Two-stage generative adversarial networks for metal artifact reduction and visualization in ablation therapy of liver tumors
The strong metal artifacts produced by the electrode needle cause poor image quality, thus preventing physicians from observing the surgical situation during the puncture process. To address this issue, we pro...

A convenient and stable vertebrae instance segmentation method for transforaminal endoscopic surgery planning
Transforaminal endoscopic surgery (TES) is effective for treatment of intervertebral disc-related diseases. To avoid injury to the critical structures, preoperative planning is required to find a safe working ...

Multiple objective planning for thermal ablation of liver tumors
Preoperative treatment planning is key to ensure successful thermal ablation of liver tumors. The planning aims to minimize the number of electrodes required for complete ablation and the damage to the surroun...

A “eye-in-body” integrated surgery robot system for stereotactic surgery
Current stereotactic surgical robots system relies on cumbersome operations such as calibration, tracking and registration to establish the accurate intraoperative coordinate transformation chain, which makes ...

Robust extraction for low-contrast liver tumors using modified adaptive likelihood estimation
Liver tumor extraction is essential for liver ablation surgery planning and treatment. For accurate and robust tumor segmentation, we propose a semiautomatic method using adaptive likelihood classification wit...

An X-ray-free method to accurately identify the elbow flexion–extension axis for the placement of a hinged external fixator
Identifying the elbow flexion–extension (F–E) movement axis is important for placing a hinged elbow external fixator. An X-ray fluoroscopy-based method is widely used in clinical practice, exposing the patient...

An automatic markerless registration method for neurosurgical robotics based on an optical camera
Current markerless registration methods for neurosurgical robotics use the facial surface to match the robot space with the image space, and acquisition of the facial surface usually requires manual interactio...

A surgical robot with augmented reality visualization for stereoelectroencephalography electrode implantation
Using existing stereoelectroencephalography (SEEG) electrode implantation surgical robot systems, it is difficult to intuitively validate registration accuracy and display the electrode entry points (EPs) and ...

Subject-specific real-time respiratory liver motion compensation method for ultrasound-MRI/CT fusion imaging
Ultrasound-MRI/CT fusion imaging is widely used in minimal invasive surgeries, such as liver biopsy and tumor ablation. However, respiration-induced quasi-periodic liver motion and deformation cause unacceptab...

Target visibility enhancement for C-arm cone beam CT-fluoroscopy-guided hepatic needle placement: implementation and accuracy evaluation
Fluoroscopy-guided hepatic intervention is limited by target visibility and respiratory movement. A feasible procedure for visibility enhancement of the key regions and targets in 2D fluoroscopic images is nee...

Cerebrovascular segmentation and planning of depth electrode insertion for epilepsy surgery
Depth electrodes are inserted in the brain to locate the epileptogenic zone without craniotomy, but there is risk of surgical hemorrhage. Preoperative planning is required to mitigate this risk. A preoperative...
