As early as possibleFrom bull-sized X-ray machines to special systems for mammography

Philip Strax trägt wesentlich dazu bei, der Mammographie zum Durchbruch zu verhelfen

Philip Strax played a key role in helping mammography achieve its breakthrough into clinical practice.

All of the stories from the early days of X-ray technology feature brilliant and often even fascinating characters. Their pioneering research was sometimes triggered by an ingenious idea, sometimes by a groundbreaking discovery, and sometimes – as in the case of the radiologist Philip Strax – by a situation in the researcher’s personal life. Strax was a general practitioner running a small practice in Manhattan when he and his family received some shocking news: His wife, Bertha Goldberg Strax, had developed breast cancer, and died at the age of 39 in 1947. Philip Strax resolved to spend his life’s work preventing that kind of shock from happening to anyone else, especially the patient.


In 1963, Strax and his team began searching for the best way of detecting breast cancer as early as possible so that radical surgery could be avoided. Their research centered around a mass screening of some 62,000 New York women, which represented a huge logistical undertaking right from the outset. Most of the hospitals were in the north of the city in those days, and many women were not prepared to travel the long distances required. Undeterred, Strax began personally calling and writing the women to persuade them to take part. The team eventually outfitted a van with an X-ray machine, parked it alongside the ice-cream trucks and sandwich vendors in Midtown Manhattan, and examined subjects in their lunch breaks.

To allow participating hospitals to perform several thousand mammograms a day, the women were channeled through a carousel-like structure made up of multiple changing cubicles. This process went on all day and late into the evening, and was planned down to the last detail – from the stops on the route to the time that people entered the cubicles and even how much time they had to dress and undress. “To expedite turnover, the amenities of chairs and mirrors [were] omitted.” This was the largest study yet into the benefits of mammography, and it resulted in the timely detection and treatment of tumors in a number of women, with almost 40% fewer deaths from breast cancer among the screening participants than in the control group. An ecstatic Strax wrote: “The radiologist has become a potential savior of women – and their breasts.”

The first “real” Siemens mammography system in 1972

In the MAMMOMAT system (1972), the X-ray tube, cone, and X-ray film were fixed to one another as part of a “mammography unit.”

In the mid-1960s, when mammography was still in its infancy, only a handful of highly experienced specialists were using “machines the size of a full-grown bull” to create images of their patients’ breast tissue. This fledgling diagnostic technique required a great deal of skill on the part of the operator and placed extraordinary demands on the technology. Even at that time, however, it was clear that mammography would become an increasingly important tool for cancer screening in the future. With this in mind, a number of Siemens engineers stated in 1971: “We believe it is necessary to develop a special mammography device that allows quick and easy operation while also producing optimum image quality.” The Siemens MAMMOMAT system eliminated the need for tedious configuration and adjustment of the X-ray equipment and featured an X-ray tube optimized for breast diagnostics, allowing physicians to visualize tiny structures in the tissue down to a size of 0.1 millimeters. “With MAMMOMAT, a device [was] now available that, thanks to its easy operation and above all to the high image quality that it [could] achieve and the low radiation load for the patient, [was] suitable for the cancer screening examinations that are generally recognized as urgent.”

Im Jahre 2008 sind weltweit 34 „Mammo-Mobile“ rund um den Globus unterwegs

In 2008, 34 “mammomobiles” were out and about around the world

Based on our first MAMMOMAT, our company went on to shape the field of mammography by developing a whole series of new technologies. Over time, increasing automation and digitalization have influenced almost every aspect of the MAMMOMAT family. In addition to the development of major milestones such as tomosynthesis, which has allowed three-dimensional imaging of the breast since 2009, we also engage in numerous initiatives aimed at informing people about the importance of early detection. Some 45 years after Philip Strax first screened women for breast cancer during their lunch breaks in a van in Manhattan, there are now “mammomobiles” out and about in several countries around the world. These mobile mammography units incorporate a small but fully functional examination room equipped with a Mammomat Inspiration. With the introduction of the mammomobiles in 2008, Siemens hoped to give women in rural areas the opportunity to learn about breast cancer and to be examined there and then if they wished.

„Turn your city pink!“ – Collage nach einem Jahr Kampagne mit tausenden Fotos aus 76 Ländern

A collage of thousands of photos from 76 countries following a year-long campaign entitled “Turn your city pink!”

Between October 2011 and October 2012, a campaign entitled “Turn your city pink! Raise awareness for breast cancer” saw participants in 76 countries produce thousands of photos and videos with a view to disseminating the central idea of the campaign in the most creative and public ways possible. The aim of the initiative was to encourage people around the world to engage with the topic of early detection and to join the campaign themselves.
