Abstract: Techniques for generating a hollow model from a medical image are disclosed herein. In an example, a hollow model may be created within a medical imaging visualization application through the generation of a mask of an interior space of a segmented anatomical structure, the extrusion of a shell mask from the mask of the interior space, and the generation of a visualization of the shell mask within the medical imaging visualization application. For example, the mask may be provided as a layer in the medical imaging visualization application, allowing a user to visualize the produced shell mask of the hollow model from the perspective of the medical imaging. In further examples, the hollow model generation techniques may be used with techniques for shell region modifications, variable shell thickness, multiple shell layer, and trimming of shell endpoints.

Abstract: A computing system and method for generating, displaying and manipulating synthetic 2D and 3D brain tissue viability images and associated metrics from multiple perfusion maps derived from CT or other imaging system input image datasets. Stored linguistic tissue classification rules characterizing infarct, ischemic and/or normal or other tissue classes as a function of one or more perfusion parameters are used. The perfusion maps are normalized to normal brain tissue regions. Elements of the input image dataset are classified into one of the tissue classes as a function of the normalized perfusion maps and the classification rules. The classification includes ranking each of the plurality of tissue classes for elements of the input image dataset, and assigning one of the classes to elements of the dataset as a function of the ranks.

Abstract: A user interface for display or editing of a three dimensional medical image is provided on a display and is responsive to user inputs in a medical imaging system. The user interface includes a framing tool for defining a region of interest on the medical image. An image matrix is then provided on the user interface, which includes a plurality of cross-sectional images each corresponding to a cross-section of the medical image at one of a plurality of cut planes within the region of interest. One or more reference views of the medical image are also displayed, which each include a plurality of reference indicia, each of which corresponds to a location of one of the plurality of cut planes.

Abstract: Methods and systems for medical imaging using an ergonomic patient head an arm support are provided. A support for medical imaging is provided that includes a lower body configured to engage a portion of a medical imaging system and an upper surface having a plurality of depressions configured to receive therein at least one of a head and arm of a patient.

Abstract: A peripheral device for manipulating 3D images comprising a gripping element to be manipulated by user, a transmission of command information to a processor as a function of shift and/or efforts applied by the user on the 3D device. An actuator is controlled by the user to control the processor to switch from one operating mode where the gripping element is used for manipulating 3D images to another operating mode where the device is used as a pointer or selection device and vice versa. The peripheral device is placed in a surgical theater and/or examination room, on the side of a table for patients.

Abstract: Equipment for an apparatus for mammography having a C-shaped arm having a radiation source at one of its ends and, at its other end, a breast support plate and image acquisition. The equipment is at the level of a portion on the side of the breast support plate or in the prolongation of such a portion, close to the main body of the C-shaped arm. The equipment has a shape with at least one projection and/or hollow set in the external surface of the apparatus and defines a zone able to be used as a secondary handle and/or armrest.

Abstract: A method and assembly for processing, viewing and installing command information transmitted via a peripheral device for manipulating 3D modelling image(s). The peripheral device is a gripping element manipulated by a user and has sensors which detect forces and/or displacements on the gripping element and, as a result of detected forces and/or displacements, generate command information, some corresponding to translation or zoom components, and others to rotation components for the movement to be conferred to a spatial representation of the 3D modelling. In a first operating mode a set of command information is processed to modify the displayed image(s) by imparting thereto only movements of rotation in space and in that in a second operating mode a set of command information is processed to modify the displayed image(s) by imparting thereto only movements of translation or a zoom effect. The method is applicable to a surgical theater and/or examination room.
