Abstract: The invention relates to an apparatus for determining a temporal breast cancer risk (27). This risk is indicative of detecting cancer in a breast within a predetermined time interval after a negative breast cancer detection result that has been obtained by carrying out a breast cancer detection procedure defined by a breast cancer detection parameter. The temporal breast cancer risk (27) is determined based on a) a probability parameter (25) being indicative of a probability of having breast cancer and b) a density parameter (26) being indicative of a density-related property of breast tissue of a breast, wherein the probability parameter (25) and the density parameter (26) have been determined based on a breast image data set (24) of the woman by using an artificial intelligence. The determined risk can be used, for instance, for deciding whether a supplemental examination should be performed immediately or for defining a screening interval.

Abstract: According to various embodiments, a method and system is provided to model geometric properties of garments taking into account the effects of the seams that are created to make the garment for use in computer modeling applications. All the seams in a garment, including overlapping seams and asymetric seamlines, are processed based on geometric operations on 2D models of pieces of fabric from patterns. Working in 2D simplifies folding and stitching. A set of parametric spaces are used to enforce continuity along and across seams. A set of constrained optimizations in 2D and 3D are used to guarantee spacial continuity. Geometries produced can be simulated, providing clothing representations where the mechanical and appearance properties of multi-layer seams are derived automatically by applying geometrical operations and physically-based simulation to fabric pieces.
