    摘要: A system for three-dimensional tomosynthesis imaging of a target element includes an image acquisition element and a processor. The image acquisition element obtains a plurality of images of the target element from a plurality of angles and includes a radiation source that is positionable at a plurality of angles with respect to the target element and a radiation detector. The radiation detector is positioned so as to detect radiation emitted by the radiation source passing through the target element and determine a plurality of attenuation values for radiation passing through the target element to establish a radiation absorbance projection image of the target element for a particular radiation source angle. The processor is configured to apply an iterative reconstruction algorithm to the radiation absorbance projection images of the target element obtained from a plurality of radiation source angles to generate a three-dimensional reconstruction of the target element.

    摘要: A firearm cartridge system is provided and includes a case with a neck portion, body portion, shoulder portion, a base portion, and a indentation. The neck portion has a diameter between about 0.249 in to about 0.256 in. The body portion tapers from a first end having a diameter between about 0.465 in to about 0.475 to a second end having a diameter between about 0.449 in to about 0.458 in. The shoulder portion connects the body portion and neck portion and has a diameter between about 0.395 in to about 0.405 in. The base portion is positioned on the second end of the body portion and has diameter between about 0.463 in to about 0.477 in. The indentation joins the body portion and the base portion and includes a sidewall with angle between 30° to 42°.

    摘要: A measurement compensation mechanism for an electronic radiation source-based borehole logging tool that compensates for geometric variations in the direction output of an x-ray source is provided, the measurement compensation system including: at least one electronic radiation source; at least one radiation shield; at least three reference detectors; and at least one borehole measuring radiation detector. A method of compensating the measurement of an electronic radiation source-based borehole logging tool that compensates for geometric variations in the direction output of an x-ray source is also provided, the method including at least: measuring an azimuthal distribution of radiation intensities equidistant from an electronic radiation source in order to correct a measured radiation value of a borehole-measuring radiation detector relative to the borehole-measuring radiation detector's azimuthal measurement direction.
