Progresses of photoacoustic-ultrasonic combined imaging reconstruction / 中国医学影像技术

ABSTRACT

Ultrasonic computed tomography (USCT) and photoacoustic computed tomography (PACT) are two kinds of complementary imaging techniques. Photoacoustic-ultrasonic (PAUS) imaging combines PACT with USCT into one system and can obtain structural images and optical absorption distribution images of the target simultaneously. The combined images can display the acoustic discontinuity and optical absorption properties of the tissue. The diseased tissue can be accurately identified and located, and the functional components can also be quantitatively measured. The research progresses of the methods of joint images reconstruction for PAUS were reviewed in this paper.
