Reduction of Phase Aberration in a Diffraction Tomography System for Breast Imaging
In the past three years we have developed a diffraction tomography system for research in medical imaging.1,2 The system was designed to address some of the aspects of current medical ultrasound that limit its use in many applications. For example, high-resolution ultrasound is restricted to a small field of view which can make it difficult to locate the area of interest and which does not allow ready comparison of normal and suspected abnormal tissues. As a result, the quality of medical sonography greatly depends on the skill of the operator who must recognize the important images and capture them on film for review by physicians. The findings of sonography are therefore not easily reproduced.
