Paper Abstract

This paper discusses ptychography, a coherent diffraction imaging technique. Advantages of ptychography with respect conventional imaging techniques for cell visualisation are highlighted and demonstrated using unstained healthy and tumorous mouse cells as the object under investigation. A novel procedure to automatically refocus a possible slightly out of focus ptychographic data set will be discussed, by which an improved quantitative analysis and discrimination is enabled.
