Different studies in X-ray microscopy have arrived at conflicting conclusions about the dose efficiency of near- and far-field imaging approaches. X-ray far-field ptychography is compared with near-field holography and near-field ptychography in computer simulations. All three methods are highly dose efficient, with far-field ptychography offering slightly better low-dose imaging characteristics.

近、远，无论您身在何处：全息和叠相相干成像剂量效率的模拟

X 射线显微镜的不同研究对于近场和远场成像方法的剂量效率得出了相互矛盾的结论。X 射线远场叠印术与近场全息术以及计算机模拟中的近场叠印术进行了比较。所有三种方法都具有很高的剂量效率，远场叠层成像技术提供稍好的低剂量成像特性。
