摘要:
Systems and methods for retrieving, manipulating, and viewing 3D image objects from 3D virtual microscope slide images are provided. An image library module provides access to the imagery data in a 3D virtual slide and constructs 3D image objects that are coextensive with the 3D virtual slide or a 3D sub-portion thereof. From within the 3D image object, cross layer planar views spanning various depths of the 3D virtual slide are constructed as well as 3D prisms and other shaped image areas. The image library module allows a 3D image object to be sliced into horizontal and vertical views, skewed cross layer views and regular and irregular shaped 3D image areas for viewing by a user.

A method and system for scene parsing and model fusion in laparoscopic and endoscopic 2D/2.5D image data is disclosed. A current frame of an intra-operative image stream including a 2D image channel and a 2.5D depth channel is received. A 3D pre-operative model of a target organ segmented in pre-operative 3D medical image data is fused to the current frame of the intra-operative image stream. Semantic label information is propagated from the pre-operative 3D medical image data to each of a plurality of pixels in the current frame of the intra-operative image stream based on the fused pre-operative 3D model of the target organ, resulting in a rendered label map for the current frame of the intra-operative image stream. A semantic classifier is trained based on the rendered label map for the current frame of the intra-operative image stream.

A method computerized optically analyzes methods of conventional, preferably non-contrast-enhanced, MR (magnetic resonance) images of the liver. The method enables the detection of steatohepatitis by NASH-MRI and significant fibrosis by Fibro-MRI in patients suffering from NAFLD. The method enables forecasting the rate of disease progression, to support therapeutic decision-making, and to monitor potential therapeutic effects.
摘要:
The present invention relates to a method for classification of an organ in a tomographic image. The method comprises the steps of receiving (102) a 3-dimensional anatomical tomographic target image comprising a water image data set and a fat image data set, each with a plurality of volume elements, providing (104) a prototype image comprising a 3-dimensional image data set with a plurality of volume elements, wherein a sub-set of the volume elements are given an organ label, transforming (106) the prototype image by applying a deformation field onto the volume elements of the prototype image such that each labeled volume element for a current organ is determined to be equivalent to a location for a volume element in a corresponding organ in the target image, and transferring (108) the labels of the labeled volume elements of the prototype image to corresponding volume elements of the target image.
摘要:
[Aim] To shorten required processing time and reduce a memory amount for operations when an area is extracted from an image by using a graph cut method. [Solution Means] An image obtainment unit (10) obtains plural CT images from an X-ray CT apparatus (2), and generates a three-dimensional image (M0). A low-resolution image generation unit (12) performs multi-resolution transformation on the three-dimensional image (M0), and generates a low resolution image (ML). A first extraction unit (14) extracts a specific area, such as the liver region, from the low resolution image (ML) by using a graph cut method. An outline area setting unit (16) sets the outline of the liver region extracted from the low resolution image (ML) in the three-dimensional image (M0), and sets an outline area including the outline in the three-dimensional image (M0). A second extraction unit (18) extracts the outline of the liver region from the outline area, and also extracts the liver region from the three-dimensional image (M0).
摘要:
The present invention relates to a method for assessing the presence and/or the severity of a lesion in an organ or tissue of a subject through automated analysis of at least one image of said organ or tissue, wherein said organ or tissue is preferably a liver organ or liver tissue, comprising the calculation of a score combining descriptors of said image, wherein said method comprises the steps of: a. measuring on said at least one image at least two descriptors of said at least one image; b. mathematically combining said at least two descriptors in a score; and c. assessing the presence and/or the severity of a lesion in the organ or tissue based on the value of the score calculated at step (b).
摘要:
When performing image diagnosis using a three-dimensional medical image representing a subject's internal structure constituted by branch and peripheral structures, allowing a necessary and sufficient treatment target area to be identified for an abnormal area. A lesion area detection unit (33) detects an abnormal peripheral structure (lesion area), pulmonary blood vessel extraction unit (32) extracts a branch structure (pulmonary blood vessel) from the three-dimensional medical image, associated blood vessel identification unit (35) identifies an associated branch structure functionally associated with the abnormal peripheral structure based on position information of each point in the extracted branch structure, and associated lung parenchymal area identification unit (36) identifies an associated peripheral area (lung parenchyma) functionally associated with the identified associated branch structure based on the position information of each point in the extracted branch structure.
摘要:
System and graphical user interfaces are disclosed for liver disease diagnosis. A visual data manipulation page is used for manipulating one or more liver visual data sets, retrieved together with non-visual information associated with a subject and specific to a liver disease. The visual data manipulation page includes a first area for manipulating the one or more data sets and a second area for providing a plurality of selectable means to activate one or more data manipulation operations to be performed with respect to the one or more data sets displayed in the first area. When the first area is configured to manipulate more than one data set, each image is from a corresponding data set and images from different data sets can be displayed synchronously.
摘要:
A system and method for automatic detection of an object feature, such as a lesion, across a plurality of sets of image data, taken from the same subject, which may optionally be a human patient but which may also optionally be any type of animal or a non-biological subject.
