Hologic, at SIIM 2007 in Providence, R.I., last week, showed a work-in-progress digital tomosynthesis tool for its Selenia digital mammography system that the company hopes to launch around the time of the RSNA annual conference this fall. Generally speaking, digital tomosynthesis takes multiple x-ray images of the breast from an assortment of angles. In the instance of the Hologic developmental system, which would be displayed on the company’s SecurView diagnostic workstation, a physician is given a view that is much like “taking a trip through the breast slice by slice,” according to a company representative at the show.
Other currently available systems on the show floor included the R2 DigitalNow systems which are able to digitize prior images and send them directly into PACS. The systems can scan any mammography film, up to 24 films per study including spot compression and magnification views. DigitalNow also adds DICOM headers for integration with automated hanging protocols on a mammography workstation.
