Retrospective correction of inhomogeneities in radiographs |
摘要 |
Several methods for retrospective correction of intensity inhomogeneites in digital diagnostic radiation images are presented. The methods are based on the correction of a digital image representation by means of a bias field. The bias field is deduced from the digital image representation of the diagnostic radiation image. <IMAGE> |
