Abstract

We have developed a system to accelerate the snake algorithm using the Cell Broadband Engine (Cell processor). The snake method is a representative technique for the extraction of outlines such as the contours of organs in medical imaging diagnosis. However, it is difficult to set the optimal parameters for the snake method automatically, and it is therefore often necessary to perform parameter setting repeatedly in order to obtain the desired image. In our parallel computing system using Cell processors, we avoid this problem by assigning each processor a different parameter, allowing us to calculate multiple parameters at the same time for outline extraction by the snake method. The desired image is obtained in many of the simulations. The Cell processor is a representative multicore processor. Our system includes 16 PlayStation 3 consoles (home video game consoles manufactured by Sony), and each PlayStation 3 contains a Cell processor. Since we are able to employ the six calculation units in each Cell processor, our system with 16 PlayStation 3 consoles can perform 96 outline extraction calculations with different parameters at one time.
