Hologic shows a host of products and look at tomosynthesis
It’s been a year of mergers for Hologic, which provided the Bedford, Mass.-company with a full suite of offerings at RSNA 2007 last month in Chicago. In October, Cytyc stockholders approved their merger with Hologic, while earlier in the year Hologic had acquired BioLucent.

Hologic showed a breadth of products including the Selenia S digital mammography system that is specifically designed for the screening mammography facility or mobile environment. They also showcased the MammoSite targeted radiation therapy provides a higher daily dose that can be used for a shorter period of time. The SecurViewDX diagnostic workstation allows users to change their workflow with drag-and-drop ease. 

New to the company’s portfolio in 2007 is the MammoPad breast cushion. Designed for comfort, the radiolucent cushion's grip-like surface holds breast tissue in place to ensure optimal breast positioning for digital and analog mammography

In the CAD arena, the company showed the Hologic R2 CAD and the DigitalNow upgrade that digitizes films for soft-copy display so that prior screen-film images are displayed on the workstation along with the current digital images and can be sent to an archival system.

The company previewed Hologic’s 3-D Discovery Bone Densitometer. The work in progress uses a rotating C-arm on the Discovery system, allowing images of the femur to be acquired at different angles and 3D reconstruction. It is pending 510 (k) clearance.

With a look into the future, Hologic showed its investigational breast tomosynthesis system with a selenium-based detector. A specially designed booth was set up to provide visitors a chance to see a demonstration of how 2D and 3D imaging (breast tomosynthesis) can be accomplished.

Another work in progress is Hologic’s full-automated breast density assessment tool, Quantra. The new tool uses a complex model of the x-ray imaging chain to calculate the amount of dense tissue penetrated at each pixel in the image, which is independent of how the image was acquired. Using images from Selenia, Quantra gives the total volume of fibro-glandular tissue in cubic centimeters, as well as the total volume of the breast, removing the vagaries due to human estimation.
