The World Health Organization reported that in 2020, 2.3 million women worldwide were diagnosed with breast cancer. American Cancer Society states that early diagnosis of breast cancer leads to a 100% survival rate. During the initial diagnosis, images or scans of breast tissue are examined by the doctor to detect abnormalities.
Doctors commonly use ultrasound devices to diagnose breast cancer using sound waves. Ultrasound for diagnosing breast cancer. Scientists have identified limitations of ultrasound in the past, such as the need for proper skills and training, poor contact with skin during scanning, and maintenance challenges of large ultrasound machines in hospitals.
To address these limitations, a group of researchers developed a wearable, portable, and affordable device called cUSBr-Patch, which stands for Compatible Ultrasonic Chest Patch. To create this wearable patch, they used a 3D printer to design a honeycomb-shaped patch with holes that can be attached to a soft fabric bra.
Scientists attached a small scanning device to the patch that uses sound waves to acquire medical images similar to an ultrasound machine. This device, called phased array transducer, uses piezoelectric material and differs from traditional hospital ultrasound scanners, producing clear and high-resolution images.
The cUSBr-Patch is attached to a bra with magnets and allows the patch to directly touch the skin for scanning. A small tracker on the phased array transducer is moved and rotated using a handle to capture images of the entire breast.
Researchers tested cUSBr-Patch on female patients with breast abnormalities, scanning both breasts in six different locations using the phased array transducer connected to the patch. Computer programs were then used to generate images similar to those from standard hospital ultrasound machines.
The researchers concluded that cUSBr-Patch can detect breast cancer at a level comparable to traditional hospital ultrasound equipment. They are working on a smaller version of the device, aiming to make it accessible for home use by high-risk individuals and populations without regular testing facilities to improve breast cancer survival rates significantly.
