P1C-1 Evaluation of Material Parameters of PVA Phantoms for Reconstructive Ultrasound Elastography

The real-time ultrasound elastography system presented in Pesavento, A. et al., (1999) allows the use of elastography in a clinical study for the early detection of prostate cancer during conventional transrectal ultrasound examinations. Since tumors often consist of hard tissue structures, imaging the elastic properties promises to increase the ability to detect prostate cancer. In the frame of reconstructive elastography it is important to understand more about material properties and boundary conditions. Thus in freehand elastography, the compression is manually induced by the conducting physician leading to unstable strain image sequences. Therefore we present in this work a new designed phantom with known target E-modulus and boundary data to help physicians get used to real time elastography systems and to solve the forward and inverse problems respectively.
