摘要： A MEMS apparatus for scanning an optical beam comprises a mirror operative to perform a rotational motion to a maximum rotation angle around a mirror rotation axis, and a bouncing mechanism operative to provide a bouncing event and to reverse the rotational motion. The bouncing event provides the mirror with a piecewise linear response to actuation by intrinsically nonlinear electrostatic forces. The bouncing mechanism includes an element chosen to impart an overall nonlinear stiffness to the system and is selected from the group of elements consisting of a bouncer and a pre-curved nonlinear stiffness element.

摘要： An image-reconstructive technique for examining a body by means of penetrating radiation, such as X-rays, is described in which a pre-body collimator having a two-dimensional array of radiation-transmitting holes each bordered by radiation non-transmitting walls is disposed between the body and the source of radiation, and a plurality of exposures are made onto a radiation-sensitive surface, in which the radiation is projected through the collimator while the radiation source is at a plurality of different locations, such that during the successive exposures, the radiation from the source passes through different ray paths defined by the holes in the pre-body collimator. The radiation level received by each of the radiation-sensitive surface elements is detected, stored, and processed to reconstruct the two-dimensional radiation pattern but with enhanced resolution. Preferably a post-body collimator is also used to suppress scattering. Described are a four-exposure procedure and a nine-exposure procedure.

摘要： The present invention is an electronic imaging device and method of expanding its dynamic range. The invention comprises modifying the imaging device by providing a comparator and reset trigger circuit located at or near the site of each of the pixels. The comparator triggers a reset mechanism when the voltage in the charged pixel reaches a reference voltage. During the global exposure time each individual pixel can be self-reset several times, depending on the intensity of the radiation incident upon it. At the end of the global exposure time, each pixel contains only the “residual value” of voltage that remains from the last individual self-reset to the end of the global integration time. An algorithm is implemented, which estimates and determines the number of resets undergone by each pixel during the global exposure time. From this number of resets the algorithm is able to reconstruct the true image. As opposed to prior art methods that make use of pixel reset the device of the invention does not contain electronic components for counting and remembering the number of times that each of the pixels was reset.

摘要： A calculi locator is provided having at least one ultrasound transducers in combination with a shock wave generator. The ultrasound transducer is rotatable about the longitudinal axis of a reflector of the shock wave generator. The shock wave generator includes a target focal point. The transducer is used to assure positional coincidence of the true location of the calculi and of the target focal point. Alternatively, either a mathematical correction unit is used or iterative measurements are used to correct for refraction errors in the location of the imaged calculi.

摘要： The system and method of the present invention minimizes artifacts caused by noncoplanarity between source and detector component in a computerized tomography system. The source component produces a beam of penetrating radiation which is rotatable about an axis and is incident on the detector component; and non-coplanarity is defined by the collection of the positions of the source component which defines a first plane, and by the collection of positions of the detector component which defines a second plane axially spaced from the first plane. Data obtained during a scan of a body located between the source and detector components are processed to form two images, one image being based on data related to one side of a focal plane interposed between the first and second planes, and another image being based on data related to the other side of the focal plane.

摘要： An improved three dimensional display device, for a single viewer. To the apparatus of U.S. Pat. No. 5,132,839 is added a mechanism for tracking the eye motion of the viewer. Because the control system "knows" the angles at which the device must project the frame images, only two (stereoscopic) frame images need to be projected in each frame, and a more complete illusion of three dimensionality, with respect to both lateral and vertical movement of the viewer, is provided.

摘要： A digital radiographic method and apparatus are described for the visualization of a portion of the circulatory system of a subject by feeding a catheter through a blood vessel while its progress is observed by exposing the respective portion of the subject's body to penetrating radiation, e.g., X-rays. In the described method and apparatus, all the prior positions of the catheter are stored so that all such prior positions visited by the catheter are displayed with each display of its current position. In addition, during the feeding of the catheter through the blood vessel, a substance relatively opaque to the radiation is injected into the blood vessel, whereby the digitized images of the previous catheter visits which are stored and displayed also include the image of the blood vessel and its junctures as revealed by the injected substance.
