High resolution beamforming for Ultrasound Localization Microscopy (ULM)
Ultrasound localization microscopy (ULM) is an imaging method that provides a map of vessels with micrometer resolution. It consists of tracking ultrasound contrast agents over time on ultrasound images. The three main steps are: detection of microbubbles by reducing the tissue signal, their localization with sub-wavelength accuracy and tracking of their displacement. In parallel, high-resolution imaging algorithms are used to obtain ultrasound images that would allow the ULM algorithm to exploit more information present in the data. They also allow to filter the tissues, an asset for the detection of contrast agents. The objective of the thesis is then to evaluate the effect of the different methods of these imaging algorithms on the ULM, with a particular attention on the trade-off between acquisition time and contrast agent concentration.
