We reported an initial clinical study of in vivo human thyroid by a photoacoustic/ultrasound handheld probe. Our dual-modality system is based on high-end ultrasound machine. Both healthy and cancerous thyroids were imaged non-invasively, we compared the photoacoustic imaging with color Doppler ultrasound. The results could reveal many blood vessels that not sensitive for demonstrated provide important complementary information traditional examination, which has great potential diagnosis.

We examined 14 benign and 26 malignant breast nodules by a handheld dual-modal PA/US imaging system analyzed the data using quantitative semi-quantitative method. The PA signal spatial density scores of different regions were compared, diagnostic performances two methods based on parameters evaluated. For both results, significant differences in distributions signals lesions identified. showed good performance diagnosing cancer, indicating potential PAI clinical utilization.

Abstract In this pilot study, we explored a quantitative method to analyse characteristics of breast tumours using 3D volumetric data obtained from three-dimensional (3D) photoacoustic/ultrasound (PA/US) functional imaging system. Imaging results 24 Asian patients with maximum tumour diameters less than 2 cm, including 8 benign tumours, 16 T1 stage invasive cancers (IBCs), and 22 normal breasts, were analysed. We found that the mean oxygenation saturation (SO ) in regions IBCs was 7.7% lower...
