Abstract:Almost all successful nodule detectors rely heavily on a fixed set of anchor boxes. In this paper, inspired by the success of the keypoint estimation method in natural image detection, we propose an anchor-free framework for accurate pulmonary nodule detection. We first present a novel representation for detecting nodules, in terms of their 3D center locations, which reduces the number of hyper-parameters and the corresponding computation related to anchors, thus making the nodule detection pipeline much simpl… Show more
“…It can also be observed from Table 4 that our proposed system achieves the CPM score of 88.2%, being at the middle among the other works. Our methods are only 2.4% less accurate than the top performer at 90.6% [45], while still have a considerable gap with the other end ( [23] and [46] at 79.0% and 79.6%, respectively).…”

“…Table 5 presents FROC performance and CPM score of our proposed system and compares the results with other methods on SPIE-AAPM dataset. From the table, it can be observed that even with unseen data from SPIE-AAPM dataset, our method achieves a sensitivity of 89.3% and a CPM score of 84.8% which outperforms other nodule detection methods [45], [50] on the same dataset. These results demonstrate the generalization of our proposed model.…”
