A revolutionary device has been developed by researchers at the University of Bristol that has the potential to transform clinical breast examinations (CBE) for women. The device, known as a manipulator, is designed to mimic human touch and can apply specific forces similar to those used by human examiners. It also incorporates sensor technology that can detect lumps at greater depths than previous methods.
The introduction of this device could revolutionize how women monitor their breast health. It would allow them to have access to safe and accurate electronic CBEs in easily accessible locations such as pharmacies and health centers.
Precision, repeatability, and accuracy are critical factors in ensuring positive patient outcomes during tactile medical examinations. While there have been previous attempts to use technology to improve CBEs, recent advances in manipulation and sensor technology have paved the way for more sophisticated devices.
The research team, supervised by Dr. Antonia Tzemanaki from Bristol Robotics Laboratory, utilized 3D printing and other techniques to create the manipulator. They conducted laboratory experiments using a silicone breast model and simulated experiments on its digital twin. These simulations enabled them to perform numerous palpations and test various scenarios, including the use of multiple sensors simultaneously.
Lead author George Jenkinson explained that the primary objective of the research was to determine whether a specialized manipulator could effectively palpate a realistic breast size and shape. The team has laid the groundwork for the development of such a device, with promising outcomes from the simulations and laboratory experiments.
The next phase of the research will involve combining CBE techniques used by professionals with artificial intelligence (AI) and equipping the manipulator with sensors. This will allow the team to evaluate the system’s effectiveness in identifying potential cancer risks.
The ultimate goal of the project is to enhance the accuracy and depth at which lumps can be detected, surpassing what can currently be accomplished through human touch alone. The device could also be integrated with existing techniques like ultrasound examinations.
George expressed hope that the research would contribute to the diagnosis of breast cancer and generate a wealth of data that could help identify trends for early detection. He also highlighted the potential to use the device as a low-risk means of objectively recording health data, facilitating comparisons between successive examinations and providing specialist referrals with comprehensive information.
Funded by Cancer Research UK and supported by EPSRC, this research forms part of the ARTEMIS project. The team presented their work at the RO-MAN conference.
In conclusion, this groundbreaking device has the potential to greatly improve the accuracy and accessibility of clinical breast examinations. By combining advanced technology with the expertise of healthcare professionals, it could aid in the early detection of breast cancer and significantly impact patient outcomes. The ongoing research and development of this device represent a promising step forward in breast health monitoring.
