Hologic Improves Radiation Therapy, Reduces Hospital Stay

Hologic will demonstrate MammoSite, a targeted radiation therapy solution that works from the inside, meaning that a higher daily dose can be used for a shorter period of time, five days versus five to seven weeks. MammoSite places the radiation source inside the lumpectomy cavity, delivering radiation to the area where cancer is most likely to recur. The therapy is given on an outpatient basis. No hospital stay is required.

The company will also highlight new features of the Selenia S digital mammography system, a product specifically designed for the screening mammography facility or mobile environment. Selenia S uses the Hologic direct conversion detector, eliminating the need to convert X-rays to light, producing a sharp digital image reportedly with better contrast and detail.

The new tungsten X-ray tube option for Selenia is a tungsten tube in combination with a special silver filter and allows images to be acquired at a lower dose without compromising the superb image quality of Selenia. The silver filter’s intended use is for imaging thicker breasts with both lower dose and shorter exposure times to eliminate problems with patient motion.

Hologic is reportedly the first company to introduce the use of the silver filter with a tungsten tube in digital mammography. Systems shipped with the tungsten tube option will be calibrated to have a minimum of 30 percent reduction in dose, for a 4.5-centimeter breast, compared to Selenia/Molybdenum systems. Users have the option of choosing even lower dose settings, based on individual site preferences.
