摘 要：In this report, we extend our previous work where we proposed 1D Analytic Minimization (1D AM) of a cost function to calculate robust elasticity images to 2D AM. We show that 2D AM is much faster than 1D AM, which is critically important in creating real- time elastography. In elasticity reconstruction using an inverse problem framework. We also propose a novel strain addition, 2D AM produces high quality strain images in 2D which can be used for calculation technique using Kalman filters, which generates smooth strain images without blurring the images and removing sharp boundaries. We show using simulation, phantom and clinical trials that the 2D AM generates high quality strain images in real-time. This work is in published in 2 IEEE TMI articles (23 pages total), and in 5 conference proceeding papers (each paper 8 to 9 pages, 42 pages total). The papers are well received, resulting in more than 55 citations to date according to Google Scholar.
