METHOD FOR CORRECTING THE SCATTERED FLUX IN DIGITAL RADIOGRAPHY IMAGES

摘要

The invention concerns a method for correcting scattered flux energy which consists in: on the basis of a radiography and of a first three-dimensional model of the object, generating a second model of the object adapted to the geometry of the latter; discretising the source energy spectrum and attributing to each zone of said object a mean density value; determining a mapping of the primary flux energy; determining along the source-point path of the primary flux energy mapping a new mean density value for each of the zones and for each source-point path of the detector; obtaining a coherent scatter coefficient and an incoherent scatter coefficient of energy for each path and for each zone; determining the mapping of the scatter energy; determining the mapping of the primary flux energy and obtaining an image of the object.
