Palpation Assessment Using Force Sensors

Force Sensing Incorporated into MammaCare^® PAD System

Background: MammaCare^® is the recognized medical and scientific standard for clinical breast examination efficiency. Developed with the support of the National Cancer Institute, this training platform is used in the US and Europe to teach health professionals to perform effective breast palpation. MammaCare’s overall goal is to reduce the incidence of missed palpable breast cancers, which are frequently not seen on imaging.

Challenge: Improving Current Sensor Sensitivities and Reducing Manufacturing Costs.  When MammaCare needed a more stable, durable, cost-effective tactile transducer for their PAD (Palpation Proficiency and Assessment Device) system, they turned to Tekscan. The PAD system is comprised of tactually accurate breast models, instrumented with FlexiForce sensors. The sensors locate and relay over 1000 levels of examination pressure within each square centimeter via a digital signal processor. This ability to quantify human palpation and lesion detection allows MammaCare to confidently certify whether clinicians have demonstrated appropriate examination skill. The novel training system is covered by both university and company patents.

Solution: The complete solution included a new sensor pad from Tekscan, and electronics, hardware, firmware, and Window drivers designed and provided by SSI Wireless. The ultra-thin force provided by Tekscan contained multiple force sensing points that enabled the system to confirm correct placement of the fingers, as well as the level of force applied by the fingers. The ideal solution also included no changes to the existing PC application and silicon models, and a full-featured product was delivered that helped keep costs within their budget.

 

"Work is spectacular. More exceptional than I thought it would be. Sensors work great. They can detect the slightest pressure accurately. It is WAY beyond my expectations."
