METHOD FOR GENERATING QUANTITATIVE IMAGES OF THE FLOW POTENTIAL OF A REGION UNDER INVESTIGATION
First Claim
1. A method for generating images representatives of the flow potential of a permeable body comprising the following steps:
- providing a first sequence of digital images of the body perfused by a fluid at a rest condition;
extracting at least one first quantification image of the spatial distribution of flow of said fluid in said body at said rest condition, said at least one first quantification image being defined by pixel values having an appearance scale univocally correlated to a parameter representative of the perfusion at said rest condition;
providing a second sequence of digital images of the body perfused by the fluid at a stress condition, wherein at such stress condition the perfusion is forced to be increased with respect to the rest condition;
extracting at least one second quantification image of the spatial distribution of flow of said fluid in said body at said stress condition, said at least one second quantification image being defined by pixel values having an appearance scale univocally correlated to a parameter representative of the perfusion at said stress condition; and
combining the two quantification images to obtain at least an image defined by pixel values having an appearance scale univocally correlated to a combination of corresponding pixels of the two quantification images.

Abstract
The invention relates to a method for generating images representative of the flow potential of a permeable body. The following steps are part of the disclosed method. First, providing a first sequence of digital images of the body perfused by a fluid at a rest condition. Then extracting a first quantification image of the spatial distribution of flow of the fluid in the body at the rest condition, the first quantification image being defined by pixel values. Next, providing a second sequence of digital images of the body perfused by the fluid at a stress condition. Then extracting a second quantification image of the spatial distribution of flow of the fluid in the body at the stress condition, the second quantification image being defined by pixel values. Then, combining the two quantification images to obtain an image defined by pixel values.
