Optimized GPU Framework for Pulsed Wave Doppler Ultrasound
Pulsed Wave (PW) spectrum Doppler ultrasound is avaluable tool for clinical diagnosis for flow velocity distributionin vessels. However, real-time processing of PW spectrum iscomputationally intensive, involving wall filtering, Fast FourierTransform (FFT), column filtering and linear averaging. In thispaper a very efficient implementation of a PW Doppler spectrumultrasound using the Compute Unified Device Architecture(CUDA?) platform developed by NVIDIA? Is presented. Byexploiting the explicit parallelism exposed in the graphicshardware we obtain more than one order speed-up gaincompared with that from standard CPUs. Finally, we get a rateof 7.60 μ s with one line of 256 samples, which is about 92 timesfaster than the CPU implementation.
