초록

The method and results of the software implementation of a echo processor for medical ultrasound imaging using a GPU (NVIDIA G80) is presented. The echo signal processing functions are modified in a SIMD manner suitable for the GPU's massively parallel processing architecture so that the GPU's 128 ALUs are utilized nearly 100%. The preliminary result for a frame of image composed of 128 scan lines, each having 10240 16-bit samples, shows that the echo processor can be inplemented at a high rate of 30 frames per second when implemented in C, which is close to the optimized assembly codes running on the TI's TMS320C6416 DSP.
