In this paper, we present a novel robotic assistant dedicated to otologic surgery for an implantable hearing aid system, which is a procedure involving drilling into the lateral skull of the patient. This compact and flexible miniature robot is designed so as to fulfill the requirements of precise bone drillings for hearing aid implantation. It is built from an original five degree-of-freedom (DOF)...
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...
In order to obtain quantitative mechanical properties of tissue non-invasively, we propose in this work an inverse approach by which the spatial distribution of the relative shear modulus of tissue can be estimated from the measured axial and lateral deformation using angular insonifications. Measurements on PVA phantoms and the procedure to obtain the shear modulus are described.
