Abstract
In this presentation, we introduce the initial patient imaging results of our dual-scan mammoscope system. The goal is to verify whether the system can differentiate malignant and healthy cases. We have imaged 38 patients with various cancer types and compared results of tumor breast with healthy breast for each patient. At 95% confidence level, we found that tumor breasts exhibit higher average photoacoustic signal amplitude, higher vessel signal amplitude, and stronger variation in background signals. We could also visualize different vascular features in and around the tumor region for different subtypes of tumors. Our preliminary results indicate that photoacoustic technology has a high potential for breast imaging.
