متن کاملIntegration of CBCT and a Skull Base Drilling Robot
The performance of a Skull Base Drilling Robot is limited in cadaver studies mainly due to registration error in current system. In this project, a C-arm cone-beam CT will be used to provide guidance and "no-fly zones" to the robot that properly accounted for anatomical deformations imparted during the surgery. Hopefully, this integration will reduce registration error and improve the performan...
متن کاملVisualization System for Earth Environmental Data Base

Although this data is crucial to understanding such problems, there has become an over-abundance in variety of size, format, and filetype which makes it difficult for researchers to handle. We feel that earth enviro...
متن کاملExperience with a Graphical Data Base System
Over the past few years there has been an increase in the use of data base systems and computer graphics in scientific and engineering applications. While considerable work has been done on both graphics and data base support very little has been done on the interaction between the two. In this paper we discuss a graphical data base system that we have used in a number of applications. We descr...
