Automatic Hyoid Bone Tracking in Real-Time Ultrasound Swallowing Videos Using Deep Learning Based and Correlation Filter Based Trackers.
Sensors (Basel, Switzerland)
May 26, 2021
(1) Background: Ultrasound provides a radiation-free and portable method for assessing swallowing. Hyoid bone locations and displacements are often used as important indicators for the evaluation of swallowing disorders. However, this requires clinic...
Cryo-balloon catheter localization in X-Ray fluoroscopy using U-net.
International journal of computer assisted radiology and surgery
Apr 20, 2021
PURPOSE: Automatic identification of interventional devices in X-ray (XR) fluoroscopy offers the potential of improved navigation during transcatheter endovascular procedures. This paper presents a prototype implementation of fully automatic 3D recon...
Robot-assisted S2 screw fixation for posterior pelvic ring injury.
Injury
Nov 17, 2020
BACKGROUND: Percutaneous sacroiliac screw is one of the main methods to treat unstable posterior pelvic ring injury. However, complexity of pelvic anatomical structure increases the difficulty and risk with freehand operation. Besides, S2 screw fixat...
The impact of robot-assisted spine surgeries on clinical outcomes: A systemic review and meta-analysis.
The international journal of medical robotics + computer assisted surgery : MRCAS
Sep 28, 2020
BACKGROUND: Medical robotics has enabled a significant advancement in the field of modern spine surgery, especially in pedicle screw fixation. A plethora of studies focused on the accuracy of pedicle fixation in robotic-assisted (RA) technology. Howe...
A novel fluoroscopy-based robot system for pedicle screw fixation surgery.
The international journal of medical robotics + computer assisted surgery : MRCAS
Sep 25, 2020
BACKGROUND: Robot-assisted pedicle screw insertion has gained popularity in the spinal surgery field. Due to high cost, these spinal robots are not extensively applied in clinical surgeries. Developing an effective robot system with low cost and high...
Bone shadow segmentation from ultrasound data for orthopedic surgery using GAN.
International journal of computer assisted radiology and surgery
Jul 11, 2020
PURPOSE: Real-time, two (2D) and three-dimensional (3D) ultrasound (US) has been investigated as a potential alternative to fluoroscopy imaging in various surgical and non-surgical orthopedic procedures. However, low signal to noise ratio, imaging ar...
Toward automatic C-arm positioning for standard projections in orthopedic surgery.
International journal of computer assisted radiology and surgery
Jun 12, 2020
PURPOSE: Guidance and quality control in orthopedic surgery increasingly rely on intra-operative fluoroscopy using a mobile C-arm. The accurate acquisition of standardized and anatomy-specific projections is essential in this process. The correspondi...
Leveraging spatial uncertainty for online error compensation in EMT.
International journal of computer assisted radiology and surgery
May 22, 2020
PURPOSE: Electromagnetic tracking (EMT) can potentially complement fluoroscopic navigation, reducing radiation exposure in a hybrid setting. Due to the susceptibility to external distortions, systematic error in EMT needs to be compensated algorithmi...
A machine learning-based real-time tumor tracking system for fluoroscopic gating of lung radiotherapy.
Physics in medicine and biology
Apr 23, 2020
To improve respiratory-gated radiotherapy accuracy, we developed a machine learning approach for markerless tumor tracking and evaluated it using lung cancer patient data. Digitally reconstructed radiography (DRR) datasets were generated using planni...
Catheter segmentation in X-ray fluoroscopy using synthetic data and transfer learning with light U-nets.
Computer methods and programs in biomedicine
Feb 29, 2020
Background and objectivesAutomated segmentation and tracking of surgical instruments and catheters under X-ray fluoroscopy hold the potential for enhanced image guidance in catheter-based endovascular procedures. This article presents a novel method ...
