Health maintenance in elderly houses includes management of the gut microbiota and environment. Lacticaseibacillus paracasei Shirota (LcS) is a probiotic strain that positively affects human gut. However, evidence its effects on Indonesian population remains limited. To investigate effect LcS-fermented milk environment houses. This double-blind, randomized, placebo-controlled trial involved 112 participants from houses, spanning 2-week baseline 24-week treatment. Participants were randomly...
Abstract Objective. The purpose of this study is to propose a novel blurring correction method that enables accurate quantitative analysis the object edge when using energy-resolving photon counting detectors (ERPCDs). Although ERPCDs have ability generate various techniques, such as derivations effective atomic number ( Z eff ) and bone mineral density values, at in these images, information cannot be obtained. This because image prevents gathering primary x-ray attenuation information....
Energy-resolving photon counting detectors (ERPCDs) used for medical X-ray diagnosis have the potential to extract quantitative information concerning various organs. Previously, we proposed an analysis procedure determine effective atomic number (Z<sub>eff</sub>), but parameter optimization is required. The purpose of this study develop imaging simulator and derive optimal conditions. First, created taking into consideration following three elements: (1) attenuation in objects, (2) detector...
Abstract The eye lens is a sensitive organ of which an x‐ray exposure dose should be managed during interventional radiology (IVR). In the actual situations, exposed to scattered x‐rays; they have different from standard energies are used for general calibration dosimeter. To perform precise measurement, energy dependence dosimeter properly accounted when calibrating vendor supplies factor using 80‐kV diagnostic x‐rays under free‐air condition. However, whether it possible use this evaluate...
Purpose We aimed to develop a disposable rectum dosimeter and demonstrate its ability measure exposure dose the during brachytherapy for cervical cancer treatment using high‐dose rate 192 Ir. Our measures with an optically stimulated luminescence (OSL) sheet which was furled catheter. The catheter we used is 6 mm in diameter; therefore, it much less invasive than other dosimeters. developed this study has characteristics of being inexpensive disposable. It also easy‐to‐use detector that can...
Abstract Background Many healthcare institutions have guidelines concerning the usage of protective procedures, and various x‐ray shields been used to reduce unwanted radiation exposure medical staff patients when using x‐rays. Most are in form sheets lack elasticity, which limits their effectiveness shielding areas with movement, such as thyroid. To overcome this limitation, we developed an innovative elastic shield. Purpose The purpose study is explain methodology for developing evaluating...
Currently, an X-ray imaging system which can produced information used to identify various materials has been developed based on photon counting. It is important estimate the response function of detector in order accomplish highly accurate material identification. Our aim simulate a CdTe using Monte-Carlo simulation; at this time, transportation incident and scattered photons secondary electrons were precisely simulated without taking into consideration charge spread collecting process...
Energy-resolved photon counting detectors (ERPCD) are currently being developed for medical application. It is hoped that these can be used deriving precise material information. When purpose, many researchers concerned with the necessity to consider response of ERPCD analysis measured spectra. To solve this issue, we plan apply a correction incomplete energy signals using application software. For establishing procedure, should know in terms interactions between detector materials (Cd, Zn...
A photon counting system has the ability of energy discrimination, therefore obtaining new information using X-rays for material identification is an expected goal to achieve precise diagnosis. The aim our study propose a novel method based on technique. First, X-ray spectra at 40-60 kV were constructed published database. Second, penetrating different materials having atomic numbers from 5-13 calculated. These divided into two regions, then linear attenuation factors concerning these...
Energy resolved photon counting detectors have been developed and currently in use, we proposed practical methods for producing an X-ray image having effective atomic number information by means of plain diagnosis. An is hoped to be used enhance its value carry out more precise clinical In this study, aimed propose a novel material identification method using three energy bins detector. First, prepared theoretical spectra folded with the response function multi-pixel-type CdTe The was...
Currently, energy resolving photon counting detectors (ERPCD) are the focus of attention as a promising technique for material identification based on analysis X-ray energies. To accomplish highly accurate identification, consideration response multi-pixel-type ERPCD is important. This because detector distorts initial information which strongly related to such effective atomic number (Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">eff</sub>...
