FootSeg: Automatic Anatomical Segmentation of Foot Bones from Weight-Bearing Cone Beam CT Scans

Weight-bearing cone beam CT (CBCT), which provides high-resolution scanning in the natural weight-bearing position, is an emerging technique in orthopedic research. The high quality scans from CBCT machines have greatly facilitated the treatment and diagnosis of human foot [1], such as foot align [2] and foot surgery [3] [4]. In these clinical practices, an essential step to analyze the CBCT foot scan is the anatomical segmentation of foot bones which provides an overall understanding of the patient's situation.
