A scanned beam imaging system including a radiation source configured to provide a beam of radiation, a movable element configured to direct the beam of radiation onto a scanned area, and a collector configured to receive radiation returned from the scanned area. The imaging system further includes a housing that houses the movable element therein and a reference mark coupled to or received in the housing. The reference mark is positioned such that at least part of the radiation from the radiation source is directable at the reference mark.

A medical device includes a radiation source assembly having at least two radiation sources, where one or more of the radiation sources is adapted to generate an imaging beam for use in visualization of a scene and one or more of the radiation sources is adapted to generate a therapeutic beam for treatment of a medical condition. An optical fiber for directing radiation energy from the radiation source assembly toward a distal end of the medical device in the form of a beam. A reflector that receives the beam from the optical fiber, the reflector configured to direct the beam onto a field-of-view. A receiving system including a detector arranged and configured to receive radiation from the field-of-view to generate a viewable image. The imaging beam and the therapeutic beam are directed to follow a common path from the at least two radiation sources to the reflector.

Optical isolation means electrically isolates the electrical network ground of a logical contention bus from a transmitter coupled to the bus and having a local logic ground and a receiver coupled to the bus and having a remote logic ground. Optical isolation means may comprise a light source, such as a light emitting diode, and a light sensitive receiver optically coupled to and electrically isolated from the light source.
摘要:
A method for repairing or modifying an area of a patient's anatomy that comprises directing at least a portion of a scanning beam assembly to an area of a patient's anatomy, applying a radiation-responsive agent to portion of the anatomy, and exposing the radiation-responsive agent to radiation directed onto the agent by the reflector to cause the agent to therapeutically interact with the site. The scanning beam assembly including a radiation source capable of emitting radiation, a reflector that receives the radiation from the radiation source to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy, a detector to detect radiation returned from the anatomy, and a controller to convert the detected radiation into a displayable anatomy image.
摘要:
An apparatus and method for allowing multiple high and low resolution SBI and conventional FPA imaging devices to use a common high resolution monitor and archive device without increasing or significantly changing the footprint of existing devices. This system and method uses a frame grabber for digitizing video from the legacy FPA devices, a frame mapper for rendering or mapping the FPA video into the SBI digital format, a converter for rasterizing SBI data streams into pixel-oriented FPA video frames, an input selector for selecting which FPA or SBI imaging device to display on a high resolution monitor, an processor for storing and manipulating frames of video, a video output encoder for converting the SBI frames into a video signal appropriate for display on the high resolution monitor, and an output means for connecting to a storage device for archiving video and images.

摘要:
A method of controlling a medical device is provided. The method includes generating a beam of radiation using a radiation source assembly. The beam of radiation is directed toward a distal end of the medical device using an optical fiber. The beam of radiation is directed onto an area of interest by scanning the reflector in a scanning pattern, the reflector receiving the beam of radiation from the optical fiber. Radiation is collected from the area of interest using a collector to generate a signal for use in producing a viewable image. A loss of scan condition of the reflector is detected automatically by a control system.
摘要:
A scanning beam assembly for use in medical applications comprising a plurality of radiation emitters that emit radiation over different wavelength ranges, wherein at least one of the emitters emits radiation that is minimally absorbed by blood; a scanner including a reflector that receives radiation from the emitters and directs it onto a field-of-view; and at least one detector configured to receive the radiation scattered, reflected or transmitted by the field-of-view and generate an electrical signal.
