A system for inducing tissue vibration for magnetic resonance elastography is described. The system includes a passive actuator component, a first hose, a second hose, and a driving component. The passive actuator component is positionable proximate to a target tissue and includes a linearly movable piston assembly enclosed in a housing. The driving component includes a fluid pumping system and is configured to alternatingly pump a fluid through the first hose and through the second hose. When fluid is pumped through the first hose, the piston assembly moves in a first linear direction and, when fluid is pumped through the second hose, the piston assembly moves in the opposite direction. The alternating linear movement of the piston assembly induces vibration in the target tissue.

A method, system, computer program product, and computer readable media for a semi-automated surface extraction approach to delineating an object of interest (OOI) from 3-D medical image data sets. This approach is imaging modality independent and results in enhanced displays of blob-like anatomies, including internal organs (e.g., cardiac chambers, liver) or disease processes (e.g., tumor masses). In an embodiment of the method: (I) the user provides multiple representative points located on the surface of the OOI using a Multi-Planar Reconstruction (MPR) tool; (2) those Cartesian points are translated into polar coordinates (each 3-D point is represented via two angles and a height), which uniquely define the surface points for a radial object, (3) a Radial-Basis Function (RBF) interpolator, with a Thin Plate Spline (TPS) radial function, finds the height function for the polar domain, and (4) polar domain representation of the OOI surface is converted back to Cartesian coordinates.

A method for segmenting tubular structures in digital medical images includes extracting a subregion from a 3-dimensional (3D) digital medical image volume containing a vessel of interest, identifying potential vessel centerpoints for each voxel in the subregion by attaching to each voxel a tip of a 3D cone that is oriented in the direction of the voxel's image gradient and having each voxel within the cone vote for those voxels most likely to belong to a vessel centerline, selecting candidates for a second vote image that are both popular according to a first vote image, as well as being consistently voted upon by a radius image, reconfiguring the subregion as a graph where each voxel is represented by a node that is connected to 26 nearest neighbors by n-link edges, and applying a min-cut algorithm to segment the vessel within the subregion.
