“…The geometric agreement reported in this article is consistent with prior work by Zhou et al, who developed a rigid registration method for a gynecological cylinder and Dise et al, who developed a region-growing algorithm for plastic interstitial needles (5,8). Zhou et al reported a disagreement of 0.75 AE 0.39 mm in a nine-patient study where the CT images had typical voxel dimensions of 1.17 Â 1.17 Â 2.0 mm 3 (8).…”

“…The results in our study are similar to those from other studies using CNNs with 3D U-net architecture for needle segmentation in prostate brachytherapy in ultrasound images. 18,26,33,34 Wang et al 33 used a large training set and reported an RMSD of 0.74 mm, which is slightly higher than the 0.55 mm found in the present study. Zhang et al 18,34 and Dise et al 26 both reported lower RMSD (0.29 and 0.40 mm) than achieved in this study, but neither were able to reach the 100% sensitivity which is the case for the present study.…”

“…In traditional approaches, like blood vessels and nerves, catheters are considered as tubular tree‐like structures 21,22 . These methods generally can be used in different imaging modalities including ultrasound (US), 19 CT, 20,23 and MRI 19 . Zhao et al 20 presented an automatic catheter tracking method in 3D US images by firstly applying a line filter method to enhance the contrast of the catheter against the background for regions‐of‐interest (ROI) selection using tubularness information, and then incorporating the Kalman filter into a catheter fitting model with the random sample consensus algorithm which was originally developed by Uherčík et al 19 to detect the catheters within ROIs.…”
