  • Patent number: 10807147
    Abstract: A platform for constraining a workpiece includes x-y stage connected to a base, wherein the x-y stage includes a floor and a y-axis datum and a x-axis datum aligned along a first axis and a second axis perpendicular to the first axis, respectively, and a primary constraint mechanism on the x-y stage. The primary constraint mechanism includes an x-axis wedge, a primary y-axis wedge and a primary z-axis clamp, and a primary linear actuator with a rod extendable and retractable parallel to the second axis. A primary linear actuator slides the x-axis wedge away from the x-axis datum, slides the primary y-axis wedge away from the y-axis datum, and rotates the primary z-axis clamp away from the workpiece. The primary z-axis clamp is attached to a cam with a pinion gear that engages a rack gear connected to the rod of the primary linear actuator.

  • Patent number: 10782429
    Abstract: A method and apparatus are provided for positron emission imaging to calibrate energy measurements of a pixilated gamma-ray detector using energy sharing events between channels of the detector. Due to conservation of energy, when the energy of a single gamma ray shared among multiple channels, the sum of measured energies across the respective channel must equal the original energy of the incident gamma ray. Further, the fractions of the original energy distributed to the respective channels can span the entire range of zero to the original energy. Thus, a single gamma-ray source (e.g., cesium isotope 137) can be used to continuously calibrate the nonlinear energy response of the detector over an entire range of interest.

    Abstract: A method includes forming a stacked structure of a plurality of first semiconductor layers and a plurality of second semiconductor layers alternately stacked in a first direction over a substrate, the first semiconductor layers being thicker than the second semiconductor layers. The method also includes patterning the stacked structure into a first fin structure and a second fin structure extending along a second direction substantially perpendicular to the first direction. The method further includes removing the first semiconductor layers of the first fin structure to form a plurality of nanowires. Each of the nanowires has a first height, there is a distance between two adjacent nanowires along the vertical direction, and the distance is greater than the first height. The method includes forming a first gate structure between the second semiconductor layers of the first fin structure.

  • Patent number: 10768318
    Abstract: A method and apparatus are provided for positron emission imaging to correct a recorded energy of a detected gamma ray, when the gamma ray is scattered during detection. When scattering occurs, the energy of a single gamma ray can be distributed across multiple detector elements—a multi-channel detection. Nonlinearities in the detection process and charge/light sharing among adjacent channels can result in the summed energies from the multiple crystals of a multi-channel detection deviating from the energy that would be measured in single-channel detection absent scattering. This deviation is corrected by applying one or more correction factors (e.g., multiplicative or additive) that shifts the summed energies of multi-channel detections to agree with a known predefined energy (e.g., 511 keV). The correction factors can be stored in a look-up-table that is segmented to accommodate variations in the multi-channel energy shift based on the level of energy sharing.

The apparatus can include processing circuitry configured to obtain calibration data representing a time and a position at which gamma rays are detected at a plurality of detector elements, and determine which gamma-ray detections of the calibration data correspond to multi-channel detections in which energy of a respective gamma ray is shared and detected by two or more of the plurality of detector elements. Additionally, the processing circuitry can be configured to determine a timing calibration of the plurality of detector elements by optimizing an objective representing agreement between time data of the multi-channel detections in the calibration data and the timing calibration.
