A real-time photoacoustic imaging system is designed and built. This system is based on a commercially available ultrasound imaging system. It can achieve a frame rate of 8 frames/sec. Vasculature in the hand of a human volunteer is imaged, and the resulting photoacoustic image is combined with the ultrasound image. The real-time photo acoustic imaging system with a hybrid ultrasound probe is d...

As part of a large-scale noninvasive fetal ultrasound screen to recover ethylnitrosourea (ENU)-induced mutations causing congenital heart defects in mice, we established a high-throughput ultrasound scanning strategy for interrogating fetal mice in utero utilizing three orthogonal imaging planes defined by the fetus' vertebral column and body axes, structures readily seen by ultrasound. This co...

Technical advances in high-resolution ultrasound have brought ultrasound to the forefront of thyroid imaging. Despite the seeming similarity in the imaging appearance of diffuse thyroid diseases, the radiologist should be able to identify patients with diffuse thyroid abnormality, be aware of the spectrum of the imaging appearance of common thyroid conditions, suggest a clinically relevant diff...

Ultrasound imaging, one of the common diagnosis techniques, is frequently used since it safe, cost-efficient technique and real-time imaging can be conducted. However, various organs tissues reflect ultrasonic waves, which leads to difficulty in small biomolecules a low spatial resolution for deep-tissue images. As such, there have been significant advances photonics optical molecular probes re...
