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 system and method for segmenting and editing anatomical objects from medical images is disclosed. The system may be a medical diagnostic imaging system. A computer unit may execute computer software for segmenting anatomical objects from medical images. The computer software may extract an anatomical object from planar curves. The computer software may extract an anatomical object by computing the centerline of the anatomical object. A set of reformatted images may then be derived based on the centerline of the object. A user may then provide input in the form of user drawn contours on a plurality of reformatted images. In an embodiment the reformatted images may include a reformatted longitudinal view, a curved reformatted view, or a lumen view. The user drawn contours may correspond to the boundaries of the anatomical object to be segmented. The anatomical object may then be extracted based on the user drawn contours.

摘要： A method for selecting and/or labeling a vessel image includes operating an imaging system to obtain reconstructed image data including a volume having vessels therein. A bone removal routine is then applied to the reconstructed image data to produce a bone-free image. An initial point on a main vessel in the bone-free image is located, and bifurcation points and branches departing from the main vessel are identified. An adjacency graph of each branch coming from the main vessel is built. The method includes either or both of selecting and displaying a best or at least a favorable path through the vessels in accordance with predetermined criteria using the adjacency branch, or labeling and displaying branches of the main vessel.

摘要： 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.
