Title: 4D spatiotemporal evolution of liquid spray using kilohertz-rate x-ray computed tomography

Abstract

Four-dimensional (x, y, z, t) x-ray computed tomography was shown in an optically complex spray using an imaging system consisting of three x-ray sources and three high-speed detectors. The x-ray sources consisted of high-flux rotating anode x-ray tube sources that illuminated the spray from three lines of sight. The absorption along each absorption path was collected using a CsI phosphor plate and imaged by a high-speed intensified CMOS camera at 20 kHz. The radiographs were converted to a quantitative equivalent path length (EPL) of liquid using a variable attenuation coefficient to account for beam hardening. Moreover, the EPL data were then reconstructed using the algebraic reconstruction technique into high-speed time sequences of the threedimensional liquid mass distribution.
