摘要： Methods and systems that provide quantitative assessments of in vivo thermal treatments, such as ablations, during image-guided surgeries using a high-resolution pre-operative MRI image segmented with a shape constrained and deformable mesh representations of brain structures and generating 3-D visualizations of thermally treated volumes during the thermal treatment that can provide near real time visual and quantitative feedback to a clinician.

摘要： Systems and methods are provided that automatically determine whether a prospective surgical trajectory will collide with a patient's skull using a 3D representation of the patient's cranial region (including the patient's scalp, skull, and brain) adapted from imaging data of the patient's cranial region (e.g., MRI data or CT data). Taking a particular patient's varied skull thickness into account, examples can determine bone collision during a trajectory planning stage before or after a stereotactic frame is mounted to the patient. Accordingly, examples may preemptively alert a clinician to a potential bone collision before the prospective surgical trajectory is underway/has been executed, thereby reducing the risk of bone collision during the surgical procedure.

摘要： Devices for transferring fluid to or from a subject include a plunger assembly coupled to or coupleable to a cannula assembly to allow target fluid to be “front-loaded” into a distal end of the cannula assembly while the stylet is withdrawn a distance to create a vacuum and define a flow channel.

摘要： Methods and systems that identify an intrabody orientation of a directional medical device, such as a deep brain stimulation (DBS) lead, use a mesh model. The mesh model is a shape-constrained trained model of fused post-operative MRI and CT image data of brains from a set of patients defined by intensity of artifact patterns corresponding to a passive orientation marker on a physical device.

摘要： Surgical planning systems that automatically identify one or a plurality of different candidate trajectories to a defined intrabody treatment region. The systems can rank the identified candidate trajectories in an order of hierarchy based on defined parameters such as distance from a critical no-go location and whether a single or multiple different candidate trajectories are needed to provide coverage of the defined intrabody treatment region. The surgical planning systems are also configured to provide a User Interface that defines a workflow for an image-guided surgical procedure and allows a user to select one or more of the identified candidate trajectories steps in the workflow.

摘要： Examples of the presently disclosed technology provide systems and methods for improved image registration for image-guided brain interventions. The disclosed systems and methods use sparse surface-based correspondences between vertices of patient-specific 3D mesh representations to fit a non-rigid transformation function for estimating a deformation field that maps one cranial image (e.g., a source image used for surgical trajectory planning) to another cranial image (e.g., a reference image obtained during an image-guided brain intervention).

摘要： A cannula for transferring a substance to and/or from a patient includes a tubular support sleeve and a transfer tube. The support sleeve includes a rigid tubular member defining a lumen extending from a proximal end to a distal end of the tubular member. The transfer tube is positioned in the lumen and extends beyond each of the proximal end and the distal end of the tubular member. The tubular member includes a rigid, MRI-compatible material.

摘要： Devices for transferring fluid to or from a subject include an extension tube assembly with an axially extending inner tube configured to couple to an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen and an axially extending inner tube. The inner tube extending through the tubular cannula defines an exposed needle tip and is in fluid communication with the inner tube of the extension tube assembly. The needle tip extends out of a distal end of the tubular cannula a suitable distance.

摘要： Systems and methods for transferring fluid to or from a subject use a set of MRI compatible components that can aspirate intrabody structure and/or fluids. The components include a device guide, a semi-rigid guide sheath configured to slidably extend through the device guide, a stylet releasable coupled to the guide sheath and extending a fixed distance out of a distal end thereof, and a cannula coupled to flexible tubing that is releasably interchangeably held in the guide sheath in lieu of the stylet.
