Publication number: 20220192639Abstract: An innovative method is disclosed for merging images of an organ in vivo captured through a first imaging technique and a second imaging technique, this latter using an endocavity ultrasound probe inserted into a cavity associated with the organ under investigation. For superimposing the images on one another with greater accuracy, the images captured through the first imaging technique, that is different than the ultrasound technique, a dummy probe is inserted into the cavity associated with the organ under investigation. The dummy probe may be applied both using prior art biplane endocavity probes and innovative electronic scanning endocavity probes. Therefore, two types of endorectal probe are described: a biplane probe, that shall be rotated and translated for capturing biplane images; and a new electronic scanning ultrasound probe delivering the two-dimensional images for the merging without the need for moving the endocavity probe.Type: ApplicationFiled: April 16, 2020Publication date: June 23, 2022Inventors: Leonardo MASOTTI, Luca BRESCHI

Patent number: 7509861Abstract: The method decomposes the radio frequency signal into sub-bands by filtering, for example with a time-frequency transform. From the coefficients acquired through decomposition a matrix of spectral coefficients is obtained, from which local estimators are obtained, constituted in particular by the coefficients of the interpolating polynomials. The statistical distribution of the local estimators is evaluated in windows overlaid on the ultrasound frame. The conformation of the distribution histograms of the spectral coefficients provides a parameter which, combined with the local estimators, provides weighted local estimators, which contain spectral information useful in the identification of specific structures in the organ subjected to ultrasound analysis.Type: GrantFiled: October 5, 2004Date of Patent: March 31, 2009Assignees: Actis Active Sensors S.r.l., Esaote S.p.A.Inventors: Leonardo Masotti, Elena Biagi, Simona Granchi, Luca Breschi

Publication number: 20040193056Abstract: What is described is an echographic examination method, in which an echographic contrast medium or agent, injected into a blood vessel and comprising a plurality of microbubbles, is sent by means of the blood circulation to a part of a living body under investigation and said part is struck by an ultrasonic excitation signal at an excitation frequency (f0), and in which the microbubbles struck by the ultrasonic excitation signal generate an echo signal at a frequency different from the excitation frequency, said signal being used to, generate an image. The excitation signal exerts a pressure of 30 kPa to 1 MPa on said microbubbles, the microbubbles emitting a stable signal at not less than one subharmonic of the excitation frequency, said stable signal being processed to generate images.Type: ApplicationFiled: March 25, 2004Publication date: September 30, 2004Inventors: Elena Biagi, Leonardo Masotti, Luca Breschi, Marco Scabia, Simona Granchi
