F41J 5/24

US Classification:

273383

Abstract:

A remotely-perceptible, impact-indicating target for a projectile, such as a bullet or the like, constructed so as to remotely perceptibly indicate and annunciate very realistically, to a target shooter at a projectile shooting location, the impact of a shot or fired projectile or bullet on a remotely located target in a manner clearly visibly perceptibly indicating not only the hit, but the impact location of the projectile or bullet on the target, by causing the effective expansion in an explosion-simulating manner of a quantity of visibly perceptible target material.

International Classification:

G06T 7/00

US Classification:

382128

Abstract:

The invention relates to a method for automatically determining, on a bone comprising a head portion contiguous to a neck portion, parameters for characterizing a bump deformation on the head-neck junction of the bone from acquired 3D medical image, the method comprising the following steps: i) constructing a 3D surface model of the bone; ii) fitting a sphere on the spherical portion of the head of the bone; iii) determining a neck axis characterizing the neck portion of the bone; iv) determining from the fitted sphere and the neck axis, a clock face referential on the head of the bone rotating around the neck axis; v) determining a 3D curve on the 3D surface model characterizing the head-neck junction of the bone; vi) determining, from the 3D curve, the summit of the bump deformation of the head-neck junction of the bone; vii) determining, from said summit of the bump deformation, first and a second parameters (α3D, iMax) characterizing the maximum bump deformation of the head-neck junction of the bone.

International Classification:

G06F 19/26

US Classification:

703 1

Abstract:

The invention relates to a method for real-time determination an optimal corrected surface of a first bone and/or a second bone forming together an articulation, the first and/or second bones presenting an overgrowth deformation, said corrected surface providing a greater range of motion of the articulation, the method comprising the following steps: i) constructing from acquired images of the articulation 3D voxel models of the first bone and the second bone; ii) for each of first and second bone voxel models, constructing a coordinate system defmed by a center and three axes; iii) applying a motion pattern on the coordinate system of the second bone with respect to the coordinate system of the first bone, a motion pattern being a set of contiguous positions of the first or second bone coordinate systems with respect to the other bone coordinate system, the contiguous positions defining a movement of one bone with respect to the other, wherein said motion pattern is initially loaded from a data base of pre-defined motion patterns; iv) determining a resection volume from said motion pattern as being the union of interpenetration volumes of the first or second bone voxel model with the other bone voxel model for each position of the motion pattern; v) determining the optimal corrected surface by virtually removing said resection volume from the first and/or the second bone voxel model.

US Classification:

382131

Abstract:

The invention relates to a method for non-invasive reproducible determination of a corrected surface on a 3D bone surface model constructed from 3D medical image of a bone having a deformation consisting in a bump overgrowth at the head-neck junction; wherein said corrected surface comprises: i) a 3D spherical corrected surface patch on the head portion of said 3D bone surface model, and ii) a 3D smooth transition corrected surface patch on the neck portion of said 3D bone surface model, contiguous to said 3D spherical corrected surface patch; Said corrected surface patches are defined by a set of parameters comprising: iii) at least one first parameter (a*) representing a spherical extent value of said 3D spherical corrected surface patch, iv) and a set of at least one second parameter, said set determining the 3D correction boundary of said corrected surface patches, such that said corrected surface patches are continuous with said 3D bone surface model along said boundary.
