Pseudocoherent phase-contrast imaging method with variable focus depth: an effective tool for low-contrast radiological image analysis

摘要

New method of low-contrast radiological images analysis is presented. The key method's idea is based on representation of an observed image as the complex envelope of a hypothetical pseudocoherent wave field. The following analysis is based on the ideas of the virtual computer synthesis with using procedures for wave equation inversion and controlled interferometric synthesis. The method provides significant increase in the sensitivity and space resolving power of low-contrast images analysis.
