It has compact structure and little volume. By adjusting spring force and improving sensitivity, the probe can be used in CMM. Errors of the probe are analysed. Performances of the probe are verified by test of measuring force, verification of precision of single axis and plane precision.展开更多

A 61 year-old Japanese man had a 3.5 cm in diameter HCC nodule in the liver S3 region. We applied the Live 3D ultrasonography during RFA therapy with a cool-tip needle electrode. The echo guidance facilitated an accurate approach for the needle puncture. The guidance was also useful for confirming, whether an adequate safety marging for the nodule had been obtained. Thus new Live 3D ul-trasonography echo technique appears to provide safe guidance of RFA needles via accurate targeting of HCC nodules, thereby allowing real-time visualize- tion when combined with echo contrast.展开更多
