Quantitative Imaging of Young’s Modulus of Soft Tissues from Ultrasound Water Jet Indentation: A Finite Element Study

Figure 2

Model of the water jet indentation in ANSYS. The upper part represents fluid domain, which included a long water pipe with 60 mm in length, a bubbler, and a nozzle. To make the outlet clearer, an enlarged part was displayed at the right bottom. Radius of inlet was 1 mm and outlet 0.85 mm. Point 1, the upper point of inlet, and Point 2, the central point of outlet, were set as two monitoring points. The lower part represents solid domain. Diameters of the tissue phantom was 25 mm and its thickness was 5 mm.
