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.

A first expression of a first apparatus includes a medical scanned beam imager including an optical dome and a scanner, wherein the optical dome has a variable optical power distribution. A first expression of a second apparatus includes a sleeve assembly which is attachable to a medical scanned beam imager and which includes an objective element which covers an optical dome of the imager when the sleeve assembly is attached to the imager. A second expression of a second apparatus includes a sleeve assembly and a medical scanned beam imager wherein the sleeve assembly is attached to the imager and an objective element of the sleeve assembly covers an optical dome of the imager. A first expression of a third apparatus includes an objective element and a medical scanned beam imager having an optical dome wherein the objective element covers the optical dome and is attached to the imager.
摘要:
An assembly comprising a radiation source to generate a beam of radiation, a modulator for modulating the power of the beam of radiation as a function of the position of the beam within a field-of-view to maintain the beam's power within a desired exposure level as the beam scans the field-of-view, and a reflector oscillating in a sinusoidal manner to direct the beam of radiation onto a field-of-view.
摘要:
A general absolute value circuit for developing a true, symmetric or bipolar, absolute value output signal from an input charge signal, compact enough to be used on a sensor chip incorporated into (or used in combination with) a pixel processor of the type used in imaging and other systems that collect electromagnetic radiation as part of on-chip circuitry, includes a balanced differential amplifier combined with a merged dual shelf transistor structure. The balanced differential amplifier, in response to an input charge signal, drives the merged dual shelf transistor structure which in turn generates the desired true absolute value output signal. Such circuitry may be used in imaging systems to implement focal-plane processing algorithms or may be used for performing a single read true absolute value computation by a pixel processor located on a sensor chip. The merged dual shelf transistor structure enhances performance and speed of the processor in which it is incorporated.
