As one of the most important applications of digitalization, intelligence, and service, the
digital twin (DT) breaks through the constraints of time, space, cost, and security on physical …

Point cloud registration is the process of aligning and merging multiple point clouds into a
same coordinate system. It has many applications in computer vision, robotics, 3D …

Introduction Augmented reality (AR) is a novel visualization technique in which
pregenerated virtual 3D content is superimposed on surgical sites. This study aimed to …

Background Augmented reality (AR) navigation has been developed in recent years and
can overcome some limitations of existing technologies. This study aimed to investigate a …

Achieving and maintaining proper image registration accuracy is an open challenge of
image-guided surgery. This work explores and assesses the efficacy of a registration sanity …

Objective: The precise alignment of full and partial 3D point sets is a crucial technique in
computer-aided orthopedic surgery, but remains a significant challenge. This registration …

Background The existing face matching method requires a point cloud to be drawn on the
real face for registration, which results in low registration accuracy due to the irregular …

The traditional surgical navigation system for open liver tumor resection has some problems,
such as low tumor localization accuracy, high complexity of system operation, and heavy …

Objective: Biliary interventional procedures require physicians to track the interventional
instrument tip (Tip) precisely with X-ray image. However, Tip positioning relies heavily on the …

Background 2D CT image‐guided radiofrequency ablation (RFA) is an exciting minimally
invasive treatment that can destroy liver tumors without removing them. However, CT images …
