Time-gated imaging in planar and tomographic x-ray imaging

Gratz, M; Kiernan, L and Herrlin, K (1999) In Medical Physics 26(3). p.438-446
Abstract
Time-gated imaging is a new technique for scatter suppression in radiological imaging, based on the use of ultrashort x-ray pulses in combination with a fast gatable detector. We demonstrate scatter suppression in both planar and computed tomography (CT) radiography in an experimental model using x rays from a laser-produced plasma. The scatter-suppression efficiency of time-gated imaging is found to be similar to existing standard techniques. Furthermore, it allows for a potential decrease in patient dose. Monte-Carlo simulations confirm these results. We present an overview including theoretical simulations, experimental studies and comparisons to established techniques. The current technical limitations are evaluated and possible future... (More)
