  • Patent number: 11622741
    Abstract: An X-ray source transmits X-rays through a subject and a detector receives the X-ray energy after having passed through the subject. A processing system generates a pre-shot image of the subject using low energy X-ray intensity from the X-ray source and determines a plurality of acquisition parameters for a main scan of the subject based on the pre-shot image. A saturation time of the detector for the corresponding acquisition parameters is determined based on detector calibration data and to determine a number of time frames required to reach the targeted dose based on the saturation time. An X-ray dosage level of the subject is then applied using the X-ray source based on the number of time frames and to generate the image of the subject based on the detected X-ray energy at the X-ray detector for the applied X-ray dosage level.

  • Publication number: 20230031814
    Abstract: Various systems are provided for non-uniform thickness and/or sampling of slabs of the breast to present DBT acquisitions. A method for generating a patient image as a set of slabs representing an imaged object, the method comprising acquiring a tomosynthesis projection, reconstructing a series of slab images, each slab representing a portion of a breast, and a plurality of slabs of non-uniform thickness and/or non-uniform sampling in a 3D reconstructed domain defined by x-, y-, and z-axes.

  • Publication number: 20220378390
    Abstract: A medical imaging system includes an X-ray source for transmitting X-rays through a subject and a detector for receiving the X-ray energy of the X-rays after having passed through the subject. The system also includes a processing system which is programmed to generate a pre-shot image of the subject using low energy X-ray intensity from the X-ray source and to determine a plurality of acquisition parameters for a main scan of the subject based on the pre-shot image. The processing system is also programmed to determine a saturation time of the detector for the corresponding acquisition parameters based on detector calibration data and to determine a number of time frames required to reach the targeted dose based on the saturation time.

  • Patent number: 11308594
    Abstract: Systems and methods for synthesizing a two-dimensional (2D) image of an organ of a patient by obtaining an pre-exposure x-ray image of the organ in order to ascertain parameters needed for acquisition of 2D (tomosynthesis) projection images of the organ, imaging the organ to obtain a plurality of 2D (tomosynthesis) projection images of the organ, and generating a synthetic 2D image of the organ from a combination of both the plurality of tomosynthesis projection images and the pre-exposure x-ray image.

  • Patent number: 10722187
    Abstract: A system for imaging is provided. The system includes an x-ray source, a detector, and a controller. The x-ray source is operative to transmit x-rays through a subject while the x-ray source continuously travels along a path defined by a sweep angle. The detector is operative to receive the x-rays after having passed through the subject. The controller is operative to: acquire preliminary data regarding the subject via the x-ray source and the detector; determine at least one acquisition parameter from the preliminary data; and acquire one or more projections of the subject via the x-ray source and the x-ray detector based at least in part on the acquisition parameter.
