single entry
5.The general method to implement single access point in cluster is transmitting the incoming requests to real servers by one front-end node as a gateway, which can well resolve the single entry. But it is easy to lead to single point of failure and difficult to extend the performance of the gateway.
10.Methods Target localization and dose plan were done by stereotactic MR(1.5 Tesla) study and Leksell Gamma Plan. Single 4 mm collimator with central dose 70 to 90 Gy and 50% isodose line conforming were directed at the sensory root of trigeminal nerve entry zone of pones for 65 patients with non tumor related trigeminal neuralgia, and for 10 patients with tumor related trigeminal neuralgia.
