The present disclosure provides systems and methods for processing laser speckle signals. The method may comprise obtaining a laser speckle signal from a laser speckle pattern generated using at least one laser light source that is directed towards a tissue region of a subject and a reference signal corresponding to a movement of a biological material of or within the subject's body. The method may comprise computing one or more measurements using a first function corresponding to at least the laser speckle signal and a second function corresponding to the reference signal. The method may comprise generating an output signal in part based on the one or more measurements for the function space and using the output signal to aid a surgical procedure on or near the tissue region of the subject.

The portal component includes an axis, a first channel and second channel extending along the axis. The first sensor is secured within the first channel at a first angle with respect to the axis and directed inwardly toward a location. The first cable extends from the first sensor. The second sensor is secured within the second channel at a second angle with respect to the axis and directed inwardly toward the location. The first angle and second angle converge at the location to define a depth of perception. The second cable extends from the second sensor. The first display structure is disposed in proximity to a left aperture of an eyeframe, and the second display structure is disposed in proximity to a right aperture of the eyeframe.

Apparatus and methods are described for performing a procedure on a portion of a first side of a body of a patient using one or more tools. An imaging device images the portion of the first side of the patient's body. A display displays a mirror image of the portion of the first side of the patient's body to an operator. One or more control components are be operated by the operator. One or more robotic units hold the one or more tools, each of the one or more robotic units corresponding to a respective control component and mirroring a position of the corresponding control component. A computer processor processes inputs into the each of the control components such as to generate mirrored outputs at the corresponding robotic unit. Other applications are also described.

A lighting arrangement for a medical imaging system having a cylindrical wall that forms a tunnel that receives a patient to be scanned. The lighting arrangement includes a transparent wall section formed in the wall, wherein the transparent wall section extends along a transparent portion of a wall circumference. The imaging system also includes a lighting device located adjacent an outer surface of the transparent wall section. The lighting device extends along a device portion of a wall circumference corresponding to the transparent portion wherein light emitted by the lighting device is transmitted through the transparent wall section in a direction orthogonal to a longitudinal axis of the tunnel to circumferentially illuminate the tunnel. In addition, a system status is indicated by a color of light emitted by the LEDs. Further, light emitted by the lighting device varies in intensity to indicate a changing count rate.

A combined auto-fluorescence imaging and laser speckle contrast imaging (LSCI) system to enable intra-operative parathyroid identification and viability assessment with the same tool. The system includes a light source for emitting a beam of light to illuminate a target of interest, and an imaging head positioned over the target of interest for individually acquiring auto-fluorescence images and LSCI images of light from the illuminated target of interest responsive to the illumination. Auto-fluorescence imaging helps identify the parathyroid, while LSCI helps assess its viability.

Systems, devices, and methods for providing a surgeon with improved viewing angles during arthroscopic surgical procedures are provided. In some embodiments, a cannula is provided that includes an elongate body that can extend along a longitudinal axis, the body having a proximal end, a distal end, a lumen extending through the body between openings at the proximal and distal ends. The cannula can have a first flange member that can extend at least partially around at least one of the openings, and the first flange member can have a distal-facing surface, where at least a portion of the distal-facing surface can be reflective.

A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red).

A device, system and method for measuring free gas in a cavity of a subject. The device, system and method include a light source for emitting light with a wavelength associated with an absorption band of the free gas, an optical fibre connected to the light source and adapted to be inserted using an introducing member for internal illumination, and a detector adapted to be positioned on a skin surface for detecting light transmitted through the tissue. The device, system and method further includes a control unit for evaluating the detected transmitted light for determining the free gas, or a distribution of the free gas, or concentration of the free gas.
