A high-resolution mandibular tracking system was designed and tested in a freely moving mouse. A sensor unit, which consisted of four small magnetic sensors, was employed to trace small magnet movements in the three-dimensional space. After the sensor's output-to-displacement transformation equations were obtained from a multiple regression analysis of(More)
The purpose of this study was to develop a new method for the quantitative and qualitative measurement of tooth displacement under load and to clarify the relationship between the force system acting on a tooth and a resultant movement. A combination of eight magnetic sensors and a magnet was employed to measure three-dimensional displacement. Two sets of(More)
In the case of extracorporeal shock wave lithotripsy (ESWL), a shock wave-bubble interaction inevitably occurs near the focusing point of stones, resulting in stone fragmentation and subsequent tissue damage. Because shock wave-bubble interactions are high-speed phenomena occurring in tissue consisting of various media with different acoustic impedance(More)
