    摘要： A system and method for managing medical image data items. A large image manager is used to store medical image data items external to a core PACS. Representative objects are generated and provided to the PACS to be incorporated into the core PACS workflows. The representative objects can be generated by extracted pixel data and metadata from the medical image data items. The representative objects are generated in a format compatible with the protocol used by the PACS workflows. Requests sent to the PACS for medical images can be re-routed to the large image manager to provide the requested images.

    摘要： A method and system to correct for alignment errors between assumed and actual geometric parameters of an acquisition geometry during image reconstruction in a chest tomosynthesis application includes receiving at least 2 raw projection images acquired on at least 2 different positions in a known acquisition geometry, determining an actual geometric parameter value by determining the minimum of a redundant planes cost function which is calculated for a varying range of the geometric parameter values, and which is determined by: a) at least one plane which intersects an X-ray source trajectory with at least two points, b) an intersection between the planes and a detector surface for which points the source positions are determined, and c) for which the parameters determining the intersection (λ, μ, l) are used for the construction of the cost function, applying the calculated actual geometric parameter value of the acquisition geometry for the image reconstruction of the plurality of images, characterized in that, a weighting function is applied to the plurality of acquired images prior to calculating the cost function.

    摘要： A system and method for printing medical images is provided. The system includes a client device and a server in data communication with the client device. The client device includes a communication subsystem for receiving medical images from the server; a user interface device for displaying the medical images in an Internet browser and receiving a request to print at least one selected medical image; and a processor coupled to a memory for storing a plurality of instructions. The processor can be configured for generating a base model that includes at least one page required to print the at least one selected medical image, generating a printable model by, for each of the at least one selected medical image, rendering that selected image to an image element of a page of the base model; and transferring the printable model to a model printable by the Internet browser.

    摘要： A short axis in a 3 dimensional image of a lesion is determined starting from voxels defining the long axis and voxels in the plane of the long axis. Voxels within the plane of the long axis are projected perpendicularly onto the long axis and receive an identifier indicative of the region on the long axis onto which they are projected. Distances between points (projected sub-voxels) in pairs of points within the same range and within adjacent ranges are evaluated in order to determine the longest distance.
