Photoacoustics (PA) is a new imaging modality based on the generation of ultrasound due to laser irradiation. Instead of commonly used Q-switched Nd:YAG lasers the application of pulsed laser diodes as light sources for photoacoustic imaging is proposed. The high pulse repetition frequency of laser diodes enables the usage of coded excitation schemes for SNR improvement. Therefore, the performance...
Photoacoustics (PA) combines the high contrast of optical imaging modalities with the high resolution of clinical ultrasound. Fluorescence mediated tomography (FMT), on the other hand, offers a very high molecular contrast specificity. Therefore, a combination of PA imaging and FMT might be fruitful: e.g. PA imaging could provide valuable a priori information for optical-tomography reconstruction...
