Virtual 3D tumor marking-exact intraoperative coordinate mapping improve post-operative radiotherapy
The quality of the interdisciplinary interface in oncological treatment between surgery, pathology and radiotherapy is mainly dependent on reliable anatomical three-dimensional (3D) allocation of specimen and their context sensitive interpretation which defines further treatment protocols. Computer-assisted preoperative planning (CAPP) allows for outlining macroscopical tumor size and margins. ...
Computer-generated holograms (CGHs), such as those used in optical testing, are created by etching patterns into an optical substrate. Imperfections in the etching can cause small scale surface roughness that varies across the pattern. The variation in this roughness affects the phase and amplitude of the wavefronts in the various diffraction orders. A simplified model is developed and validate...
abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
Most computer-assisted surgery systems are an isolated standalone system in the operation room with obtrusive and cumbersome wired connections. Surgery data preparation, registration, segmentation, planning, etc. have to be running at one place. Dynamic data acquisition and cooperation during the surgical procedure is not currently possible. We develop the M-CASEngine system which provides a di...
