Noninvasive X-ray imaging of nanoscale three-dimensional objects, e. g. integrated circuits (ICs), generally requires two types of scanning: ptychographic, which is translational and returns estimates of complex electromagnetic field through ICs; and tomographic scanning, which collects complex field projections from multiple angles.

X-ray ptychography allows for large fields to be imaged at high resolution at the cost of additional computational expense due to the large volume of data.
