A method for X-ray imaging includes determining one or more pre-shot parameters corresponding to a region of interest in a subject based on an optical image of the region of interest obtained from an optical sensor. The method further includes controlling an X-ray device to generate a pre-shot X-ray image using a first X-ray dosage, based on the one or more-pre-shot parameters. The method also includes determining at least one main-shot parameter based on the pre-shot X-ray image. The method includes controlling the X-ray device to generate a main-shot X-ray image using a second X-ray dosage greater than the first X-ray dosage, based on the at least one main-shot parameter.

A radiography system for imaging an object, comprises a radiation source located in a first side of the object for generating a plurality of beams; a detector located in a second side of the object for detecting the plurality of beams from the radiation source. The radiography system comprises a first sensor located in the first side of the object for obtaining an object related information and a second sensor disposed on the detector for obtaining a detector-position related information. The radiography system further comprises a controller configured to reconstruct a 3D scene based on the object related information obtained by the first sensor and the detector-position related information obtained by the second sensor and control an operation of at least one of the radiation source and the detector based on the reconstructed 3D scene. A method of controlling the radiography system is also disclosed.

The present approach relates to the use of augmented or enhanced reality to facilitate positioning of one or more of a patient, X-ray source, or detector during an image acquisition. In certain implementations, sensors and/or cameras provide quantitative information about the position of system components and the patient, which may be used to generate a positioning image based upon reference to an anatomic atlas.

A system and method for generating a digital image in fluorescence gel imaging is disclosed. The method includes providing a gel sample and placing the gel sample on a flat panel detector having array of photodiodes and transistors that collect light generated from the gel sample. The gel sample is illuminated using a light source integrated into the flat panel imaging system and light emitted by the gel sample responsive to an excitation of the gel sample by light provided by the light source is then collected, with the light emitted by the gel sample being collected by the array of photodiodes of the flat panel detector and converted to electric charges to generate light data. The light data is then processed to generate a digital image of the gel sample.

Chiral organic polymers doped with or appended by nonlinear optical dyes are disclosed. The use of chiral polymers produces a more stable noncentrosymmetric environment for the dye molecules resulting in unexpectedly long relaxation times as compared with previously used organic polymers. In addition, the NLO/chiral polymer materials exhibit high electro-optical coefficients (r,), high nonlinear optical coefficients (d,), improved long-term thermal stability, and at the same time retain the processing advantages associated with organic polymers. Thus, the present NLO/chiral polymer materials are extremely well-suited for use in second-order nonlinear optical and optoelectronics devices.

Chiral polymer compositions exhibiting nonlinear optical properties

An optical coupling device, or a compound waveguide, in which optical energy is coupled to or from an optical signal propagating along a transmitting waveguide is disclosed. The optical coupling device includes a thin film organic crystal waveguide positioned in optical proximity to a portion of the transmitting waveguide. The organic crystal waveguide has a first, coupling surface facing the transmitting waveguide through which the optical energy is coupled. The transmitting waveguide may be a fiber optic having at least some material removed along a side thereof to facilitate the coupling of optical energy between the fiber optic and the organic crystal waveguide. Polishing and lapping methods for producing the thin film organic crystal waveguide, with optically smooth surfaces, are also disclosed, as are organic salt implementations of the organic crystal.
