According to preliminary results subarachnoidal space widening can be differentiated with both techniques, but the true nature and its chemical and physical properties still remain uncertain preoperatively. Tumors such as meningeomas, gliomas as we

Differentiation with malignant peripheral nerve sheath tumor is impossible. Cystic spaces within the lesion are as well detected as by CT or MRI. New B-mode equipment wi

The operator can easily judge the axis and can precisely estimate the axial length in a short period of time. Furthermore using this method we can achieve 95% reliability with but a sing

Clinical usefulness of linking biometry systems to personal computersgy. The benefits of using a commercial biometry unit as an acquisition device with a separate computer to process biometric data according to specific applications were pointed out. Based on this approach a clinical biometry system with the GBS as ultrasonic component was introduced. By linking the
