结果：FLAIR序列检出病灶66枚，常规自旋回波序列检出病灶46枚，前者较后者敏感性高。
Results:FLAIR sequence detected 66 focus of disease, whereas conventional SE sequence detected 46 focus of disease. The former was more sensitive than the latter.
在高帧率超声成像算法中，对回波信号进行有限衍射波束加权处理占用了成像中大部分计算时间。
In the a high frame rate (HFR) ultrasonic imaging system, the weighting process by limited diffraction beams on echo signal takes the most of the calculation time for constructing an image.
