Evaluation: Hologic Selenia Dimensions with Genius Mammography System with Tomosynthesis

October 26, 2016 | Evaluations & Guidance


  • The Selenia Dimensions with Genius provides 2-D and 3-D images of the breast for screening or diagnostic imaging of breast cancer. In tomosynthesis (3-D) mode, the system generates a series of 2-D images through the breast. Each screening examination may consist of a 2-D full-field digital mammography (FFDM) image set or a 2-D+3-D image set. This system can synthesize the 2-D image from the 3-D image set.
  • Supplementary uses of the device are diagnostic procedures and stereotactic breast biopsy.
  • Major device components and software features:
    • Motorized gantry
      • The swivel range is -155° to +195° with preselectable rotation angle; for biopsy and tomosynthesis, the rotation angle is -140° to +180°.
      • The height adjustment is 71 to 142 cm.
    • X-ray tube and generator
      • Source-to-image (detector) distance (SID): 70 cm
      • kV range: 20 to 49 kV in 1 kV increments
      • Power output: 7 kW
      • Target/filter options: (a) In 2-D mode: W/Rh; W/Ag
