Target registration and target positioning errors in computer‐assisted neurosurgery: proposal for a standardized reporting of error assessment

Abstract

Adoption of the proposed standardized reporting may help in the understanding and comparability of different accuracy reports.

Do Image Modality and Registration Method Influence the Accuracy of Craniofacial Navigation?

“…23 However, the target area in craniofacial surgery is substantially larger and an anthropomorphic phantom with target markers located in the entire craniofacial area may be required for an appropriate in vitro TRE assessment. 27 Further, it is unclear whether the different registration methods provide different TREs in the relative small FOV of CBCT compared with intraoperative and the standard diagnostic MSCT. In the present study, an anthropomorphic skull phantom was used to measure TREs based on bone markers, a registration template, and an external registration frame.…”

Accuracy and diagnostic yield of CT-guided stereotactic liver biopsy of primary and secondary liver tumors

“…The lateral error, i.e., the normal distance at the tip and skin entry point, and the angular error, i.e., the angle of deviation, between the planned and inserted needle were calculated as described by Widmann et al [12].…”

“…In the error calculations, the image fusion error and the influence of the draping with translucent plastic foil were included [12].…”

Targeting accuracy of CT-guided stereotaxy for radiofrequency ablation of liver tumours

“…Accuracy was evaluated by image fusion and thus the error of the image fusion is included in the error measurements (11). The accuracy of the image fusion has not been specified.…”
