International Journal of Medical Physics, Clinical Engineering and Radiation Oncology 2013年第1期2卷 15-18页

作者： Mutian Zhang sicong Li Hua Deng Sumin zhou Department of Radiation Oncology University of Nebraska Medical Center Omaha USA

Purpose: The objective of this study is to investigate the properties of I’mRT MatriXX device in electron beams, and to validate MatriXX in electron dosimetry and quality assurance (QA). Methods: The measurements were conducted using MatriXX in electron and photon beams from Siemens linacs. The MatriXX was placed horizontally on the linac tabletop. Solid Water layers were used for buildup. For all the measurements, the linac gantry angle was 0?, and the source-to-surface distance was100 cmfrom the Solid Water surface. The electron cone factors, cutout factors, and beam profiles were measured and compared with thimble ionization chamber results. Results: The effective water equivalent depth of MatriXX measurement point is larger than4 mm. When measuring at the respective depths of maximum dose, MatriXX has different responses to different beam energies. The cone factors measured by MatriXX are nearly identical or close to those derived by ionization chambers. Beam profiles (flatness and symmetry) can be easily determined using MatriXX and are comparable to water tank results. The planar dose map of electron cutout blocks can be visually observed, and the cutout factors can be conveniently measured. Conclusions: The MatriXX needs separate dose calibration factors for electron and photon beams. MatriXX can be used to measure electron cutout factors and beam profiles, thus has the potentials in electron beam dosimetry and routine linac and patient-specific QA tests.

International Journal of Medical Physics, Clinical Engineering and Radiation Oncology 2018年第1期7卷 100-114页

作者： Qiyong Fan Sumin zhou Yu Lei sicong Li Mutian Zhang Department of Radiation Oncology University of Nebraska Medical Center Omaha NE USA Summa Health Cancer Institute Akron OH USA

Purpose: With usually a millimeter-level PTV margin, stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) pose a stringent requirement on the isocentricity of the Linac. This requirement is partly fulfilled by routine isocenter quality assurance (QA) test to verify the size and location of the isocenter. The current common QA methods such as spoke shot were developed before SBRT/SRS became popular and when IGRT was largely absent and hence have their limitations. In this work, we describe an isocenter QA approach based on portal imaging to provide the community with a superior alternative. Methods: The proposed approach utilizes a BrainLab ball bearing (BB) phantom in conjunction with an electronic portal imaging devices (EPID) imager. The BB phantom was first aligned with a calibrated room laser system. Portal images were then acquired using 6 MV beam with a 2 × 2 cm2 open field and a 15 mm cone on a Varian TrueBeam STx machine. The gantry, collimator, and table were rotated separately at selected angles to acquire a series of portal images in order to determine the isocenter of each rotating system. The location and diameter of these isocenters were determined by calculating the relative displacement of either BB or open field edge between the acquired EPID images. The demonstration of the reproducibility and robustness of this EPID-based approach was carried out by repeating measurements 10 times independently for each rotating system and simulating clinical scenarios of asymmetric jaws and misalignment of BB phantom, respectively. Results: For our TrueBeam STx machine, the isocenter diameter derived from open-field EPID images was roughly 0.15 mm, 0.18 mm, 0.49 mm for the collimator, table, and gantry, respectively. For the collimator and gantry, images taken with the cone gave considerably smaller isocenter diameter. Results remained almost unchanged despite the presence of simulated BB misalignment and asymmetric jaws error, and betwe

In recent years, Apolygus htcorum has become the main pest of winter jujube. It sucks juice of young parts of winter jujube and causes falling of buds and flowers, leaf perforations, deformities and fall- off of fruits, leading to serious economic loss. Considering the occurrence characteristics and control problems, the distribution, occurrence regularity, damage characteristics and outbreak reasons of A. lucorum are overviewed and analyzed in this paper, and the pollution-free control measures are also put forward.

The key application technology for sex pheromone of Grapholitha molesta was studied from the aspects of different hanging heights and orientations, dif- ferent doses and types of traps through the tests on trapping quantity of G. molesta in fields. The results showed that the trapping effect was enhanced when the hanging height was increased, and the trapping effect was the best in west direction. The trapping effect was enhanced when the dosage was increased. When it was up to 6 lures, the trapping effect was the best with 38.75 head/trap; the next was 2 lures with 31.00 head/trap. All types of traps had trapping ability to G. mo- lesta, among which triangle trapper was the best, followed by self-made bottle trap. Their trapping effects were 138.75 and 100.25 head/trap, respectively.
