Abstract Because of its excellent dose distribution, proton therapy is becoming increasingly popular in the medical application cancer treatment. A synchrotron-based facility was designed and constructed Shanghai. The synchrotron, beam delivery system, other technical systems were commissioned reached their expected performances. After a clinical trial 47 patients finished, obtained registration certificate from National Medical Products Administration. characteristics accelerator treatment...
Rumors flooding on rapidly-growing online social networks have geared much attention from many fronts. Individuals can transmit rumors via numerous channels since they be active multiple platforms. However, no systematic theoretical research of containing dynamics multiplex has been conducted yet. In this study, we propose a family strategies based the degree product each user networks. Then, develop heterogeneous edge-based compartmental theory to comprehend dynamics. The simulation results...
Background: Plastic scintillator detector (PSD) Exradin W1 has shown promising performance in small field dosimetry due to its water equivalence and sensitive volume. However, few studies reported capability measuring fields of conventional sizes. Therefore, the purpose this study is assess point dose both IMRT plans VMAT SRS plans. Methods: Forty-seven clinical (including 29 18 with PTV volume less than 8 cm 3 ) from our hospital were included study. Farmer-Type ionization chamber A19 used...
Purpose An adaptive planning target volume (PTV) margin strategy incorporating a volumetric tracking error assessment after each fraction is proposed for robotic stereotactic body radiation therapy (SBRT) liver treatments. Methods and materials A supervised machine learning algorithm employing retrospective data, which emulates dry‐run session prior to planning, used investigate if motion errors are <2 mm, consequently, margins can be reduced. of data collected during the beginning...
To compare the accuracy, advantages and disadvantages of automatic registration methods at different anatomical-sites for thoracic image-guided radiation therapy (IGRT). The Varian-IX IGRT system was used to perform a manual images collected on first fraction 60 patients with lung cancer (42 cases central location 18 peripheral). registered were as reference images. Offline performed computed tomography-CBCT using four methods: whole image registration, ipsilateral soft tissue tumor...
κ-Carrageenan was hydrolyzed with mild hydrochloric acid and separated into a series of oligosaccharides, the sequences structures which were investigated by double-quantum filtered correlation spectroscopy (DQF-COSY), total (TOCSY), heteronuclear multiple-quantum coherence (HMQC), multiple-bond (HMBC) techniques, respectively. The chemical conformations individual sugar residues identified, as well sequential connectivity oligosaccharides. interresidue nuclear Overhauser effects...
Abstract Background An analytical tool is empirically validated and used to assess the delivered dose liver lesions accounting for different types of errors in robotic radiosurgery treatment. Material methods A proposed estimate target doses taking into account translation, rotation, deformation a target. Translational are modeled as spatial convolution planned with probability distribution function derived from treatment data. Rotations by rotating volume about imaging isocenter. Target...
Abstract Purpose Trigeminal neuralgia (TN) can be treated on the CyberKnife system using two different treatment delivery paths: general‐purpose full path corrects small rotations, while dedicated trigeminal improves dose fall‐off but does not allow rotational corrections. The study evaluates impact of uncorrected rotations brainstem and length CN5 (denoted as L eff ) covered by prescription dose. Methods materials A proposed model estimates delivered considering translational errors for TN...
In the second part of our presentations we discuss results diffraction experiments from nanodiamond-polymer composite gratings performed with slow neutrons, i.e., at wavelengths longer than a nanometer. One goal investigations is to develop flexible, handy, low cost neutron diffractive optical elements (gratings) which can be tailored serve as mirrors, two-port beamsplitters, multiport polarizing beamsplitters or even assembled form an interferometer. Basically three adjustable...
Objective To study the methods of matching kilovolt CBCT image with planning CT scan. Methods A total 121 scans were matched scan using a manual and four automatic match by observers in offline. In match, live contour was used as surrogate for registration. Four methods, including routine soft-tissue bone liver vertebral body performed registration sofeware. First, stability sofeware tested. Then, reproducibility same method evaluated comparing different observers' results. After...
In this paper, we calculated the numeric results of diffraction field in space X-ray (λ=4.5nm) Fresnel zone plate based on angular spectrum method, analyzed axial and radial distribution patterns plate. The Full Width at Half-Maximum (FWHM), Depth Of Focus (DOF) Strehl efficiency focus spot were studied. Discussed relationships between FPZ's design parameter properties. At condition λ=4.5nm outmost width <i>Wn</i>=50nm, size is proportional to width, increase slowly with number zones length;...
