Tumor tracking in PET/CT is essential for monitoring cancer progression and guiding treatment strategies. Traditionally, nuclear physicians manually track tumors, focusing on the five largest ones (PERCIST criteria), which is both time-consuming and imprecise. Automated tumor tracking will allow real-time and precise matching of the numerous metastatic lesions across scans, enhancing tumor change monitoring. However, research is constrained by the limited availability of labelled medical tracking datasets. The proposed tumor tracking method by image registration, though just as a baseline, performs well on the annotated dataset, composed of simple cases.
