When using HIFU to ablate a tumor with large volume,numerous sonications are necessary to cover the whole treatment area in the traditional scanning method with single focus,because the focal size of ultrasound is relatively small compared with that of tumor.In the consideration of safety and efficiency,the treatment parameters including foci arrangement,sonication sequence,duration of each sonication,the intersonication cooling time,need to be effectively determined,which leads to a complex problem of planning.The present paper proposed a multiple-mode strategy to ease the complexity for the HIFU treatment of large tumor,in which fast scanning method was used to generate the basic element of treatment.

针对现有生物芯片图像倾斜校正算法校正精度和运算速度的矛盾问题，提出对矩形样点和圆形样点图像分别采用改进的Hough变换和改进的Radon变换方法进行倾斜校正。改进的Hough变换首先对图像进行二值化，并仅统计矩形样点的上下边缘像素的Hough参数和累计值，然后根据所得的Hough参数空间提取占主导的直线组，最终计算出直线组的平均倾斜角度；改进的Radon变换在提取圆形样点边缘后，对边缘图像进行二级
