A spinal disorder diagnosis and treatment planning system is provided. The diagnosis and treatment planning system includes a mixed reality holographic display including at least one processor, at least one camera, at least one sensor, and being configured to acquire data points corresponding to a surface of a body adjacent to vertebral tissue. A computer database is configured to transmit imaging of the body including the vertebral tissue to the mixed reality holographic display. The mixed reality holographic display is configured to display a first holographic image of the vertebral tissue superimposed with a body image including the surface. Methods are also disclosed.

An eye imaging system can include a head-wearable fundus camera positioning helmet with an outer shell and a conformable liner that can include head location fiducials defining a specified plane. An attached articulating fundus camera fixture can include a fundus camera positioning indication system to indicate a position of the fundus camera with respect to an eye of the patient for acquiring one or more fundus camera images at the indicated position such that fundus camera images recorded over a chronic period of time are assessable using the position information from the fundus camera positioning indication system. The articulating fundus camera fixture can include an articulating arm and a fundus camera mount. The system can assist the patient with helmet positioning, and can automatically position the fundus camera for accurate image capture and analysis, such as using a trained machine learning model for patient evaluation, monitoring, or diagnosis.

A computer assisted surgery system comprising: a computerised surgical apparatus; and a control apparatus; wherein the control apparatus comprises circuitry configured to: receive information indicating a first region of a surgical scene from which information is obtained by the computerised surgical apparatus to make a decision; receive information indicating a second region of the surgical scene from which information is obtained by a medical professional to make a decision; determine if there is a discrepancy between the first and second regions of the surgical scene; and if there is a discrepancy between the first and second regions of the surgical scene: perform a predetermined process based on the discrepancy.

A head stabilization device or HFD includes a plurality of integrated markers. The HFD may be in the form of a skull clamp, vacuum bag, combinations thereof, or other supporting structure. The integrated markers include MRI markers detectable by an MRI scanner and fiducial markers detectable by a registration tool of a navigation system. The markers provide a reference point relative to an operation site in a patient for use in a navigation guided procedure and aid in registering or calibrating the location of the patient with captured images used in the navigation guided procedure.

An example physical tracking tool includes a main body defining a channel configured to receive a tool, the channel having a longitudinal axis; and one or more physical tracking features attached to the main body, each physical tracking feature comprising a plurality of planar faces, each planar face of the plurality of planar faces including different a graphical pattern of a plurality of graphical patterns.

A computer-implemented method for displaying augmented reality (AR) content within an AR device coupled to one or more loupe lenses comprising: obtaining calibration parameters defining a magnified display portion within a display of the AR device, wherein the magnified display portion corresponds to boundaries encompassing the one or more loupe lenses; receiving the AR content for display within the AR device; and rendering the AR content within the display, wherein the rendering the AR content comprises: identifying a magnified portion of the AR content to be displayed within the magnified display portion, and rendering the magnified portion of the AR content within the magnified display portion.

The invention relates to a method and a system for determining a pose of at least one object in an operating theatre, in a reference coordinate system of a pose detection device of a surgical microscope, involving the determination of the pose of the object by way of a movably arranged microscope-external pose detection device in a first coordinate system, the first coordinate system being a coordinate system that is arranged to be stationary relative to the operating theatre, the determination of the pose of the reference coordinate system by the non-stationary microscope-external pose detection device in the first coordinate system, and the transformation of the pose of the object from the first coordinate system into the reference coordinate system of the pose detection device of the surgical microscope.

Systems, methods, and instrumentalities are disclosed for switching a control scheme to control a set of system modules and/or modular devices of a surgical hub. A surgical hub may determine a first control scheme that is configured to control a set of system modules and/or modular devices. The surgical hub may receive an input from one of the set of modules or a device located in an OR. The surgical hub may make a determination that at least one of a safety status level or an overload status level of the surgical hub is higher than its threshold value. Based on at least the received input and the determination, the surgical hub may determine a second control scheme to be used to control the set of system modules. The surgical hub may send a control program indicating the second control scheme to one or more system modules and/or modular devices.

System for integrally measuring clinical parameters of the visual function including a display unit (20) for representing a scene with a 3D object having variable characteristics such as virtual position and virtual volume of the 3D object within the scene; movement sensors (60) for detecting the user head position and distance from the display unit (20); tracking sensors (10) for detecting the user pupils position and pupillary distance; an interface (30) for the user interaction on the scene; processing means (42,44) for analysing the user response based on the data coming from sensors (60,10) and the interface (30), with the characteristics variations of the 3D object; and based on the estimation of a plurality of clinical parameters of the visual function related to binocularity, accommodation, ocular motility and visual perception.

A histotripsy device may include a headset configured to be mounted to an about a cranium of a human or animal, at least one transducer mounted to the headset and positioned such that, with the headset mounted to and about the cranium, the at least one transducer is positioned over and in contact with at least one temporal or suboccipital region of the cranium, wherein the at least one transducer is configured to emit focused radiation in at an ultrasonic frequency or frequency range, at least one processor, and at least one memory having instructions stored therein executable by the at least one processor to cause the at least one processor to activate the at least one transducer to produce at least one pulse of ultrasonic radiation having a pulse duration of 1 milliseconds or longer.
