Development and initial application of a fully integrated photoacoustic micro-ultrasound system.

Photoacoustic (PA) imaging for biomedical applications has been under development for many years. Based on the many advances over the past decade, a new photoacoustic imaging system has been integrated into a micro-ultrasound platform for co-registered PA-ultrasound (US) imaging. The design and implementation of the new scanner is described and its performance quantified.

A new 15-50 MHz array-based micro-ultrasound scanner for preclinical imaging.

Most institutions now have a suite of imaging tools to follow mouse models of human disease. Micro-ultrasound is one of these tools and is second after whole-mouse fluorescence or bioluminescent imaging, in terms of installed systems. We report in this paper the first commercially available array transducer-based ultrasound imaging system that enables micro-ultrasound imaging at center frequencies between 15 and 50 MHz.
