✦ Synopsis
We have developed a tool to automatically detect inner and outer skull boundaries of a fetal head in ultrasound images. These boundaries are used to measure biparietal diameter (BPD) and head circumference (HC ) . The algorithm is based on active contour models and takes 32 s on a Sun SparcStation 20171. A high-performance desktop multimedia system called MediaStation 5000 (MSSOOO) is used as a model for onr future ultrasound subsystem. On the MSSOOO, the optimized implementation of this algorithm takes 24g ms. The difference (between the computer-measured values on MS50@0 and the gold standard) for BPD and HC was 1.43% (a = 1.00%) and 1.96% (a = l.%%), respectively. According to our data analysis, no significant differences exist in the BPD and HC measurements made on the MS5@00 and those measurements made on the Sun SparcStation 20171. Reduction in the overall execution time from 32 s to 248 ms will help making this algorithm a practical ultrasound tool for sonographers. 0 1997 World Federation for Ultrasound in Medicine and Biology.
