摘要
目的:利用计算机图像处理技术对模拟机扭曲变形的数字图像进行矫正处理研究。方法:利用标准网格模板获取矫正形变参数,然后使用形变参数对实际图像进行形变矫正处理。结果:处理的图像在边缘效果变化明显。整个图像得到较理想的矫正。结论:模拟机直接输出数字图像一定的形变扭曲。利用本方法可以对模拟机图像进行很好的形变矫正,以便保证放射治疗的质量。可以广泛推广使用。
Objective: To use the technology of image processing corrected the distorted digital images generatead by simulator. Methods Getting the distorted parameter from the image of standard grid plate in simulator, and we use these parameter to process the images of patient. Results The edge of images changed significantly. All corrected images had good result. Conclusion The ex- ported digital images from simulator had distorted. We got good correction result with using distorted correction method. In the end, this can improve quality assurance in radiotherapy. This method can be widely adopted.
