Abstract

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.
