Abstract: A system and method is disclosed for facilitating the acquisition of medical images used as part of a clinical trials process by requiring Imaging Centers to compete with each other to supply the images. Agreements between the Sponsor and a plurality of Imaging Centers stipulate that the Sponsor is only required to accept a certain total number of medical images and is free to reject any medical images that either do not comply with the protocol, or which exceed the total number of medical images required for the study. This motivates the Imaging Centers to quickly obtain and transmit to the Sponsor high quality medical images that meet the basic requirements outlined in the clinical study protocol, since images are accepted and compensated for by the Sponsor on a first-come, first-served basis. A system for implementing this method is also disclosed.

Abstract: Providing information representative of an image in an interactive visualization system includes selecting a current image from a stream of images, evaluating context information within the visualization system, and determining representative information for the current image on the basis of the context information.

Abstract: A seed point is selected inside a structure that is to be segmented in image data. An adaptive model is defined around the seed point, and a preprocessing filter is applied only within the bounding region. A presegmentation of the preprocessed result is performed, and the bounding region is expanded if necessary to accommodate the presegmentation result. An adaptive model for post-processing may be used. The model is translated, rotated and scaled to find a best fit with the pre-segmented data. Additional models can be grown based on testing performed on points on a perimeter of previous models to improve the segmentation of an object.

Abstract: An input processor receives a plurality of different first query messages in a corresponding plurality of different formats. A repository includes stored data elements in a first storage data structure. An intermediary processor automatically: parses the plurality of first query messages to identify requested data elements; maps the identified requested data elements to stored data elements in the first storage data structure of the repository; generates a plurality of second query messages in a format compatible with the repository for acquiring the stored data elements; acquires the stored data elements from the repository using the generated plurality of second query messages; and processes the acquired stored data elements in the plurality of second query messages for output in a format compatible with the corresponding plurality of different formats of the first query messages.

Abstract: NMR imaging data are acquired using a variable phase-encoding gradient. NMR non-imaging data are acquired using fixed phase-encoding, and motion data are derived from such NMR non-imaging data. Gating data are extracted from the motion data and used to select from the NMR imaging data to produce gated image data. The gated image data are used to produce a reconstructed image.
