3D vertebral modeling and robotic cutting tailor bone preparation to improve intervertebral disc prosthesis positioning and fit.

Off-resonance RF excitation uses catheter actuation coils for real-time MR localization without contrast agents or added fiducials.

When instruments approach the displayed edge, position tracking shifts the navigation view to preserve anatomy-relative visibility.

A digital screen serves as both an optical tracking marker and surgical information display, adapting graphics to dynamic conditions for accurate pose detection.

The case translates housing rotation into scaled shaft articulation, using palm and finger interfaces to ease precise surgical maneuvering.

Piezoelectric resonance sustains oscillations that help passive coil markers achieve accurate tracking with simpler readout electronics.

A multi-marker tracker registers patient anatomy and a robotic arm, preserving tracking accuracy without bed mounting.

Anisotropic magnetic-field sensing locates implanted non-radioactive seeds for precise tumor guidance without wires or radiation.

Tracking imaging-device movement and applying a display-to-window transform gives operators cues when commands, motion limits, or degrees of freedom diverge.

Variable endoscope illumination can distort NIR dye measurements; reference-normalized fluorescence improves diseased-margin visualization during surgery.

Optical-fiber sensors replace electromagnetic tracking to localize medical device tips without radiation or contrast media exposure.

Markerless optical registration projects 3D medical information onto the operative field, reducing attention shifts and supporting instrument tracking.

Long-range catheter transport pairs with magnetic actuation and multiple imaging modalities to place microrobots in tortuous, hard-to-see body regions.

Catheter electrode signals outside defined characteristics trigger display alerts, helping physicians review relevant events during cardiac mapping.

Rigid orthopedic endoscopes can leave blind spots; this case combines a bendable shaft, angle detection, and optical-electromagnetic navigation.

Obstructed cameras can pause surgical tracking; chained pose transforms maintain consistent XR navigation across multiple tracking sources.

Magnetic implants form digestive-tract anastomoses through natural orifices, offering a minimally invasive pathway for T2DM care.

Fusing surgical-image features with visual kinematics helps recognize stages despite complex instrument and organ interactions.

Tracking the first bone cut lets the robotic system update later cuts, limiting cumulative deviation and improving prosthetic alignment.

A shaft-surrounding sleeve connects the marker to a medical instrument, simplifying setup while preserving optical position and orientation tracking.

A pivoting guide and sliding anchor support secure tracker adjustment while reducing bulk and interference near the surgical site.

A radiotransparent substrate supports optical tracking and radiopaque fluoroscopic patterning to align patient markers with the spine.

A printed absorbent layer covers part of a reflective surface, simplifying low-cost disposable surgical tracking.

Electromagnetic sensors track a ureteroscope relative to the renal papilla to guide precise percutaneous access and reduce radiation exposure.

A processor builds a predefined-thickness 3D shell from organ measurements to reveal unmapped regions and assess mapping quality in real time.

Patient movement and field-generator deviations can disrupt tube tracking; electromagnetic mapping maintains real-time placement guidance.

Motion sensing and learned models predict the next surgical instrument while a robot arm delivers it, reducing nurse fatigue and improving accuracy.

Brain shift can make pre-planned images unreliable; intraoperative imaging automatically updates patient-to-image registration during surgery.

Stepwise guidance exposes how automated surgical plans are generated, helping users customize recommendations while storing edits to improve later plans.

Manual soft-tissue assessment can leave replacement joints imbalanced; robotic motion limits and perturbation data support more precise balancing.

Conductive hypertonic saline lowers tissue impedance so bronchoscopic RF energy can heat and ablate peripheral lung tumors.

Panoramic views synthesized from multiple endoscopic images help operators navigate branching anatomy despite sidewall obstruction and limited field of view.

Projected patterns and 3D cameras combine with inertial tool tracking to maintain real-time vertebra and instrument guidance despite movement and occlusion.

An adjustable holder follows finger posture while keeping body-to-operation-part motion within a permissible range to prevent unintended control.

The hybrid tracker compares magnetic sensor data with impedance patch locations to separate physical catheter movement from field distortion.
