Gianni Pedrizzetti, Giovanni Tonti, Emidio Marchese:
Method for generating time independent images of moving objects.
Esaote S p A, AMID
June 21, 2005:
US06909914
(8 worldwide citation)

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 f ...

Method of tracking position and velocity of objects borders in two or three dimensional digital images, particularly in echographic images.
Esaote S p A
March 11, 2008:
US07343031
(7 worldwide citation)

A method of tracking position and velocity of objects' borders in two or three dimensional digital images, particularly in echographic images. A sequence is acquired of at least two consecutive ultrasound image frames of a moving tissue or a moving object. The frames are separated by a certain time ...

M-tracking for space-time image.
Esaote S p A
August 3, 2010:
US07766837

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 ...

Measurement method of time varying events in a target body and a method for displaying measurement data of different parameters of a target in which time dependent events occur.
Esaote S p A
March 27, 2012:
US08142358

A measurement method of time varying events in a target body, including the steps of (a) providing time dependent measurements signals of parameters of the time varying events in the target body, (b) providing ecographic M-mode image data whose spatial direction is along scan-lines or along a line o ...

Gianni Pedrizzetti, Giovanni Tonti:
Method for estimating tissue velocity vectors and tissue deformation from ultrasonic diagnostic imaging data.
Esoate S p A, Amid
October 4, 2011:
US08029444

A method is disclosed for estimating tissue velocity vectors and oriented strain from ultrasonic diagnostic imaging data. Reference points are defined from evaluation of image data derived from reflected ultrasonic beams in order to determine the direction of motion and the velocity vector of the re ...

Gianni Pedrizzetti, Emidio Marchese, Giovanni Tonti:
Flow-rate conservative doppler estimate.
Esaote S p A, Amid
September 18, 2007:
US07270635

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 fl ...

Method of transforming a doppler velocity dataset into a velocity vector field.
Tomtec Imaging Systems, Amid S R L
October 14, 2014:
US08858437

A method and device for transforming a Doppler velocity dataset into a velocity vector field, the including: (a) providing a 2D or 3D Doppler velocity dataset, acquired by means of 2D or 3D ultrasonography from an object; b) calculating a velocity vector field by assuming the velocity at each point ...
