Forbidden Region Dynamic Active Constraints in Robot-Assisted Minimally Invasive Surgery
Zejian Cui, Ferdinando Rodriguez y Baena
In robot-assisted surgery, Forbidden Region Active Constraints (FRAC) represent a control strategy that helps maintain task safety by generating anisotropic haptic guidance to surg…
Modular Robotic Catheters for Endovascular Aneurysm Repair
Alex Ranne, Jinshi Zhao, Ali Anil Demircali +5
Fenestrated/Branched endovascular aneurysm repair (FEVAR/BEVAR) require surgeons to navigate catheters and guidewires into various branches of the abdominal aorta, before deploying…
On-the-fly hand-eye calibration for the da Vinci surgical robot
Zejian Cui, Ferdinando Rodriguez y Baena
In Robot-Assisted Minimally Invasive Surgery (RMIS), accurate tool localization is crucial to ensure patient safety and successful task execution. However, this remains challenging…
Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation
Alex Ranne, Heiko Maier, Jinshi Zhao +6
To navigate medical instruments safely and accurately inside a patient's vascular tree, combining X-ray fluoroscopy with intermittent contrast injections is the gold standard. Howe…
CathFlow: Self-Supervised Segmentation of Catheters in Interventional Ultrasound Using Optical Flow and Transformers
Alex Ranne, Liming Kuang, Yordanka Velikova +2
In minimally invasive endovascular procedures, contrast-enhanced angiography remains the most robust imaging technique. However, it is at the expense of the patient and clinician's…
AiAReSeg: Catheter Detection and Segmentation in Interventional Ultrasound using Transformers
Alex Ranne, Yordanka Velikova, Nassir Navab +1
To date, endovascular surgeries are performed using the golden standard of Fluoroscopy, which uses ionising radiation to visualise catheters and vasculature. Prolonged Fluoroscopic…
