Wearable Ultrasound Patch for Breast Imaging

This study is designed to evaluate the performance, safety, and reliability of a newly developed conformable wearable ultrasound (US) patch for whole-breast imaging. The device is a flexible, skin-adherent transducer array that provides real-time, three-dimensional imaging of the breast. The primary goal of the study is to assess the diagnostic accuracy of the US-patch device in detecting breast lesions across a variety of breast shapes, sizes, and tissue densities, using conventional handheld ultrasound as the reference standard (ground truth).

Investigators plan to enroll 50 patients over a 12-month period who are undergoing breast health evaluation and either have had or are scheduled for conventional breast ultrasound within one month. Participants will undergo imaging with the US-patch device, which will be applied directly to the breast and secured with a sports bra to maintain consistent contact. The imaging session will take less than 15 minutes and will be performed by trained study personnel.

The diagnostic performance of the US-patch device will be assessed by calculating sensitivity and specificity for breast lesion detection, using true positive, false positive, true negative, and false negative determinations based on radiologist interpretation. Statistical analyses will be performed on a per-lesion basis. Findings will be compared to conventional ultrasound results to determine the accuracy and reliability of the device.

Safety and tolerability will also be evaluated. All participants will be contacted by telephone one week after the imaging session to assess for any delayed adverse effects. Participants who return for follow-up visits within the one-year study period will undergo repeat US-patch imaging, and any adverse events, discomfort, or skin irritation will be documented.
