| subtraction | 1. The act or operation of subtracting or taking away a part. 2. <mathematics> The taking of a lesser number or quantity from a greater of the same kind or denomination; an operation for finding the difference between two numbers or quantities. 3. The withdrawing or withholding from a person of some right to which he is entitled by law. Thus the subtraction of conjugal rights is when either the husband or wife withdraws from the other and lives separate without sufficient reason. The subtraction of a legacy is the withholding or detailing of it from the legatee by the executor. In like manner, the withholding of any service, rent, duty, or custom, is a subtraction, for which the law gives a remedy. Origin: L. Subtractio a drawing back. See Subtract, and cf. Substraction.

| subtraction technique | Combination or superimposition of two images for demonstrating differences between them (e.g., radiograph with contrast vs. One without, radionuclide images using different radionuclides, radiograph vs. Radionuclide image) and in the preparation of audiovisual materials (e.g., offsetting identical images, colouring of vessels in angiograms). (12 Dec 1998) |
| angiography, digital subtraction | A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitised image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. (12 Dec 1998) |

| digital subtraction angiography | Computer-assisted roentgenographic angiography permitting visualization of vascular structures without superimposed bone and soft tissue density; images made before and after contrast injection allow subtraction (separation and removal) of opacities not enhanced by the contrast medium. Other image-processing can be performed. Contrast material may be injected intravenously or in lower-than-usual amount intra-arterially. (05 Mar 2000) |

| subtraction |
The operation used to find the result of taking away something from a group, or finding parts of a whole. Subtraction is indicated by the minus sign (-). Subtraction is the opposite of addition. When a number is subtracted from another number, the resulting number is smaller than the minuend.
