A novel fiber in-line Mach-Zehnder interferometer (MZI) is demonstrated for temperature and refractive index measurements. The sensor is formed by splicing a section of etched thin core fiber (TCF) between two single mode fibers (SMFs). Experimental results show that, high temperature sensitivity of 198.5pm/°C with a temperature variation of 40 °C is achieved. The Refractive index (RI) response of...
In whole body PET scanners, extending the axial field of view (AFOV) can significantly increases the sensitivity. However, image axial resolution, which is an essential criterion in whole-body PET, may be especially affected by the depth of interaction (DOI) as the AFOV increases. In this paper, we use Monte Carlo simulations to find, in a long axial-FOV PET how DOI information affects the axial resolution...
In this study we proposed a novel design of the stationary multi-pinhole dedicated cardiac SPECT based on clinical dual-head scanner with high sensitivity and low cost for nuclear medicine myocardial perfusion imaging.
Online grocery shopping becomes more and more popular in recent years. To facilitate the purchase process, many online stores provide a shopping recommendation system for their consumers. So far, the generic recommendation systems mainly consider preferences of a consumer based on his/her purchase histories. Nevertheless, it is noted that there is nothing to do with the right timing to purchase a...
Background: Although clinical significance of serum p53 Abs (s-p53 Abs) in cancer patients has been studied during the past few years, how to detect it effectively is a crucial issue. Methods: wild-type p53 protein (wt p53) and phage-displayed peptide were prepared. Three types of enzymelinked immunosorbent assays (ELISA) methods were constructed and a hybrid antigen-ELISA approach was attempted....
