Abstract:
A system and process is provided for dynamically positioning or repositioning a robot in a surgical context based on workspace and task requirements, manipulator requirements, or user preferences to execute a surgical plan. The system and method accurately determines and indicates an optimal position for a robot with respect to a patient's anatomy before or during a surgical procedure. Optimal positions for a robot are intuitively indicated to a user, surgical procedures can illustratively include surgery to the knee joint, hip joint, spine, shoulder joint, elbow joint, ankle joint, jaw, a tumor site, joints of the hand or foot, and other appropriate surgical sites.
Abstract:
In a method and an apparatus to provide updated images during a roboticaliy- implemented surgical procedure, 3D data are obtained of a volume of a patient, which includes anatomy involved in the procedure. The anatomy is segmented from a reconstructed image of the volume. During the procedure, the surgeon applies forces on the anatomy, causing a geometric change of the anatomy. Force sensors in the surgical robot detect these forces, which are supplied to a processor that controls display of the segmented anatomy at a display screen. From the applied forces and the physical properties of the anatomy, the processor calculates the geometric change of the anatomy that has occurred and modifies the appearance and/or position of the displayed segmented anatomy on the display screen in real time during the procedure, so as to visualize the geometric change.
Abstract:
A tool for assisting in the planning or performing of electrical neuromodulation of a patient's spinal cord. The tool may have various functions and capabilities, including calculating a volume of activation, registering an electrode(s) shown in a radiologic image, constructing functional images of the patient's spinal anatomy, targeting of neuromodulation, finding a functional midline between multiple electrodes, determining the three-dimensional position of multiple electrodes, and/or accommodating for electrode migration. In certain embodiments, the tool can be embodied as computer software or a computer system.
Abstract:
An image-guided system (11) employing an imaging device (20), an instrument tracking device (80), a physician - centric display module (70) and a registration device. Imaging device generates imaging data (21) indicative of an image (23) of an anatomical region (24) of a patient within an imaging coordinate system (22). Instrument tracking device generates tracking data (31) indicative of a location of an instrument (33) within a tracking coordinate system (32). Physician - centric display module generates physician- centric data (71) indicative of a physician centric viewpoint (73) within a physician coordinate system (72). Registration device generates a physician - centric display (81) illustrating a physician - centric viewpoint of a graphic icon (34) of the instrument relative to the image of the anatomical region as a function of a transformation application of the physician - centric data to a registration of the imaging data and the tracking data. An illustration of the physician - centric viewpoint of the graphic icon of the instrument relative to the image of the anatomical region includes the graphic icon replicating motion of the instrument within the tracking coordinate system from a viewpoint of a physician.

Abstract:
The subject matter described herein includes methods, systems, and computer readable media for image guided ablation. One system for image guided ablation includes an ultrasound transducer for producing a real-time ultrasound image of a target volume and of surrounding tissue. The system further includes an ablation probe for ablating the target volume. The system further includes a display for displaying an image to guide positioning of the ablation probe during ablation of the target volume. The system further includes at least one tracker for tracking position and orientation of the ablation probe during the ablation of the target volume. The system further includes a rendering and display module for receiving a pre-ablation image of the target volume and for displaying a combined image on the display, where the combined image includes a motion tracked, rendered image of the ablation probe and an equally motion tracked real-time ultrasound image registered with the pre-ablation image.
