SPATIOTEMPORAL ANTIALIASING IN PHOTOACOUSTIC COMPUTED TOMOGRAPHY

摘要

A photoacoustic computed tomography method comprises acquiring photoacoustic data recorded by one or more data acquisition devices of a photoacoustic computed tomography system, applying location-based temporal filtering to the photoacoustic data acquired, wherein the location-based temporal filtering is based at least in part on geometry of the ultrasonic transducer array of the photoacoustic computed tomography system, and reconstructing one or more photoacoustic images from the filtered photoacoustic data.
