Among those parameters, the thickness of scintillator layer is very important and can be readily changed in fabrication. A thick scintillator layer can improve x-ray photon conversion efficiency but also degrade modulation transfer function due to a larger spatial blurring. It is proposed to optimise the selection of scintillator layer thickness for a better visualisation of small interventional devices. We applied quantitative experimental techniques and simulated three detector models including a direct detector and two indirect detectors. Two interventional devices, stent and guidewire, were investigated. Human observer experiments and computational model studies were conducted. Both of them demonstrate that the detection depends on the detector scintillator thickness and the structure of interventional device. At low x-ray exposures, a thick scintillator outperforms a thin scintillator in detection performance. A simulated direct detector has the least blurring in the images and hence gives even better detection performance for the stent detection. The thick indirect detector gives contrast sensitivities equal to those from the direct detector in the studies of guidewire detection and stent deployment.","PeriodicalId":216126,"journal":{"name":"Int.

Characterising the bubble dynamics, expansion and collapse is of importance in understanding the cavitation phenomenon and estimating the consequent outcome. In this study, Doppler ultrasound method was firstly used to measure the bubble wall velocity. Bubbles were generated in water using a beam of high-intensity focused laser light or inside a vessel phantom using a shock wave generator. Agreement was found between the determination by high-speed photographs and Doppler method. Overall, it is suggested that Doppler ultrasound could be a noninvasive method of quantitatively detecting bubble dynamics in vivo.","PeriodicalId":216126,"journal":{"name":"Int. J. Funct.

The collected set of context data may be transmitted to a monitoring centre and also interpreted locally using medical knowledge; the identification of a patient's abnormal condition can activate local actions or send an emergency message to a monitoring centre. This infrastructure can help a doctor to monitor and assist the patient while he or she is performing daily activities and may also help improving the patient's treatment compliance and quality of life.","PeriodicalId":216126,"journal":{"name":"Int.

It is, therefore, concluded that YinYang and TCM researchers are obligated to make an effort to use some 'pure thought' to grab the reality in mathematical terms instead of only trying to 'distill' the principles from 'experience' or, alternatively, only trying to fit TCM into western medicine.","PeriodicalId":216126,"journal":{"name":"Int.

Faced with these tough choices, this paper unveils the salient nature of YinYang related to Greek philosophy and identifies its critical role in logic, TCM, and modern science. Surprisingly, it is shown that YinYang bipolar relativity has opened an eastern road toward quantum gravity – Einstein's unfinished scientific unification of general relativity and quantum mechanics. Furthermore, it is shown that not only does YinYang bipolar quantum gravity constitute a physical theory but also a mental, logical, social, and biological quantum theory.","PeriodicalId":216126,"journal":{"name":"Int.
