Patient Vertical Centering and Correlation with Radiation Output in Adult Abdominopelvic CT.
Cheng PM. Cheng PM. J Digit Imaging. 2016 Aug;29(4):428-37. doi: 10.1007/s10278-016-9861-5. J Digit Imaging. 2016. PMID: 26810981 Free PMC article.
The purpose of this study was to determine if there is a significant effect, independent of patient size, of patient vertical centering on the current-modulated CT scanner radiation output in adult abdominopelvic CT. A phantom was used to evaluate calculation of vertical p …

Optics-on-a-chip for ultrafast manipulation of 350-MHz hard x-ray pulses.
Chen P, Jung IW, Walko DA, Li Z, Gao Y, Mooney T, Shenoy GK, Lopez D, Wang J. Chen P, et al. Opt Express. 2021 Apr 26;29(9):13624-13640. doi: 10.1364/OE.411023. Opt Express. 2021. PMID: 33985094 Free article.
Optical MEMS are developed for dynamic spatiotemporal control in lightwave manipulation and communication as modulators, switches, multiplexers, spectrometer, etc. However, they have not been shown to function similarly in sub-nm wavelength regimes, namely, with hard x-ray …

Image quality of conventional images of dual-layer SPECTRAL CT: A phantom study.
van Ommen F, Bennink E, Vlassenbroek A, Dankbaar JW, Schilham AMR, Viergever MA, de Jong HWAM. van Ommen F, et al. Med Phys. 2018 Jul;45(7):3031-3042. doi: 10.1002/mp.12959. Epub 2018 May 28. Med Phys. 2018. PMID: 29749624
In this study, we evaluate the influence of a dual-layer detector (IQon Spectral CT, Philips Healthcare) on the image quality of conventional CT images, by comparing these images with those of a conventional but otherwise technically comparable single-layer CT scanner (Brillia …

Ultra-brilliant GeV betatronlike radiation from energetic electrons oscillating in frequency-downshifted laser pulses.
Lu Y, Zhang GB, Zhao J, Hu YT, Zhang H, Li DA, Li QN, Cao Y, Wu YB, Yin Y, Shao FQ, Yu TP. Lu Y, et al. Opt Express. 2021 Mar 15;29(6):8926-8940. doi: 10.1364/OE.419761. Opt Express. 2021. PMID: 33820333 Free article.
The laser red shift originates from the phase modulation, together with the group velocity dispersion, which enables more energy to be transfered from the laser pulse to gamma-photons, giving rise to ultra-brilliant betatronlike radiation. Multi-dimensional particle-in-cel …
