Standard-of-care clinical OCT systems require patients to sit upright, brace their head against the instrument, and fix their gaze into its sensing aperture. These limitations exclude those with involuntary head and eye movements, such as those present in Parkinson's disease and nystagmus, respectively, from undergoing OCT imaging. To overcome these restrictions, we combine our robotic OCT paradigm, which allows flexible patient positioning during imaging, with active cancellation of periodic motion to reduce image artifact during acquisition. We accomplish this by measuring eye motion with on-board pupil cameras, fitting the movement profile in real-time, and augmenting OCT scan waveforms using the predicted eye position. We evaluate this predictive imaging scheme with eye phantoms to precisely simulate motions typical of head and eye movement disorders and compare it to real-time scan aiming. Using registration shift in captured OCT images to quantify residual motion artifact, we demonstrate motion reduction by up to 98.5 % for typical nystagmus frequencies and an average 3.4 × reduction in residual motion compared to scan aiming alone. This approach may provide access to accurate OCT imaging for those with involuntary eye and head movement.","PeriodicalId":72029,"journal":{"name":"... International Symposium on Medical Robotics.

To avoid deviation from the intended trajectory, needle shape sensing and tip localization is crucial in providing the operator with feedback. There is an abundance of previous work that investigate the medical application of fiber Bragg grating (FBG) sensors, but most works select only one specific type of fiber among the many available sensor options to integrate into their hardware designs. In this work, we compare two different types of FBG sensors under identical conditions and application, namely, acting as the sensor for needle insertion shape reconstruction. We built a three-channel single core needle and a seven-channel multicore fiber (MCF) needle and discuss the pros and cons of both constructions for shape sensing experiments into constant curvature jigs. The overall needle tip error is 1.23 mm for the single core needle and 2.08 mm for the multicore needle.","PeriodicalId":72029,"journal":{"name":"... International Symposium on Medical Robotics.

A system to cooperatively control an integrated surgical robot for high dexterity manipulation within the eye's vitreous space was developed and validated in simulation. The system is composed of a 2 degrees of freedom (DoF) snake-like continuum manipulator that is attached to the end-effector of a 5-DoF rigid robot arm. It is capable of receiving position and orientation commands from a 5-DoF input device in real-time, as well as following pre-planned trajectories. The manipulator is moved to each target pose in real-time, using an optimization method to calculate the inverse kinematics solution. Constraints on the position and orientation ensure the target pose does not harm the patient within the vitreous space, enabling the robot to safely assist the clinician with vitreoretinal surgery when operating in real-time. The simulation demonstrates the system's feasibility and benefits over the existing non-dexterous system.","PeriodicalId":72029,"journal":{"name":"... International Symposium on Medical Robotics.

One example is the MRI-guided stereotactic robotic-assisted surgery for conformal brain tumor ablation, where the robot is used to position and orient a thin probe to target a desired region within the brain. Requirements such as the remote center of motion and precise manipulation, impose the use of complex kinematic structures, which result in non-trivial workspaces in these robots. The lack of workspace visualization poses a challenge in selecting valid entry and target points during the surgical planning and navigation stage. In this paper, we present a surgical planning toolkit called the \"NeuroPlan\" for our MRI-compatible stereotactic neurosurgery robot developed as a module for 3D Slicer software. This toolkit streamlines the current surgical workflow by rendering and overlaying the robot's reachable workspace on the MRI image. It also assists with identifying the optimal entry point by segmenting the cranial burr hole volume and locating its center. We demonstrate the accuracy of the workspace rendering and burr hole parameter detection through both phantom and MR-images acquired from previously conducted animal studies.","PeriodicalId":72029,"journal":{"name":"...

This paper presents the optimization and design of a four-bar linkage type tilt mechanism for a novel Steady-Hand Eye Robot (SHER) which can be used equivalently on both, the left and right patient side, during a bilateral approach with two robots. In this optimization, it is desirable to limit the workspace needed for compensation motions that ensure a virtual remote center of motion (V-RCM). The safety space around the patient, the space for the surgeon's hand and maintaining positional accuracy are also included in the optimization. The applicability of the resulting optimized mechanism was confirmed with a design prototype in a representative mock-up of the surgical setting allowing multiple directions of robot approach towards a medical phantom.","PeriodicalId":72029,"journal":{"name":"...
