Subtraction Technique in Intravenous Aortography
Radiology, 1977 Excretory urography using the subtraction technique (100 ml of 60% urographic media injected in 10-12 seconds) demonstrated the aorta and its major branches well enough to prove useful clinically. The method is fast and graphic, and risk seems no greater than that associated with the standard urographic examination.

BeppoSAXLECS background subtraction techniques [PDF]
Astronomy and Astrophysics Supplement Series, 1999 We present 3 methods for the subtraction of non-cosmic and unresolved cosmic backgrounds observed by the Low-Energy Concentrator Spectrometer (LECS) on-board BeppoSAX. Removal of these backgrounds allows a more accurate modeling of the spectral data from point and small-scale extended sources.
