Ultrasound Imaging



Our research works concern the physical and signal interaction for the ultrasound imaging systems and the development of methods allowing to extract the relevant parameters of the images / signals with the aim of characterizing biological tissues.

The control of the device of acquisition allows us to act on the image formation process. The radio frequency (RF) images and customized images are beamformed with the raw signals directly provided by the ultrasound probe. The image formation is so adapted to the methods which we develop. Mutually, the methods take into account the spatiotemporal impulse response of the imaging system and the beamformed image properties.

The methods which we develop lean on physical models to estimate the parameters of elasticity, viscosity or non linearity of biological media. Complementary approaches allow the estimation of the geometrical and statistical characteristics of ultrasound images or image sequences to recover the properties of the biological media. Whenever possible, the methods are developed to operate in real time, ie the rate of acquisition of images by the system and are extended to 3D data.

The experimental investigations are performed with our ultrasound imaging devices.
