摘要： Because of the increase of the obesity related diseases, it is desirable to be able to detect a fatty liver and quantify the content in fat for the fatty liver. Known methods are biopsy and magnetic resonance imaging. However, biopsy is an invasive method and magnetic resonance imaging is a complicated method to carry out. The inventors propose a new ultrasonic method, which is more compliant with a regular control of the content in fat for the fatty liver for a subject. This method notably relies on a smart exploitation of the coherence properties of ultrasound pulses applied to the liver. This method has already been validated on sane subjects as providing accurate measurements, notably for fat content.

摘要： The invention relates to a method for obtaining a numerical model, the numerical model associating at least one objective measurement to a subjective sensation, the method comprising the steps of: a) imaging the at least one area of the brain by using unfocused waves produced by a transcranial ultrasound probe (20), to obtain at least one acquired image of the activity of the area, b) evaluating a physical quantity representative of the activity of the at least one area based on the acquired images, to obtain at least one objective measurement, c) obtaining from the subject at least one numerical value representative of a subjective sensation, and d) determining the numerical model by using the obtained objective measurement and the obtained numerical value.

摘要： The present invention aims at improving the Doppler imaging of a biological sample comprising blood. For this, it is proposed a method for imaging a biological sample (10), the sample (10) comprising blood (14) comprising diffusors and solid tissue (16), the method comprising obtaining observation, each observation being characterized by a different point spread function associating a signal to each location of the region of interest, the signal comprising a first contribution representative of the diffusors of blood vessels within the location, a second contribution representative of the tissue diffusors and a third contribution representative of blood signal associated to blood diffusors outside of the location, and estimating, for each location, the blood flow by using a statistical analysis.

摘要： Method for functional imaging of the brain, comprising the following steps: (a) a brain is imaged by ultrasound imaging in order to obtain a vascular image to be studied (IVO), (b) the vascular image to he studied (IVO) is compared automatically, by shape recognition, with a cerebral vascular atlas (AV), and the vascular image to be studied (IVO) is thus located in the cerebral vascular atlas (AV), (c) a cerebral functional atlas (AF) corresponding to said cerebral vascular atlas (AV) and comprising cerebral functional zones (1c) located in this cerebral vascular atlas (AV) is used in such a way as to identify cerebral functional zones (1e) on the vascular image to be studied (IVO).
