Figure 4.

The timeline view listed authors by clustering through keywords. Each node represents one author. The position of the node here represents the time of an author’s first publication. There were 15 clusters of keywords. In each cluster, the size of each node shows the contribution of the author. It seems that the keywords “prostate” and “breast cancer MRI” occur most recently, which suggest the active participations of researchers in practicing radiomics for oncology related to them, and it also shows that researchers have been practicing radiomics research related to dental artifacts since it lasts the longest duration.
