Abstract: A new method is introduced able to track the motion of a thin object, e.g. a wall, from a series of digital field data (e.g. images) in order to analyze field information corresponding to the moving position of the object. The method is based on the extraction of M-mode images where the wall can be identified and the wall properties can be extracted and analyzed. The digital implementation of the method into electronic equipments improves the quality of the information that can be extracted from field data and the potential diagnostic capability when applied to echographic medical imaging.

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.

Abstract: A new method is introduced to evaluate the flow through a constriction based on Doppler data and the principle of mass conservation. This principle, properly inserted within a combination of data rearrangements allows the extraction of the complete velocity field and the optimal evaluation of the flow through the constriction. The digital implementation of the method into electronic equipments, like an echographic machine, gives an additional capability of quantifying specific valvular flows and improves diagnostic potential.

Abstract: A method for generating time independent images of moving objects with the image information being related to properties of the moving objects represented by sequences of digital images. The images are transformed into a series of space-time representations of the image data. A function is derived from the space-time representation images that approximates the object motion and is used to create time independent images of the moving objects.
