Trellis-Coded Balanced Space-Time Block Code Selection

2007 IEEE 15th Signal Processing and Communications Applications, 2007
In this paper, a trellis coded balanced space-time block code selection scheme (TC/BSTBCS) which is obtained by using balanced space-time block code selection (BSTBCS) with super-orthogonal space-time trellis coding (SOSTTC) is proposed for wireless communication.

High spatial resolution dosimetry for radiation oncology with “MagicPlates,” a new 976‐pixel monolithic silicon detector

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose We introduce the next generation of “MagicPlate” 2D monolithic pixelated semiconductor detectors – MagicPlate‐976 (MP976). It features a larger array area, higher spatial resolution, and does not require external triggering. We perform a comprehensive characterization for small‐field steep‐dose‐gradient dosimetry applications in ...

Evaluation of the dose reduction effect of crystalline lens exposure in cone‐beam computed tomography with bismuth eye shield for image‐guided radiation therapy: An anthropomorphic phantom study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract This study aimed to evaluate the dose‐exposure reduction effect of a crystalline lens with a bismuth eye shield using cone‐beam computed tomography (CBCT) for head image‐guided radiation therapy. The ocular surface dose of the head phantom (THRA‐1) is defined as a crystalline lens exposure dose and is measured using a radiophotoluminescence ...
