In vivo examination of human lipomas with freehand elastography - Preliminary results

Abstract

In the context of ultrasound elastography, we recently developed a 2D strain estimation method to image the deformation of a medium during its compression with the probe. This technique was proved to provide good-quality strain images with data acquired in a freehand configuration on elastography-dedicated phantoms and ex vivo dog tissue lesions. In this study, the application to in vivo human benign tumors is presented. The initial results obtained demonstrate that our method is able to provide easily interpretable deformation images in clinical conditions.
