Engineered by women for women: Colleagues band together to take fear out of breast screening

Study after study has shown that detecting breast cancer early can dramatically improve the chance of healing and survival1. “Mammography has been proven to reduce mortality by 20 percent2,” says Claire Goodliffe, marketing director for women’s health at GE Healthcare. But another, less promising set of statistics haunts Goodliffe: As many as 40 percent of women in Europe and 30 percent in the U.S. skip screening3. “They are afraid,” Goodliffe says. “They are afraid of the examination, they are afraid of the pain they may feel, and they are afraid of the results. They are afraid of getting cancer.”

That’s why Goodliffe and her colleagues at GE Healthcare’s campus in Buc, just outside of Paris, set out on a quest to design a mammography machine that wouldn’t scare people. “My design philosophy is to mix science with empathy,” says industrial designer Aurelie Boudier, who joined Goodliffe on the project. “We wanted to build a machine that changed the subjective perception of the mammogram and spoke to the woman to make her feel reassured.” Adds Goodliffe: “We wanted to humanise the examination.”

The project was unusual because like Goodliffe and Boudier, many of the engineers, designers and managers involved in building and manufacturing the machine were women. “We wanted to put the woman at the heart of the project,” says Laura Hernandez, global product manager for the Senographe Pristina, as the machine is called. “This is engineering by women for women.”

Mammography has been around since the 1960s, when French engineers Jean Bens and Emile Gabbay developed a breast-dedicated X-ray machine with a special X-ray tube that emitted low-energy radiation and still allowed doctors to see breast tissue in greater detail. They called their machine the Senographe and brought it to market in 1966. GE Healthcare, which acquired Bens and Gabbay’s company in 1987, has been making mammography systems ever since.

But some three decades later, Goodliffe and her colleagues sensed the mammography needed more than a technology upgrade to break down the emotional barriers that kept women from getting mammograms.

They started by gathering insights from over 1,200 doctors, technicians and patients and 25 clinics. One recurring issue was discomfort tied to the design of the screening systems. During the exam, women place their breasts on a platform the size of a laptop called the bucky, stretch out their arms and support themselves by holding onto handles located on the body of the machine. Older machines typically have angular, metallic buckies that can feel cold and painful. “My reaction [during an exam] is that I want to step back,” says Hernandez, echoing many of the patients the team surveyed.

Doctors, on the other hand, wanted to do away with the handles because grasping them caused patients to flex their pectoral muscles and tense up during the exam. “They wanted the women to relax,” Boudier says.

She took the survey findings and started building a mock-up of a new machine in the design lab at Buc. Fanny Patoureaux from the engineering team then brought Boudier’s design to life, fitting inside the machine’s sleek body advanced imaging technology that allows doctors to see the breast in 2D and 3D slices and “read it like a book.” One application even helps them build a “synthetic view” of the breast inside a computer and then use deep learning algorithms to help physicians pinpoint suspicious areas. “We needed to blend all of this high technology with design features that conveyed emotional benefits,” Patoureaux says.

It was a challenge, she admits, but working closely with Boudier allowed the team to “chip away at the anxiety women experience during a mammography exam while providing pristine image quality for accurate diagnoses.”

Another key consideration was manufacturing, since the design also had to be easy to produce. “We were involved very early in the process,” says Beatrice Martin, who now runs the Pristina production line in Buc. Borrowing from GE’s “brilliant factory” principles, she and her team were able to reduce the assembly time by half, compared to previous systems.

As they moved along, the team invited groups of women to test Boudier’s prototypes and provide more feedback. The final design has a thin, black bucky with smooth round edges made from a carbon fiber composite. The material provides a warm surface “so women won’t move during the exam,” Hernandez says. “We have also designed a new remote control so women can compress their breast with the aid of a technician, a first in the industry*.”

Boudier also replaced the handles with armrests and LED lights that encourage women to relax during the exam. “It’s almost spa-like,” Hernandez says.

The main pillar of the machine, which holds the X-ray source, features flowing, overlapping plastic folds meant to symbolize a shawl. Its concave shape allows patients to rest their head against it. “From the beginning, I kept in mind a woman who is feeling anxious and wraps a cover over her shoulders to feel safe,” Boudier says. “I wanted to express that feminine gesture and keep it a metaphor for our design approach.”

Pristina is now available in most parts of the world, and some customers, like the Gustave Roussy Cancer Center in Paris, have fuchsia-painted Pristina rooms where soothing music plays in the background. The latest design for the scanner now also offers an option for hospitals to hide much of the support structure in a wall and blend it with the surroundings.

Last December, Goodliffe went to get her own Pristina mammogram at a clinic in central Paris. “I wanted to feel what other women were going through,” she says. When she arrived at the appointment with her small daughter, the girl wanted to know why her mother was so interested in the machine. “Well, you know, what I do,” Goodliffe said. “I help women take care of their boobies.”
