Digital scan converter (DSC) is a key component in their image processing systems, which performs coordinate transformation and image interpolation between two adjacent scan lines. We present a new image processing system scheme based on the FPGA technology. In this scheme, we mainly focus on the DSC component. In the DSC system, we applied the CORDIC algorithm to perform the transformation between Cartesian coordinates and polar coordinates, and use a modified R-theta algorithm to perform the image interpolations. At the same time, we mapped the whole system into a Xilinx FPGA device (XCV50-BG256). Its performance in practical application indicates that the scheme is valid and can improve the image quality significantly and greatly reduce the dimensions of this instrument.","PeriodicalId":74567,"journal":{"name":"Proceedings.

As a typical example, separating Web servers and data servers by CORBA technique can expand basic Web-based telemedicine system into a distributed system. As database would be fragmented on distributed sites, query optimization should be employed when possible. In addition, by estimating the resource utilization ratio, it is easy to achieve maximal profits for the distributed telemedicine system.","PeriodicalId":74567,"journal":{"name":"Proceedings.

MEDSET allows ISs to develop in an evolutionary way, along different \"dimensions\": the number of supported business processes, the number of user functions, the number of users and the degree of formalization of data. The program component of MEDSET is based on Internet technology, so ISs built under MEDSET can be used in a remote mode as well as locally.

Initial visualization of the anatomic region of surgical interest (AROSI), followed by segmentation and extraction of selected structures in each slice produces 2D masks for each anatomic structure. These are stacked to create 3D virtual anatomic models, either surface or volumetric, which can be transformed into physical 3D models by finite element, or other physical modeling algorithms. The methods for building 3D models will be discussed. Examples are: 1. the Lawrence Berkeley National Labs frog 2. the Stanford Visible Female (pelvis) segmentation is the selection of desired structures, and /or suppression of undesired structures prior to rendering extraction of selected structures in each slice allows for visualization of several types: 3D volumetric visualization and analysis can be done from unreconstructed images, reformated planes, curved planar reformatting, surface and volume rendering, maximum intensity projection, and shaded surface displays. transforming 3D volumetric models into physical models by finite element, or other physical modeling algorithms provides opportunity for deformations, incisions, etc. an application of such models, instrumented with accelerometers and pressure sensors is the crash testing of Cyber Dummies","PeriodicalId":74567,"journal":{"name":"Proceedings.

The focus of these workshops is to facilitate the use and growth of software safety techniques. The software safety field is relatively new (roughly 15 years old in the U.S.); therefore, engineers and scientists are constantly working on new ideas and techniques for developing safety-critical software systems. Unfortunately, safety-critical techniques are not finding there way into industry as fast as some need or desire. This paper (and the software safety workshops) are one means for trying to achieve these goals.","PeriodicalId":74567,"journal":{"name":"Proceedings.
