Abstract: Image data and E-mode images used in ultrasonic elasticity imaging may be automatically evaluated for quality to provide a single value used as operator feedback or for automatic selection of images for averaging or animation.

Abstract: In an apparatus and method for treating an aneurysm, a flow control member is positioned within a blood vessel at least in part upstream of an aneurysm and extending radially inward of the blood vessel wall into the flow path of blood flowing within the blood vessel. The flow control member alters the blood flow path within the blood vessel upstream of the aneurysm to inhibit blood flow to the aneurysm. A retention member may be positioned within the blood vessel at least in part upstream from the aneurysm and having an outer surface engageable with the blood vessel wall. In such an instance, the flow control member is retained by the retention member and extends radially inward of the blood vessel wall upstream from the aneurysm.

Abstract: An elasticity measuring system determines tissue displacement between a pre-deformation and post-deformation image by a matching process using a cost function accepting as its arguments continuity of the tissue motion and correlation of the tissue in making the block matching. The invention allows the selection among different cost functions for different imaging situations or tissue types, to provide improved displacement calculations using a priori knowledge about the tissue and structure of tissue interfaces or information derived during the scanning process.

Abstract: The determination of axial and lateral displacement in a material subject to compression is determined by fitting a multi-dimensional model function to the match between corresponding portions of the material in two states of compression. In one embodiment, iso-contour lines in a correlation between a reference kernel and a target kernel are fit to an ellipse whose center defines the maximum correlation and hence the displacement.

Abstract: The identification of preferred seed calculations used to guide the determination of displacement vectors in elasticity imaging may evaluate seeds using a combination of a measure of the similarity of the data of the seed in pre- and post-compression data and continuity of the data in a path in the neighborhood of the seed. This dual evaluation helps avoid downstream error propagation.

Abstract: A method for producing a computational flow dynamics model for assessing the efficacy of the deployment of a flow-diverting device in a blood vessel of a patient is provided. Image data of the patient is acquired with a medical imaging system, from which images depicting the blood vessel are reconstructed. A pre-treatment blood vessel model is generated by segmenting the reconstructed images. This pre-treatment blood vessel model is then used to generate a post-treatment, or post-deployment, model of the blood vessel. A post-deployment model of the flow-diverting device is generated and used together with the post-treatment blood vessel model to generate a computational flow dynamics model.
