointer memory is representative of addresses in an "original" memory whose collection of memory words represents the structure under investigation. It is shown that by using the pointer memory it is possible for each voxel of the structure to establish quickly the coordinates of the position at which it ought to appear on the screen, and thus the address of the corresponding memory words in the pointer memory, by using previously-calculated memory addresses for the pointer memory.
