Robert C. Gemperline - Algonquin IL, US

Assignee:

GE Medical Systems Information Technologies, Inc. - Milwaukee WI

International Classification:

G06K009/36

US Classification:

382240, 382232

Abstract:

Image data is compressed by decomposing the image data into a plurality of resolutions or sized by wavelet decomposition, followed by compression of the resulting data sets. Adaptive Huffman code compression is optimized for compressing the data sets, predictive errors for a low frequency band and the wavelet transformed values for high frequency bands. The image data is thus compressed losslessly and in multiple resolutions such that desired resolution images can be reconstructed and transmitted in accordance with available-bandwidth and viewing capabilities.

International Classification:

A61B 6/03

US Classification:

378 4, 378 8

Abstract:

A method of performing a colon exam includes obtaining at least two initial Computed Tomography (CT) datasets, extracting colon automatically from the CT datasets, synthesizing views of the extracted colon, displaying a plurality of obtained and synthesized views of the colon simultaneously, and synchronizing the views.

09/996320

Saad A. Sirohey - Pewaukee WI, US

Assignee:

GE Medical Systems Information Technologies, Inc. - Milwaukee WI

International Classification:

G06K 9/36
G06K 9/32

US Classification:

382240, 382299

Abstract:

The present technique selectively handles image data, which is decomposed into a plurality of resolution levels. The image data may be retrieved in order of progressively higher resolution levels for display in a viewport. Initially, the image data may be displayed in the viewport at a relatively lower one of the plurality of resolution levels. As a user desires higher resolution displays of all or part of the image, one or more of the progressively higher resolution levels may be retrieved and scaled to fit the viewport. Accordingly, the present technique handles the data more efficiently by accessing the image data in blocks corresponding to the plurality of resolution levels, rather than accessing the entirety of the image data. A scaling threshold also can be used to signal the need for a next higher level of the plurality of resolution levels.

International Classification:

G06K 9/00

US Classification:

382128, 382294, 382277

Abstract:

Certain embodiments of the present invention provide a system and method for automatically synchronizing multiple images. Multiple image sets of a single object are converted into a one dimensional data stream used to synchronize multiple image sets. A common reference point is located in the image sets. Various landmarks of the object are also located in the image sets. Corresponding landmarks among the image sets are noted. Distances from landmarks to the reference point and distances between landmarks are determined. Locations of the landmarks in relation to each other and in relation to the reference point are used to locate landmarks in another image set that correspond to landmarks in a selected image set. A first location in an image set may be identified using a first indicator. A second indicator corresponding to the location of the first indicator may then be determined in another image set.

International Classification:

G06K 9/00

US Classification:

382128, 382203, 378 28

Abstract:

Certain embodiments of the present invention provide a system and method for structuring dynamic data from a plurality of images. Certain embodiments include accessing an image data set including data representing a plurality of images, determining a dynamic or functional attribute in the image data set, associating the dynamic or functional attribute with a lexical attribute from a lexicon, and storing the lexical attribute and an associated code. The lexical attribute and associated code may be stored in a database and/or a structured report, for example. The lexicon may be modified to accommodate attributes and medical terminology. Attributes relate to a feature and/or a region of interest in the image data set.

International Classification:

G06K 9/36

US Classification:

382240

Abstract:

The present technique addressably handles image data, which is decomposed and tessellated into a plurality of tessellated sub-band blocks. The tessellated sub-band blocks may be addressed by an array of indices, which identify specific data blocks of the image data by decomposition level and spatial coordinates of the tessellated sub-band blocks. Accordingly, a desired region of the image data at multiple resolutions can be identified and individually handled for storage, transmission, retrieval, and display. The desired region also can be reference marked based on the array of indices.
