摘要： A device and method is provided for a trackable suction tool for surgical use. The suction tool provides multiple configurations for the tip and reference tree, while allowing tracking by a navigation system. The tip and reference tree are attached to the suction tool handle by a snap fit, a threaded ring with key and slot connections or semi-Allen key connections, providing specific rotational configurations of the tip, handle and reference tree with each other. The handle may include a rotatable outer sleeve with a tear-shaped orifice for suction regulation and an inner sleeve with a corresponding opening, allowing variable placement of the tear-shaped orifice relative to the longitudinal axis of the suction tool. The features of the device allow a suction tool with multiple configurations to be trackable with a navigation system.

摘要： A head coil assembly includes a housing with a lower portion, an upper portion, a left portion, and a right portion, wherein each portion includes two or more radio-frequency (RF) coils, wherein the portions are sized and shaped to adjustably conform to a curvature of the subject's head for magnetic resonance (MR) imaging of the subject's head placed inside the housing, wherein the portions are operable to transition from an open position where the portions are sufficiently apart from each other to a closed position where the portions are adjusted to tighten a wrap around the subject's head along the curvature, and wherein the two or more RF coils in each portion are disposed in such manner that when the portions are operated to transition from the open position to the closed position, the RF coils of each portion remain decoupled to each other even along edges of each portion.

摘要： A method and device for tracking objects by surgical navigation systems. The method includes: capturing an image of the tracked object; determining whether a unique identifiable feature associated with at least one totem pattern is discernible in the image; when the unique identifiable feature is discernible: determining a position or an orientation of the tracked object based on the at least one totem pattern; and registering the at least one totem pattern in the surgical coordinate space; and when the unique identifiable feature is indiscernible: determining a position of each totem pattern relative to other totem patterns such that a combination of totem patterns within the captured image is a marker group detectable as a composite totem pattern; determining a position or an orientation of the tracked object based on the composite totem pattern associated with the tracked object; and registering the composite totem pattern in the surgical coordinate space.

摘要： An electronic device is provided including a processor, a communications interface coupled to the processor, a memory coupled to the processor, and a module saved in the memory. The module configures the processor to receive a first communications packet from a remote device via the communications interface including information useful for estimating a clock offset of the remote device, and determine an upper bound of the clock offset of the remote device with respect to the electronic device based on the information.

摘要： An apparatus is provided that is visible by both a three dimensional (3D) scanner system of a medical navigation system and a camera of the medical navigation system. The apparatus involves a rigid member and a plurality of markers attached to the rigid member. Each of the plurality of markers includes a reflective surface portion visible by the camera and a distinct identifiable portion visible by the 3D scanner system. The apparatus further involves a connector mechanism to connect the apparatus to a reference location. The apparatus is in a field of view of the 3D scanner system and the camera within a timeframe of the 3D scan.

摘要： Systems and methods are provided in which local tissue diagnostic measurements are correlated with archival local tissue diagnostic data from prior tissue analyses to supplement diagnostic measurements with tissue analysis data from prior tissue analyses having similar local tissue diagnostic data. The tissue analysis data may include information such as pathology data, outcome data, and diagnosis data. The archived local tissue diagnostic data and the tissue analysis data may be stored in a database, and employed for a wide variety of methods, involving preoperative, intraoperative, and/or postoperative phases of a medical procedure. Methods and systems are also provided for displaying, on a medical image shown in a user interface, hyperlinked reference markers associated with tissue analyses, where the reference markers are shown at locations corresponding to local tissue analyses, and where associated diagnostic data and/or tissue analysis may be viewed by selecting a given reference marker.

摘要： Disclosed herein are physiological phantoms incorporating sensors and sensor materials integrated with a tissue phantom of an anatomical part. The sensors and sensor materials include small diameter optical fibers containing Bragg gratings, thermochromic materials, electrical strain gauges, flexible strain gauges, shape sensing cables, electrochromic materials and etc. The sensors and sensing materials may mimic tissue as part of the tissue phantom. They may mimic the directionality, density, elasticity of the anatomical tissues they may be mimicking. The sensors and sensing materials may be sensitive to strain, heat, electricity, shape, light, and etc. similar to what may occur during medical procedures using various medical devices and tools such as a scalpel, a needle, a deep brain stimulation probe, a port used in brain or spinal surgery and etc.
