Abstract—This paper proposes a diagnostic support method that simultaneously detects and tracks abdominal tumors from moving camera images taken by ultrasonography. Ultrasound diagnosis requires a doctor’s experience because it is necessary to operate the equipment and perform the diagnosis simultaneously. Also, since the purpose of ultrasonic diagnosis is to find the presence of tumors, it is necessary to avoid overlooking them. We aim to develop a diagnostic support system that detects tumor cross-sections in each input frame using YOLOv3 and then tracks them using DeepSORT considering the instances of detected tumors. Here, even if a tumor disappears in an input frame due to doctor’s probe manipulation, it can be identified as the same instance between the input frames and finally be grouped into the same cluster. If diagnostic support information can be ensembled for each cluster, it is expected that the accuracy of tumor detection should be improved. Experimental results showed that our system could perform the clustering of tumor cross-sections in real-time.
