CAD Overlay CAD Overlay CAD Overlay is a commercial software application for raster-to-vector translation in 2D computer-aided design (CAD) and drafting — available between 1988 and 1996 as a third-party application for AutoCAD and other CAD systems. Developed and marketed by Image Systems Technology, CAD Overlay was first released in January 1988 running on AutoCAD Version 2.6. CAD Overlay replaced the previous generation of automatic raster-to-vector translation systems by embedding scanned documents and images directly in the CAD system. CAD Overlay was derived from a custom AutoCAD application developed using the Nth Engine graphics board in 1987 by David Chassin for Image
Computer-assisted orthopedic surgery and radiation exposure while providing accurate guidance to the surgeon via ultrasound imaging. This navigation method is still currently being tested, and is not readily available for clinical use. Computer-assisted orthopedic surgery Computer-assisted orthopedic surgery or computer-assisted orthopaedic surgery (sometimes abbreviated as CAOS) is a discipline where computer technology is applied pre-, intra- and/or post-operatively to improve the outcome of orthopedic surgical procedures. Although records show that it has been implemented since the 1990s, CAOS is still an active research discipline which brings together orthopedic practitioners with traditionally technical disciplines, such as engineering, computer science and robotics. The principal idea
