Sectra introduced its new L-30 MicroDose digital mammography system at RSNA’s annual meeting in Chicago last month. The company expects to apply for FDA approval in spring 2008 and in 2009 begin selling the units in the United States.
According to Jesper Söderqvist, president of Sectra Mamea AB, with the L30, a screening procedure takes just four minutes. The system utilizes a unique photon-counting technology which lowers dose and delivers high-contrast images. Photon-counting is the fastest detector technology on the market, Söderqvist said. The image is acquired by a multi-slit scanning technology that eliminates the scattered radiation and reduces the noise level of the image. Söderqvist said it produces less than 3 percent scattered radiation.
Söderqvist said the unit is designed for “better screening and patient care at the point of care.” According to Eva Edholm, radiology technician at Capio S:t Göran Hospital in Stockholm and a Sectra consultant, patients notice the difference. “They say, it is so quiet,” said Edholm, attributing it to the lack of electronic noise. The system easily adjusts for the different imaging positions which Edholm said eases the work for the techs.
Currently the L30 units are installed in 14 countries worldwide with units now shipping to the European market.
In 2008, Sectra will be participating in a three-year clinical study of tomosynthesis across eight sites in Europe, which Söderqvist said is the technology of the future for breast imaging.
