Method for computer-aided-, non-destructive examination of e.g. teeth in dentistry, involves determining materials in object based on reconstruction steps of optimization problem per volume element by computation of probability vector

摘要

The method involves attaching surface elements (6) at a position in a projection surface (5) and two-dimensional projections based on a surface data value. Volume data values are determined based on the projections such that volume elements (8) represent a three-dimensional image of an object (3). A discrete number is assigned to volume elements, where the number represents a material of a workpiece and is larger than two. Materials in the object are determined based on global reconstruction steps of an optimization problem per volume element by iterative computation of a probability vector. Independent claims are also included for the following: (1) a computer program product having a set of instructions for executing a method for computer-aided-, non-destructive examination of a three-dimensional object (2) a device for non-destructive examination of an object.
