摘要:
A method, computer program and device for creating a viewing protocol for medical images is described. At least a first site of interest is identified in a medical imaging data set captured from the patient. Patient record data or computer assisted detection information can be used to identify the site of interest, which may be a potential lesion. A viewing protocol for displaying medical images to a user is planned. The viewing protocol includes a viewing path along which an image of the site of interest will be displayed. The viewing protocol also includes a trigger associated with the site of interest. When the trigger event is encountered the dynamic mode of image display is reconfigured to dynamically highlight the site of interest. The viewing protocol can then be used to control the display of images so as to provide, for example, a virtual endoscope.

The invention relates to a system (100) for retrieving a volumetric image data subset comprised in a data storage (105) of volumetric image data sets, the system comprising: a first query unit (111; 113) for composing a first query for searching the data storage (105) for a volumetric image data set comprising the volumetric image data subset; a second query unit (112; 113) for composing a second query for searching the volumetric image data set for the volumetric image data subset, the second query comprising anatomical structure information for identifying an anatomical structure within the volumetric image data set; a first determination unit (121; 123) for determining the volumetric image data set, based on the first query; a second determination unit (122; 123) for determining the volumetric image data subset of the volumetric image data set, based on the anatomical structure identified within the volumetric image data set, using the anatomical structure information comprised in the second query; and a retrieval unit (125) for retrieving the determined volumetric image data subset. The system is thus capable of retrieving a reduced amount of data describing the anatomical structure, i.e. a subset of a volumetric image data set.

The invention relates to the adaptation method (200) of adapting a geometric model to an image data comprising a region selection step (230) for selecting a region of the geometric model and a manual adaptation step (235) for manually adapting the geometric model to the image data using a set of characteristics of the region comprised in the geometric model. Using a region-specific characteristic from the set of characteristics of the selected region, such as a region-specific parameter determining the deformation range, for manually adapting the geometric model to the image data, requires relatively fewer user interactions.

The invention relates to a method (100) of adapting a geometric model to an image data comprising determining a first partial transformation for mapping a first part of the geometric model into the image data and a second partial transformation for mapping a second part of the geometric model into the image data. By determining the first partial transformation of the first part of the geometric model and the second partial transformation of the second part of the geometric model, the geometric model can assume more shapes and therefore can be more accurately adapted to an object comprised in the image data.

The invention relates to a method for the registration of a series of at least three temporally successively acquired images (I1–In) of an object. Individual images (I2–In) to be registered are transformed into registered images (I2′-In′) using an individual mapping rule (T2–Tn). A similarity measure (M) is used to determine a mapping rule (T2–Tn), where to achieve a higher registration accuracy, a common similarity measure (M) of all images (I1′-In′) in order to determine the mapping rules (T2–Tn) for all images is implemented. The invention also relates to a corresponding registration device.

摘要:
A method includes identifying a plurality of different anatomical sub-regions of the cardiovascular system of a subject in image data of the subject based on a subject specific cardiovascular anatomical model, wherein the plurality of different regions corresponds to regions where calcifications occur, searching for and identifying calcifications in the sub-regions based on voxel grey value intensity values of the image data, and generating a signal indicative of one or more regions of voxels of the image data respectively corresponding to sub-regions including identified calcifications. A computing system (118) includes a processor that automatically determines a plurality of different groups of voxels of image data of a subject, wherein each group of voxels corresponds to a different sub-region of the cardiovascular system of the subject and each group of voxels corresponds to a region that includes a calcification identified in the image data.

The invention relates to a method of measuring geometric variables of a three-dimensional structure contained in an object from at least on image representing the object, having the following steps:—use of a deformable first model describing the structure, the shape of which model can be described by parameters,—adjustment of the first model to the structure in the image,—determination of the parameters at which the first model exhibits optimum conformity with the structure,—use of a deformable second model describing the structure, which second model in shape corresponds to the first model, and which in addition contains at least one geometric variable,—modification of the second model according to the parameters determined, and—derivation of the geometric variable(s) from the modified second model.
摘要:
The invention relates to evaluating medical image information, in particular physical properties of an object (32). When preparing a surgical procedure e.g. a minimally invasive procedure, it may be beneficial to plan the procedure in detail before starting the operation. Thus, obtaining precise information about physical properties of an object (32), e.g. a diameter value (34, 36) of an anatomical structure may be beneficial. Accordingly, a method and a system for determining a physical property (34, 36) of an object (32) is provided, which employs local object context information (38) for determining a local physical property of the object (32).
