A Novel Static CT System: The Design of Triple Planes CT and Its Multi-Energy Simulation Results

Abstract

In this paper, we propose a novel static CT system: triple planes CT (TPCT) system. Three source-detector planes in different horizontal directions are placed in the system. Line-array carbon nanotube sources with different voltages and sandwich detectors are used. Compared to conventional cone-beam CT and common inverse-geometry CT, the TPCT enables fast scanning and six-energy imaging. 1-D U-Net is applied to correct the severe scatter caused by the special geometry. The limited-view problem is solved by the hybrid reconstruction algorithm. A Monte-Carlo simulation is performed on a thorax phantom. Both the reconstruction results and decomposition results have good image quality and show the feasibility of our proposed TPCT imaging system.

Optimization of a multi-source rectangular x-ray CT geometry for inline inspection

“…health innovation. 9,11,12,[14][15][16][17] The X-ray foci were evenly distributed throughout the array to maximize the coverage area and were scanned sequentially to obtain multi-view projections. 9,16 Intuitively, this equidistant distribution is the natural choice (unless there is prior knowledge of the objects to be inspected).…”
