摘要： Method and device for digital x-ray tomosynthesis. Tomographic and/or three-dimensional images of an object are obtained with an x-ray source and a digital x-ray image sensor. The source, object and sensor are positioned relative to each other and attenuation data is obtained for a large number of rays of x-radiation through the object. A special algorithm is provided to convert the data into images. To calculate the images the algorithm uses iterative processes with a least squares type technique but with generalized (as opposed to specific) functions. The algorithm solves for the functions which are the images. Preferred embodiments include a system having an x-ray point source with a cone of diverging x-rays, a two-dimensional digital x-ray image sensor, two linear translation stages to independently move both the x-ray source and the digital x-ray image sensor, two rotation mechanisms to rotate the two linear translation stages, a microprocessor to control the data acquisition, and a computer programmed with a special algorithm to calculate the tomographic images. A plurality of sets of digital data (representing x-ray algorithm images of an object) are acquired by the digital x-ray image sensor, with the x-ray source and the digital x-ray image sensor located at different positions and angles relative to the object. The digital data representing the x-ray attenuation images is stored in the computer. Special mathematical algorithms then compute multiple images of the object using the acquired digital data. These images could include multiple tomographic images, a three-dimensional image, or a multiple three-dimensional images.

摘要： An imaging device for producing images from electron-hole producing radiation. Electron-hole pairs are produced in a radiation absorbing layer comprised of a photoconductive material. This layer covers an array of metal oxide semiconductor pixel circuits which are incorporated into and on a crystalline semiconductor substrate. Each pixel circuit has a charge collecting pixel electrode, a capacitor connected to the electrode to store the charges and a charge measuring transistor circuit. A voltage source provides an electric field across the radiation absorbing layer between the pixel electrodes and a radiation transparent surface electrode covering the radiation absorbing layer. A data acquisition system acquires and stores data derived from charge measurements and in a preferred embodiment a computer computes images from the data. The image may be displayed on a monitor or printed out on a printer. Preferred embodiments provide images from x-ray, ultraviolet and visible light.

摘要： The invention provides a digital x-ray mammography device capable of imaging a full breast. A movable aperture coupled with a movable x-ray image detector permits x-ray image data to be obtained with respect to partially overlapping x-ray beam paths from an x-ray source passing through a human breast. A digital computer programmed with a stitching algorithm produces a composite image of the breast from the image data obtained with respect to each path. In a preferred embodiment, a Schmidt camera images visible light produced at an x-ray to visible light conversion surface onto a digital detector array to produce an overlapping image pane with respect to each overlapping beam path.

摘要： This invention provides an imaging system for producing images from electromagnetic radiation such as x-rays. The system includes a detector comprised of a radiation-absorbing layer sandwiched between an array of CMOS integrated circuits (which we call pixel circuits) and a surface electrode layer transparent to the radiation. Each of the pixel circuits in the array has a charge collecting electrode. An external voltage applied between the surface electrode layer and the charge collecting electrodes produces an electric field across the thickness of the absorbing layer. Radiation passing through the transparent surface electrode layer is absorbed in the absorbing layer creating electron/hole pairs in the absorbing layer. A portion of the liberated holes (or electrons) migrates under the influence of the electric field toward the charge collecting electrodes, which collect the holes and store them as charges on small capacitors located within each circuit. This process results in a discrete distribution of stored voltages across the array proportional to the distribution of radiation photons incident on the absorbing layer. Circuitry in each pixel provides for the voltage on each pixel capacitor to be recorded via readout circuitry and permits the resetting of the pixel capacitors. Preferred embodiments provide fine resolution with a large number of pixels with dimensions about the size of the thickness of human hair.

摘要： A high resolution 3-D holographic camera. A reference spot on a target is illuminated by three spatially separated beamlets (simultaneously produced from a single laser beam), producing a lateral shear of a wavefront on the target. The camera measures the resulting reflected speckle intensity pattern which are related the gradient of the interfered complex fields. At the same time a flood beam illuminates the entire target and reflected speckle is also recorded by the same camera to provide the necessary object spatial frequencies. The illumination patterns are sequenced in time, stepping through offset phase shifts to provide data necessary to reconstruct an image of the target from the recorded reflected light. The reference spot phase and amplitude are then reconstructed, and the reference spot's complex field is then digitally interfered with the flood illuminated speckle field by use of a special algorithm. In order to obtain a high resolution 3D image of the target, a second measurement is acquired with the laser beam slightly shifted in frequency to second color.

摘要： A pair of adjustable focus eyeglasses having two lens units with at least one of the lens units having at least two lens elements. A mechanism is provided to pivot, about a pivot location outside each of the two lens elements, the position of at least one of the two lens elements relative to the other lens element in an angular direction generally perpendicular to a viewing direction. Specially designed surfaces are chosen such that small angular adjustments of the relative positions of the two lenses around a common pivot position in angular directions perpendicular or approximately perpendicular to a viewing direction results in changes in the combined focus of the two lenses of the lens unit. Preferred embodiments include two lens units with the lens system defining pairs of adjustable focus eyeglasses.

At least one of F1(u,v), F2(v), F3(v), F4(v) is non-zero.
