In this work, we report the experimental observation of supercontinua generation in two kinds suspended-core microstructured soft-glass optical fibers. Low loss, highly nonlinear, tellurite and As2S3 chalcogenide fibers have been fabricated pumped close to their zero-dispersion wavelength femtosecond regime by means an parametric oscillator a Ti:Sapphire laser. When coupled into fibers, pulses result 2000-nm bandwidth reaching Mid-Infrared region extending from 750 nm 2.8 µm 1 3.2 respectively.
Unresectable malignant bile duct stricture (often caused by unresectable pancreatic cancer and cholangiocarcinoma) can be drained via insertion of self-expandable metal stents (SEMS) during endoscopic retrograde cholangiopancreatography (ERCP). Because recurrent biliary obstruction (RBO) complications following stent delay chemotherapy other treatments, a longer time to RBO (TRBO) is desirable. Although TRBO has been reported among patients who undergo with larger diameter SEMS, smaller...
We present the case of a 49-year-old woman with autoimmune hepatitis and persistent jaundice. On admission, pathology laboratory results supported diagnosis hepatitis-primary biliary cholangitis (AIH-PBC) overlap syndrome vanishing bile duct (VBDS). Standard treatment, including methylprednisolone pulse therapy, prednisolone, azathioprine, bezafibrate, ursodeoxycholic acid, failed to resolve In addition jaundice, patient also had constipation regularly used magnesium oxide sennoside....
Abstract The purpose of this study is to evaluate the physical image quality a commercially available image‐based iterative reconstruction (IIR) system for two object contrasts resemble soft tissue (60 HU) and an enhanced vessel (270 HU), compare results with those filtered back projection (FBP) (IR). A 192‐slice computed tomography (CT) scanner was used data acquisitions. IIR images were processed from FBP images. Task‐based in‐plane transfer function (TTF) slice sensitivity profile (SSP...
Two ultra-high-resolution (UHR) computed tomography (CT) scanners are clinically available. One is achieved by a CT system with 0.25 mm × 160 row detector (Detector-UHR), whereas the other 0.6 32 in-plane comb filtering in dual source (Comb-UHR). We compared radiation dose efficiencies of two UHR modes to that routine scan mode (RS), using physical image quality measures for an assumed condition abdominal angiography (CTA).A wire phantom, 300-mm cylindrical water bath and microdisk phantom...
The aims of this study were: 1) to determine whether the accumulation aortic root calcification (ARC) assessed using coronary computed tomography angiography (CCTA) can predict future cardiovascular events, and 2) estimate onset progression ARC in patients with familial hypercholesterolemia (FH).One hundred thirteen consecutive Japanese heterozygous FH (male=54, mean age=52.1±15.6 years, LDL-C=299.0±94.6 mg/dL), without known artery disease, who underwent 64-detector row CCTA were...
Purpose: To assess the physical performance of deep learning image reconstruction (DLIR) compared with those filtered back projection (FBP) and iterative (IR) to estimate dose reduction potential technique. Approach: A cylindrical water bath phantom a diameter 300 mm including two rods composed acrylic soft tissue-equivalent material was scanned using clinical computed tomography (CT) scanner at four levels (CT index 20, 15, 10, 5 mGy). Phantom images were reconstructed FBP, DLIR, IR. The...
The bone suppression technique based on advanced image processing can suppress the conspicuity of bones chest radiographs, creating soft tissue images obtained by dual-energy subtraction technique. This study was performed to evaluate usefulness in image-guided radiation therapy. We demonstrated improved accuracy markerless motion tracking images. Chest fluoroscopic nine patients with lung nodules during respiration were using a flat-panel detector system (120 kV, 0.1 mAs/pulse, 5 fps)....
Two deep learning image reconstruction (DLIR) techniques from two different computed tomography (CT) vendors have recently been introduced into clinical practice.To characterize the noise properties of DLIR with training methods, using a phantom containing simple uniform and complex non-uniform region.A water-bath diameter 300 mm was used as base phantom. A textured 128 mm, which made materials, one equivalent to water other being 12 mg/ml diluted iodine, irregularly mixed create texture...
Abstract This study investigates the relationship between contrast‐to‐noise ratio (CNR) and size‐specific dose estimate (SSDE) in computed tomography (CT) depending on patient size. In addition, to auto exposure control (AEC) techniques is examined. A tissue‐equivalent material having human‐liver energy dependence developed used evaluate these relationships. Three levels (constant CT index, constant SSDE, with AEC) are tested using four different phantom sizes (diameter: 15, 20, 25 30 cm)...
