摘要： 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.

摘要： Disclosed herein is a method for multimodal imaging during a medical procedure using magnetic resonance imaging (MRI) and Raman optical imaging which involves administering an MRI imaging contrast agent that a chemical structure having charge-transfer electronic transitions. The tissue is imaged using and MRI device and the tissue is illuminated with excitation light that has spectral components that are approximately tuned close to one of the charge-transfer electronic transitions thereby producing enhanced Raman optical signals which are analyzed to produce Raman imaging data followed by registering the MRI and Raman imaging data. The present disclosure also provides a method for ionizing laser plumes through atmospheric pressure chemical ionization.

摘要： A system for adjusting an operating state of a medical electronic device is described. In an aspect, the system includes an optical tracking system configured to detect three or more tracking markers. The system also includes a processor coupled with the optical tracking system. The processor is programmed with instructions which, when executed, configure the processor to: configure an input command by assigning at least one operating state of the medical electronic device to a particular state of at least one of the tracking markers; after receiving a priming command, identify a present state of the tracking markers based on data from the optical tracking system; compare the present state with the particular state assigned to the operating state; and based on the comparison, determine that an input command has been received and adjust the operating state of the medical electronic device to the assigned operating state.

摘要： A system and method is provided for planning a surgical procedure. The system includes a model of an anatomical region including simulated bone, a tracked tool, a tracking system, a display device, and a computer system configured to receive information from the tracking system, generate and display the model and the tracked tool, and store the tracking system information in a computer readable memory that is portable to a surgical navigation system. The method includes acquiring volumetric data of a patient anatomical region, extracting, providing and registering a three-dimensional model with the volumetric data, using a tracked tool to perform a simulated surgical procedure including removing and replacing a bone section on the model, viewing the model and the tracked tool on a display device, recording the procedure with a tracking system, storing the procedure in a computer readable memory, and porting the procedure into a surgical navigation system.

摘要： A system and methods for labeling tractography, having a tract segmentation and a tract labeling atlas, in a presence of a lesion in a brain, involving: a graphical user interface (GUI) comprising a tool configured to facilitate adjusting a displacement for intraoperatively reperforming the tract segmentation in approximately real time, modeling deformation of the tract labeling atlas by facilitating modeling a force exerted by the lesion on the brain, and defining parameters of a size, a shape, and a level of the displacement condition; and a processor in communication with the GUI and configured to: determine whether an infiltration condition and a displacement condition appears in the tractography; if the infiltration condition and the displacement condition is determined to appear in the tractography, estimate the infiltration condition and the displacement condition; if the displacement condition is determined to appear in the tractography, instruct the GUI to render the tool and model the force exerted by the lesion on the brain by using the parameters, whereby a new tract segmentation and a new tract labeling atlas are provided; and if the displacement condition is determined to be absent from the tractography, refrain from modeling the force, a presence of only the infiltration condition being assumed.

摘要： Described here are systems and methods for imaging a subject with a magnetic resonance imaging (“MRI”) system using magnetic field gradients generated by one or more gradient coils operating with gradient coil settings (e.g., gradient amplitudes, gradient slew rates) above a threshold at which peripheral nerve stimulation (“PNS”) is likely to be induced in the subject. A dielectric assembly is positioned adjacent a skin surface of the subject such that the dielectric assembly attenuates the local electric fields induced by the magnetic field gradients, which would be likely to induce PNS when the dielectric assembly is not arranged adjacent the skin surface of the subject. As a result of the dielectric assembly placed adjacent the skin surface of the subject, the gradient coil settings can be increased above the threshold without inducing PNS in the subject.

摘要： Navigation and simulation systems and methods for minimally invasive therapy in which the navigation system imports a planning method using patient specific pre-operative images. The navigation system uses intraoperative imaging during the medical procedure to update the preoperative images and provides images of tracked surgical tools along the surgical path prepared from the preoperative images.
