  • Patent number: 10671659
    Abstract: A system and method for collecting medical image data items. A central processor identifies a new medical image data file on a remote image storage memory. The central processor determines that the new medical image data file is a completed file and copies the completed file to a central storage memory. The central processor determines an expected set of files corresponding to the medical image data file that defines a medical image data item. The central processor determines that each of the medical image data files in the expected set have been copied to the central storage memory. The central processor then generates an indicator that the medical image date item is available on the central storage memory.

  • Patent number: 10372876
    Abstract: A system and method for providing breast image data. A transmission request is transmitted from a workstation to an imaging server with identifying characteristics for a mammography image. A pre-determined breast window for the mammography image is identified. An unprocessed image stored on the server that corresponds to the mammography image is identified, and breast image data can be determined for unprocessed image. The breast image data includes a breast window image that can be determined by applying the pre-determined breast window to the unprocessed image. The breast image data is transmitted to the clinician workstation, and the breast window image is displayed at the clinician workstation.

  • Patent number: 10127683
    Abstract: 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.
