Résumé

Statistical analysis is performed on the envelopes of ultrasonic backscattered signals from concentrated human leukemia cell pellet biophantoms. Two statistical distributions (Nakagami and Homodyned-K) are used to assess scatterer concentration. Seven concentrations ranging from 0.006 to 0.30 (corresponding to 3 to 250 scatterers per resolution cell at 25 and 35MHz) are considered. The values of the Nakagami parameter m increase with the number of scatterers per resolution cell but plateaus around 1 for concentrations greater than 0.03, while the Homodyned-K parameter α continued to increase and does not plateau, even if the estimation is less precise.
