Paper Abstract

We describe the ongoing development and performance of a high-pulse-energy wavelength-cycling laser system for three-dimensional optoacoustic tomography of the breast. Joule-level energies are desired for achieving the required penetration depths while maintaining safe fluence levels. Wavelength cycling provides a pulse sequence which repeatedly alternates between two wavelengths (approximately 756 and 797 nm) that provide differential imaging. This improves co-registration of captured differential images and quantification of blood oxygen saturation. New design features have been developed for and incorporated into a clinical prototype laser system, to improve efficacy and ease of use in the clinic. We describe the benefits of these features for operation with a clinical pilot optoacoustic / ultrasound dual-modality three-dimensional imaging system.
