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 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 light transmitting section aligned on a longitudinal axis of the imaging system wherein the light transmitting section forms a part of the tunnel. The lighting arrangement also includes a reflector section that is radially outside the light transmitting section. In addition, the lighting arrangement includes at least one lighting device located between the reflector section and light transmitting section wherein the lighting device emits light that is reflected by the reflector section onto the light transmitting section and wherein the light is then transmitted through the light transmitting section and into the tunnel to circumferentially illuminate the tunnel.

Various parallax-free indicator devices, systems, and methods are disclosed. The indicator device may have a housing defining an aperture and a light source assembly at least partially disposed in the housing. The housing may be selectively securable via a fastener to an instrument in a selected orientation relative to the instrument. The light source assembly may have a light source operably coupled to a power source via a power circuit. The light source may be positioned within the housing to emit through the housing aperture. Upon activation, the light source assembly emits a parallax-free alignment indicator along an alignment axis that may have at least one of a selected angle and a selected displacement relative to a selected reference axis. The alignment indicator may guide a surgical procedure.

Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.

Assisting robotic arm setup in a surgical robotic system using augmented reality can include capturing a live video of a user setting up a robotic arm in a surgical robotic system. A visual guide representing a target pose of the robotic arm can be rendered onto the live video, resulting in an augmented live video for guiding the arm setup. The augmented live video can be displayed to the user while the user is following the visual guide to set up the robotic arm. The captured live video can be continuously processed to determine whether the robotic arm has reached the target pose.

An optical imaging system for imaging a target during a medical procedure is disclosed. The optical imaging system includes: a first camera for capturing a first image of the target; a second wide-field camera for capturing a second image of the target; at least one path folding mirror disposed in an optical path between the target and a lens of the second camera; and a processing unit for receiving the first image and the second image, the processor being configured to: apply an image transform to one of the first image and the second wide-field image; and combine the transformed image with the other one of the images to produce a stereoscopic image of the target.
