Dynamic transfer of three-dimensional image data

摘要

A method for transferring volumetric image data from a server to at least one client comprising: transforming said volumetric images into a hierarchical representation comprising a plurality of coefficients, said hierarchical representation comprising a plurality of levels of essentially non-redundant data, wherein a level of said hierarchical representation comprises transform data sufficient to reconstruct said images at a resolution corresponding to said level; partitioning said coefficients into a plurality of voxels, each voxel comprising “n” coefficients in a horizontal direction, “m” coefficients in a vertical direction, and “P” coefficients in a depth direction; requesting, from a client to a server, transform data in the form of voxels from one or more levels of said hierarchical representation necessary to reconstruct at least a portion of said source volume; transferring, from a client to a server, a request for coefficients of at least a portion of said volumetric image; transferring, from said server to said client, at least one voxel in response to said request; and reconstructing, at said client, volumetric views of said volume images from said transferred at least one voxel.

1. An image processing system comprising:
a server including a processor and storage configured to store a unitary pyramidal representation of a volumetric image, the unitary pyramidal representation comprising a set of coefficient voxels and having hierarchical levels where each successive level adds information for providing increased spatial resolution, and each coefficient voxel corresponds to a defined three-dimensional spatial region of the volumetric image and to a selected level of the hierarchy; a network interface configured to convey selected coefficient voxels via a network responsive to a request for imaging data of the volumetric image corresponding to a selected spatial region and to a selected spatial resolution; and a client including a processor, storage, and a display, the client configured to receive from the server the conveyed selected coefficient voxels and to reconstruct and show on the display an image reconstructed from the received coefficient voxels corresponding to the selected spatial region and the selected spatial resolution; wherein the client further includes at least one user input device and is configured to execute an image navigation and processing application program operating in conjunction with the display and the at least one user input device, the executing image navigation and processing application program selecting the spatial region and the spatial resolution, the client further configured to generate and send to the server a client request identifying the selected spatial region and the selected spatial resolution or identifying coefficient voxels corresponding to the selected spatial region and the selected spatial resolution.
