Among the differences between previous 3D tomography technology and the Senographe Pristina, says O’Connor, “is that this is a purpose-built machine — it hasn’t had 3D cobbled onto it”.Importantly, he says that the acquisition of submillimetre image slices of the breast, and subsequent submillimetre accuracy in reconstruction of the 3D view using GE’s ASi R iterative reconstruction algorithm, result in much clearer visualisation of breast abnormalities than was previously possible, with superior reduction of distracting artefacts.The reconstructive algorithm then “synthesises” these images into a set of three-dimensional views in which tissue overlap is minimised.
“We compress the breast to a minimum diagnostic thickness of 3cm to 4cm, and then we say to the woman, ‘Every Newton of extra pressure we get will increase our diagnostic sensitivity and specificity.’” Studies have shown and O’Connor’s experience confirms that, on average, patients will apply an extra 30% of pressure when thus engaged in the acquisition of their mammograms O’Connor adds that although the Pristina gathers a more detailed and comprehensive set of images, the ergonomics of the machine from an operator perspective, and the intuitive and sensitive design of the machine as experienced by patients, actually reduces the time needed to position each woman and acquire images.
For Coastal Medical Imaging that means more time spent engaging with patients and understanding their medical history and circumstances.
O’Connor identifies Pristina’s soft-plastic face shield as a particularly inspired design element, the use of which is intuitive to patients and helpful to technologists: “You lean your face into it, and its positioning means you and the technician don’t have to worry about your face blocking the image acquisition.” “We wanted to build a machine that changed the subjective perception of the mammogram and spoke to the woman, to make her feel reassured,” says industrial designer Aurelie Boudier, one of the women on the team that developed Pristina.
Insights from more than 1,200 doctors, technicians and patients surveyed by GE suggested that willingness to return for regular mammograms is affected by women’s initial experience of compression of their breasts to achieve what’s known as a minimum diagnostic thickness.
Purpose built for 3D-image acquisition Senographe Pristina is purpose designed to reshape the mammography experience, taking into account women’s feedback on screening to date.
The result is a uniquely appealing-looking system — slim line, not monstering; curved, not hard edged — that allows technicians to set up the patient for imaging in a more empathetic way — face to face and with easy access for the technician to every part of the machine.
GE has developed a paddle that has flexibility, resulting in much less of that shearing effect, but which still gives good compression.” Pristina’s soft armrests which replace the more common hand grips, also help women to relax their muscles, easing discomfort and aiding clear image acquisition.
Sharing control enhances imagery The addition of Senographe Pristina Dueta, a remote control that allows women to determine the pressure applied for compression, again improves women’s experience and delivers better images.
