Abstract
Real-time ultrasound/photoacoustic in-vivo imaging will be demonstrated using a portable, dual-modality photoacoustic and ultrasound imager that features a pulsed diode laser integrated into an hand-held ultrasound probe. The 800-nm-wavelength diode provides 0.6 mJ pulses after the probe aperture in a 20 mm × 4 mm rectangular beam and can be fired at 210 Hz, limited by the Maximum Permissible Exposure. In-vivo imaging that will be demonstrated will include finger-joint imaging for future early detection of inflammation in rheumatoid diseases. New photoacoustic techniques that might increase the sensitivity of the detection of inflammation, such as PA Doppler, will also be discussed.
