A computing device: compares an anatomical magnetic resonance (MR) image of a patient region and reference anatomical data associated with the region to determine a first transform of a bore anatomical coordinate space of the anatomical MR image to a patient anatomical coordinate space associated with the patient; determines, from the first transform, a second transform of a bore DWMR coordinate space of a DWMR image to a patient DWMR coordinate space associated with the patient, the anatomical and the DWMR images being in respective bore coordinate spaces associated with a bore of an MR device which acquired the anatomical and the DWMR images; transforms, using the second transform, the DWMR image to the patient DWMR coordinate space; and controls a display screen to render the DWMR image, as transformed, according to visual attributes associated with the patient DWMR coordinate space.

Device, system and method for transforming a diffusion-weighted magnetic resonance image to a patient diffusion-weighted magnetic resonance coordinate space

A monitoring method and system for providing visual enhancements during a medical procedure is described. The method includes capturing current visual information of a site during the medical procedure in real time, storing at least a portion of the captured visual information as stored visual information, identifying a feature of interest in at least one of the current visual information and the stored visual information; generating feedback data associated with the feature of interest, and displaying a virtual representation of the feedback data overlaid on the current visual information.

System and method for intraoperative video processing

The navigation systems and methods facilitate aligning a tool in relation to a trajectory in real-time to receive input data from a pre-operative plan image, at least one multi-modal image, and at least one real-time multi-modal image; interactively track at least one neural fiber, whereby interactively tracked fiber data is obtainable; automatically generate output data by way of data transformation using the input data and the interactively tracked neural fiber data; and transmit the output data to at least one of: at least one display device for rendering at least one real-time interactive navigation display for facilitating neural navigation, and at least one drive device for positioning at least one tracking device in relation to the tool in real-time, whereby real-time alignment data is achievable, and whereby at least one neurological structure is preservable.

Trajectory alignment system and methods

The present disclosure provides methods to process and/or display data collected using 3D imaging probes. The methods include: a) methods for mapping a single 2D frame onto a 3D representation of a volume; b) methods for dynamically updating portions of a 3D representation of a volume with a high temporal resolution, while leaving the remainder of the volume for contextual reference; c) methods for registering volumetric datasets acquired with high temporal resolution with volumetric datasets acquired with relatively low temporal resolution in order to estimate relative displacement between the datasets; and d) methods for identifying structures within a volume and applying visual cues to the structures in subsequent volumes containing the structures.

Data display and processing algorithms for 3D imaging systems

Methods and image-guided surgical navigation systems for updating an existing landmark registration of one or more landmark features in a common coordinate space are provided. The image-guided surgical navigation system includes a processor, an imaging device coupled to the processor, and a memory coupled to the processor. The image-guided surgical navigation system may be configured to capture a planar image of a region of interest, where the planar view image includes illustration of the one or more landmark features; generate a depth map from the planar view image; based on the depth map, identify a current location of the one or more landmark features in the common coordinate space; and transform the existing landmark registration to the current location of the one or more landmark features in the common coordinate space.

Methods and systems for updating an existing landmark registration

A surgical navigation system and method for identifying positions on a patient, including a processor, and a tracking system for tracking a pointer tool. The processor is programmed to initialize a surface trace acquisition, continuously record the positions of the pointer tool during the surface, conduct trace acquisition, combine the positions recorded during the surface trace acquisition into a surface trace, receive a patient image of the patient, extract a surface from the patient image, compute a registration transform between the surface traces and the surface for patient registration, segment the patient image into a regions where each region contains an anatomical landmark, determine a spatial distribution of surface traces among the regions; determine whether the spatial distribution in relation to each region minimizes deviance below a threshold, and if the determination is exceeding the threshold, provide information relating to such region.

System and methods for updating patient registration during surface trace acquisition

A trajectory guidance alignment system configurable to receive input data from an image, interactively track at least one user position, interactively track a tool position, automatically generate output data by way of data transformation using at least one of the input data, the user position data, and the tool position data, and transmit the output data to the display of a navigation system for rendering a real-time interactive navigation view corresponding to a surgical view for facilitating navigation of a medical procedure.

Trajectory guidance alignment system and methods

The application as disclosed herein describes systems and methods for performing patient registration using a surgical navigation system. This application attempts to provide for improvements upon existing systems through the addition of refinement steps used to increase the accuracy of registration and streamline said process. In some cases the improvements generally involve the manipulation of spatial data in an iterative manner.

System and methods for improving patent registration

A method and computing device for displaying surgical path data are provided. The computing device includes an input device, a display, a memory and a processor. The memory stores (i) an image of a volume of patient tissue having an outer surface, and (ii) anatomical data defining anatomical features of the volume. The processor receives an identifier of a target location within the volume; generates a plurality of paths from the outer surface to the target location, each path having a start point located on the outer surface, and an end point at the target location; for each of the plurality of paths, determines a score based on a comparison between the path and the anatomical data; and controls the display to present the outer surface and, at the locations of the start points, indications of the respective scores of the paths corresponding to the start points.
