MIT Develops Portable Ultrasound Device for Early Breast Cancer Detection
MIT researchers have created a compact ultrasound system designed to facilitate more frequent breast cancer screenings, potentially enabling earlier detection and treatment.
MIT researchers have developed a portable ultrasound system aimed at enhancing early detection of breast cancer, particularly for individuals at high risk. The device comprises a small ultrasound probe connected to a processing module slightly larger than a smartphone, capable of generating real-time 3D images when linked to a laptop.
Associate Professor Canan Dagdeviren, the study's senior author, highlighted the system's compactness, noting its potential to improve accessibility in rural areas and for individuals facing technological barriers. She emphasized that earlier tumor detection could significantly increase the chances of successful treatment.
Traditional ultrasound machines are often large, expensive, and require skilled technicians, limiting their use in certain settings. The new system addresses these challenges by being portable and user-friendly, potentially enabling more frequent screenings outside conventional medical facilities.
The device features a chirped data acquisition system (cDAQ) with an ultrasound probe containing an array arranged in an empty square configuration, allowing for comprehensive 3D imaging. The processing module, costing approximately $300 to produce, utilizes commercially available electronics and can be powered by a standard 5V DC supply.
Initial testing on a 71-year-old woman with a history of breast cysts demonstrated the system's ability to accurately image cysts and create gap-free 3D representations of breast tissue. The researchers are now conducting larger clinical trials and working on a smaller version of the processing system, aiming to integrate it with smartphones for enhanced portability and ease of use.
The research received funding from the National Science Foundation CAREER Award, a 3M Non-Tenured Faculty Award, the Lyda Hill Foundation, and the MIT Media Lab Consortium.
