Frameless stereotactic targeting devices: technical features, targeting errors and clinical results.
Brain biopsies (BB) and depth electrode placements (DEP) are increasingly performed using frameless stereotactic targeting devices. This paper is intended to provide a comprehensive review of the technical features, targeting errors and clinical results. ⋯ Frameless stereotactic targeting devices may reach targeting errors and clinical results comparable with standard frame-based stereotaxy. Advantages and disadvantages of different devices should be acknowledged to ensure optimal technical performance.

Central venous catheterization is a procedure in which a doctor inserts a catheter into a patient's vein for transfusions. Risks of this procedure include bleeding from the puncture of blood vessels and pneumothorax caused by pleural puncture. To avoid these and other risks, physicians are required to ensure that the needle is inserted securely and that it stops within the vein. ⋯ The feasibility of this system was demonstrated in our experiments. Further studies, such as in vivo experiments, are required.
