TY  - JOURAB  - A laser-wakefield driven x-ray source is used for the radiography of human bone. The betatron motion of accelerated electrons generates x-rays which are hard (critical energy ${{E}_{\text{crit}}}>30$  keV), have small source size (<3 μm) and high average brightness. The x-rays are generated from a helium gas cell which is near-instantly replenishable, and thus the average photon flux is limited by the repetition rate of the driving laser rather than the breakdown of the x-ray source. A tomograph of a human bone sample was recorded with a resolution down to 50 μm. The photon flux was sufficiently high that a radiograph could be taken with each laser shot, and the fact that x-ray beams were produced on 97% of shots minimised failed shots and facilitated full micro-computed tomography in a reasonable time scale of several hours, limited only by the laser repetition rate. The x-ray imaging beamline length (not including the laser) is shorter than that of a synchrotron source due to the high accelerating fields and small source size. Hence this interesting laboratory-based source may one day bridge the gap between small microfocus x-ray tubes and large synchrotron facilities.AU  - Cole,JMAU  - Wood,JCAU  - Lopes,NCAU  - Poder,KAU  - Abel,RLAU  - Alatabi,SAU  - Bryant,JSJAU  - Jin,AAU  - Kneip,SAU  - Mecseki,KAU  - Parker,SAU  - Symes,DRAU  - Sandholzer,MAAU  - Mangles,SPDAU  - Najmudin,ZDO  - 1/014008PY  - 2016///SN  - 1361-6587TI  - Tomography of human trabecular bone with a laser-wakefield driven x-ray sourceT2  - Plasma Physics and Controlled FusionUR  - http://dx.doi.org/10.1088/0741-3335/58/1/014008UR  - http://hdl.handle.net/10044/1/29629VL  - 58ER  -
