Abstract

We present photoacoustic computed tomography through an ergodic relay (PACTER), a method for single-shot 3D imaging of hemodynamics using a single-element detector. Our approach allows for ultrafast volumetric imaging at kilohertz rates without the need for numerous detector elements. We demonstrate PACTER in both human and small animal subjects, emphasizing its potential utility in early detection and monitoring of peripheral vascular diseases. Our single-element detector design aims to offer a more convenient and potentially affordable option, while the concept could also be relevant to other imaging technologies, contributing to various applications in medical imaging.
