Modified Subtraction Technique for Neuroradiology

Radiology, 1973
The authors suggest modifying the standard subtraction technique for use in neuroradiology by using the most informative film in the venous phase as the mask. The anatomical relationships between arteries and veins are shown on one film, while the effect of space-occupying lesions is accentuated using this technique.

Improved Contrast in Subtraction Technique

Radiology, 1970
The authors describe a rapid, reliable method of second-order subtraction in which contrast is improved by the addition of a final exposure on high-contrast photographic film. Such films readily lend themselves to copying for slides and publications, with negligible cost of materials.

A novel spectral subtraction technique for cognitive radios

open access: yes2013 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2013
In the past a lot of work has been done to remove noise from speech. Most of the presented techniques were derived from Boll's spectral subtraction technique. Roughly speaking the spectral subtraction techniques consists of estimating the noise power during the periods when no speech is present and subtracting this estimate of the noise power from the ...
