    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.

    摘要: 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.

    摘要: 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: 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).
