摘要
A micro X-ray tube (1) with exchangeable anode or anticathode material, is used to project X-ray beam towards central portion of object (3) to be imaged. Edge subtraction of images having energies higher and lower than the absorption edge of a contrast element, is performed for resolution improvement.
