Abstract :
We recently implement a real time software Digital Scan Converter algorithm for sector B-mode ultrasound based on a PC with 1.6G dual-core CPU and 1GB RAM. Several measures are taken to increase the speed, such as lookup table (LUT), integer arithmetic, section interpolation, double-buffer for incoming data and multi-threaded coding. The algorithm programmed with C++ runs on Linux operating system. Experimental results show that scanning conversion time of each frame is less than 15ms, which fully meets the requirement of real-time image display for B-mode ultrasound scanner.
