摘要： 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.

摘要： 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.

摘要： A system and method for estimating vascular flow using CT imaging include a computer readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, cause the computer to acquire a first set of data comprising anatomical information of an imaging subject, the anatomical information comprises information of at least one vessel. The instructions further cause the computer to process the anatomical information to generate an image volume comprising the at least one vessel, generate hemodynamic information based on the image volume, and acquire a second set of data of the imaging subject. The computer is also caused to generate an image comprising the hemodynamic information in combination with a visualization based on the second set of data.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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. It is shown that by using such previously-calculated memory addresses, the need to perform multiplications is avoided, as is the need to perform repeated accesses to the original memory. Very high speed processing is obtained in this way.

摘要： A method includes generating a first response including a plurality of potential first objects of interest of a first shape from data regarding a region of interest (ROI), generating a second response including a plurality of second objects of interest for a second shape different than the first shape from the data regarding the ROI, and performing a morphological closing on the second response to produce a second cleaned response including a plurality of completed second objects. The method also includes decreasing the number of potential objects of interest in the first response by deleting any potential first objects that overlap any completed second objects to obtain a cleaned first response, and generating an image using at least one of the first cleaned response and the second cleaned response.
