Abstract: In this paper, a novel quasi-static 3D ultrasound elastography method based on a low degree of freedom (DoF) linear scanning mode is proposed. A linear slide rail is used to rigidly control the scanning trajectory and by appropriately adjusting the height of the probe, the pre-and post-compression ultrasound radio-frequency data are acquired sequentially. Finally, a 3D quasi-static ultrasound elastography system is developed using a dynamic programming method and 3D strain imaging. Experiments demonstrate that the system can be easily manipulated, and can accurately obtain the 3D strain distribution of an elasticity ultrasound phantom.
