- Abstract
- Recently, 3D photoacoustic (PA) and ultrasound (US) technologies have been developed in various forms. There are roughly two main streams to obtain a 3D image; an 1D array US transducer with motorized scanner and a 2D matrix array US transducer. The former has limitations such as longer time to obtain a single 3D image, bulky design with the scanner that degrades portability, and anisotropic resolution. In contrast, the latter acquires and generates a 3D image at once, which enables real-time imaging, compact design, and isotropic resolution. In this study, we demonstrate dual-modal PA and US imaging using a 2D matrix array transducer scanner. The resolution was measured through a phantom experiment, and the methylene blue signal was verified through a rat SLN experiment. © 2022 SPIE.
