Abstract (en)
[origin: WO2017211831A1] Method for measuring cardiac output using an ultrasound apparatus, wherein: a plurality of images of an area of the heart where a contrast agent has been injected is acquired by the ultrasound apparatus, at different times; values of the intensity of the area are extracted from the images; and the cardiac output is calculated from the value given to at least one parameter (k) of a reference function, adjusted so that said function best describes the changes in the intensity values measured.
