This work presents a novel noninvasive tomographic method for assessing tumor progression through dynamic changes in T-cell distribution within the surrounding microenvironment. It is grounded in a game-theoretic perspective of the continuous competition between malignant expansion and immune access within the tumor microenvironment. This research has led to the following patent disclosure: https://scholars.cityu.edu.hk/en/publications/noninvasive-tomography-of-tumor-progression-via-changes-in-tcell-/.
