摘要： The invention relates to an image display apparatus for displaying an image like a three-dimensional medical image of an object. A template providing unit (3) provides a template defining display parameters for displaying the image based on anatomical features of the object, and an anatomical feature detecting unit (4) detects an anatomical feature in the image. A display parameter determining unit (5) determines a display parameter defining, for example, a desired view, based on the detected anatomical feature and the template, and a display unit (8) displays the image by displaying, for example, the desired view, in accordance with the determined display parameter. This allows the image display apparatus to show the image on the display in a desired usual way as defined by the template, even if in the originally provided image the object is shown in an unusual way.

摘要： When adapting models of anatomical structures in a patient for diagnosis or therapeutic planning, an atlas (26) of predesigned anatomical structure models or image volumes can be accessed, and a segmentation of one or more such structures can be selected and overlaid on an a 3D image of corresponding structure(s) in a clinical image (52) of a patient. A user can click on an initially unapproved segmentation 5 landmark (72) on the patient image (52), reposition the unapproved landmark, and approve the repositioned landmark. Remaining unapproved landmarks (72) are then repositioned as a function of the position of the approved landmark (92) using one or more interpolation techniques to adapt the model to the patient image on the fly.

摘要： When modeling anatomical structures in a patient for diagnosis or therapeutic planning, an atlas (26) of segmented co-registered CT and MRI anatomical structure reference images can be accessed, and an image of one or more such structures can be selected and overlaid with an MRI image of corresponding structure(s) in a clinical image of a patient. A user can click and drag landmarks or segment edges on the reference MRI image to deform the reference MRI image to align with the patient MRI image. Registration of a landmark in the patient MRI image to the reference MRI image also registers the patient MRI image landmark with a corresponding landmark in the co- registered reference CT image, and electron density information from the reference CT image landmark is automatically attributed to the corresponding registered patient MRI landmark.

摘要： When modeling anatomical structures in a patient for diagnosis or therapeutic planning, a plurality of surface mesh models (48) are overlaid on 3D patient image data, and manipulated to conform to the patient image. To mitigate mesh model overlap, each potential field (12) of each polygon (10) in each mesh model (48) is demarcated with a plurality of points, and each point is mapped to a bin in a hash table using a spatial hash function (50). Bins having points from polygons (10) in different mesh models (48) are identified, and only those polygons (10) corresponding to the points in the identified bins are subjected to a collision detection procedure (54). If a given point of a first potential field surrounding a first polygon in a first mesh model is determined to intrude or penetrate a second potential field surrounding a second polygon in a second mesh model, then a repulsive force is applied to the point or the entire first polygon to repel the first polygon from the second polygon and prevent mesh model overlap. The hash function (50) facilitates reducing the number of polygons for which collision detection (54) is applied, thereby speeding the concurrent segmentation of multiple mesh models.

摘要： The invention relates to a system (100) for registering first image data and second image data,based on a first set of landmarks comprised in the first image data, the systemcomprising a second landmark unit (110) for mapping each landmark from the first set oflandmarks into the second image data space, based on local registration of a first data subset of the first image data, comprising the landmark, and the second image data, thereby creating a second set of landmarks comprised in the second image data, and a registration unit (120) for registering the firstand second image data,based on the first and second set of landmarks. The landmarks in the first image data may be defined by a user, for example. The second landmark unit (110) is arranged to locally register the first data subset with a second data subset ofthe second image data. During local registration, the second landmark unit is arranged to search for a local registration map for mapping the first data subset into the second image data to find the second data subset to be satisfactorily similar tothe first data subset. When enough landmarks of the first set of landmarks are mapped into the second image,the registration unit (120) is arranged to perform landmark-based registration of the first and second image data.
