【摘要】 论述了作者在心肌核素断层显像图像处理方面的研究工作,采用左心室长轴取向校正算法对明显存在主观性和变异性的左心室长轴人工选择进行校正。在算法上提出应用左心室心肌最大放射性计数值采样及Gauss Newton最优化方法进行模型参数的拟合。更多还原

【Abstract】 The study on myocardial radionuclide tomographic image processing is described in this paper. A new method was developed to reorient LV long axis in order to improve the accuracy and reproducibility of LV reorientation. We adopted the maximum counts of the myocardium to fit LV to LV long axis model under the Gauss-Newton optimization method.更多还原
