  • X-ray breast tomosynthesis enhancing spatial resolution including in the thickness direction of a flattened breast
    Patent number: 10792003
    Abstract: Systems and methods for breast x-ray tomosynthesis that enhance spatial resolution in the direction in which the breast is flattened for examination. In addition to x-ray data acquisition of 2D projection tomosynthesis images ETp1 over a shorter source trajectory similar to known breast tomosynthesis, supplemental 2D images ETp2 are taken over a longer source trajectory and the two sets of projection images are processed into breast slice images ETr that exhibit enhanced spatial resolution, including in the thickness direction of the breast. Additional features include breast CT of an upright patient's flattened breast, multi-mode tomosynthesis, and shielding the patient from moving equipment.

  • Integrated breast X-ray and molecular imaging system
    Patent number: 8217357
    Abstract: An integrated tomosynthesis/molecular breast imaging device having improved sensitivity includes tomosynthesis imaging components and molecular breast imaging components. The imaging components may be used individually or in combination to provide a system with improved sensitivity and specificity. Molecular imaging components may be smoothly advanced or withdrawn depending upon the desired imaging mode. The system supports both PET and SPECT imaging and enables SPECT collimation to be modified in accordance with image capture requirements.

  • Breast tomosynthesis system with shifting face shield
    Patent number: 7792245
    Abstract: Breast imaging using any one of a mammography system, a tomosynthesis system, or a fused system that selectively takes either or both of mammography images and tomosynthesis images, further uses a patient shield that moves closer to and further away from the patient's chest and head, between (1) an access position that facilitates the technologist's access to adjust the patient's breast while the breast is being compressed and (b) a protective position in which the shield helps protect the patient from collision with moving components and from x-ray exposure of tissue other than the tissue that is to be imaged.
