Abstract: An image processing system, comprising an input interface (IN) for receiving a plurality of input images acquired of test objects. The system further comprises a material type analyzer (MTA) configured to produce material type readings at corresponding locations across said input images (IM(CH)). A statistical module (SM) of the system is configured to determine based on said readings an estimate for a probability distribution of material type for said corresponding locations.

Abstract: The present invention relates to a method of calculating a surgical intervention plan. Based on surface data of the patient, a surface representation of a part of the patient's body is created. From a database, a plurality of surgical methods may be selected and the geometrical parameters of a surgical plan can be adapted based on each individual surgical method. Therefore, the surgeon may easily select, which of the surgical method is appropriate for the planned surgical intervention. Furthermore, the surgical intervention plan which has been adapted according to the finally selected surgical method may then be projected onto the skin of the patient such that a drawing of the incision lines is facilitated. Furthermore, the use of a remotely activatable pen based on the current position of the pen and based on the finally selected surgical plan is presented.

Abstract: The present invention provides for means for linking breast lesion locations across imaging studies. In particular, a generic three-dimensional representation of the female breast is used. Automatic translation of the lesion location into standard clinical terminology and aligning the breast model with individual patient images is comprised. Moreover, a mechanism for linking image locations showing a lesion to a location in the breast model is presented. If desired, a region of interest can be calculated by a region of interest definition module that predicts a region of interest of a known lesion in terms of the breast model representation in a new imaging study.

Abstract: A system for displaying a plurality of registered images is disclosed. A first viewport unit displays a representation of a first image dataset in a first viewport. A second viewport unit displays a representation of a second image dataset in a second viewport. A position indication unit enables a user to indicate a position in the first dataset displayed in the first viewport, to obtain a user-indicated position. A corresponding position determining unit determines a position in the second image dataset corresponding to the user-indicated position, to obtain a corresponding position in the second image dataset, based on correspondence information mapping positions in the first image dataset to corresponding positions in the second image dataset. The second viewport unit displays an indication of the corresponding position in the second viewport.

Abstract: A system for displaying a plurality of registered images is disclosed. A first viewport unit (1) displays a representation of a first image dataset (4) in a first viewport (201). A second viewport unit (2) displays a representation of a second image dataset (5) in a second viewport (202). A position indication unit (7) enables a user to indicate a position in the first dataset (4) displayed in the first viewport (201), to obtain a user-indicated position. A corresponding position determining unit (8) determines a position in the second image dataset (5) corresponding to the user-indicated position, to obtain a corresponding position in the second image dataset (5), based on correspondence information (9) mapping positions in the first image dataset (4) to corresponding positions in the second image dataset (5). The second viewport unit (2) displays an indication of the corresponding position in the second viewport (202).

Abstract: The invention relates to an image generation apparatus (1) for generating an image of a deformable object (5) like a woman's breast. A first image generating unit (2) like an ultrasound head generates a first image of the object covered by a flexible cover element (6), wherein a shape sensing and localization unit (10), in particular, a fiber-optic shape sensing and localization unit, determines the shape and position of the cover element. The apparatus further comprises a position determination unit (11) for determining the position of the first image generating unit relative to the cover element. Information about the deformation of the deformable object with respect to the first image can therefore be provided, which can facilitate reviewing the first image, especially reviewing of breast images. For instance, this information can facilitate a comparison of breast images acquired by different imaging modalities.
