摘要： A method for determining a flow rate and/or a concentration of particles of a fluid flowing in a chamber, which includes the steps of: producing an ultrasound beam of a given frequency with a first transducer such that all fluid components traveling through an intersection region between the ultrasound beam and the chamber are insonated by the first transducer; receiving Doppler-shifted ultrasound signals generated by the fluid components in the insonated region of the chamber with a second transducer; acquiring the ultrasound signals received by the second transducer during an acquisition time; obtaining a Doppler Power Spectrum of the acquired ultrasound signals; and determining the flow rate and/or the concentration of particles of the fluid by adjustment between, on the one hand, the obtained Doppler Power Spectrum and, on the other hand, a model of the Doppler Power Spectrum.

摘要： An imaging method including: a) acquiring N successive positron emission tomography (PET) low resolution images Γi and simultaneously, N successive Ultrafast Ultrasound Imaging (UUI) images Ui of a moving object; b) determining from each UUI image Ui, the motion vector fields Mi that corresponds to the spatio-temporal geometrical transformation of the motion of the object; c) obtaining a final estimated high resolution image H of the object by iterative determination of a high resolution image Hn+1 obtained by applying several correction iterations to a current estimated high resolution image Hn, n being the number of iterations, starting from an initial estimated high resolution image H1 of the object, each correction iteration including at least: i) warping the estimated high resolution image Hn using the motion vector fields Mi to determine a set of low resolution reference images Lni; ii) determining a differential image Di by difference between each PET image Γi and the corresponding low resolution reference image Lni; iii) warping back the differential images Di using the motion vector fields Mi and averaging the N warped back differential images to obtain a high resolution differential image; iv) determining the high resolution image Hn+1 by correcting the high resolution image Hn using the high resolution differential image; d) applying the motion vector fields Mi of each UUI image Ui to the final high resolution image H.

摘要： The invention relates to a method for determining at least one property of an object, the method comprising a step of: a) obtaining first data relative to the object by an ultrasound imaging technique imaging the object at a frame rate superior to 300 Hz, characterized in that the method further comprises a step of: b) obtaining second data relative to the object by imaging the object with at least one of a X-ray and a γ-ray, and c) determining the at least one property of the object based on the first data and the second data.
