Objective: To compare and analyze the clinical effects of ultrasound-guided percutaneous nephrolithotripsy and X-ray-guided percutaneous nephrolithotripsy in the treatment of complex renal calculi without hydronephrosis.Methods: Eighty patients with multi... see more

Objectives: To explore the curative effect of minimally invasive percutaneous plate osteosynthesis (MIPPO) technology combined with locking compression plates (LCP) guided by C-arm X-ray machine in the treatment of tibial metaphyseal fracture and its impa... see more

Beam hardening is a significant artifact that comes from the polychromatic nature of the X-ray source in computed tomography. It appears because the object tends to absorb more low-energy photons within the beam, which leads to a nonlinear relationship be... see more

Hafnium oxide (HfO2) thin films have been made by atomic vapor deposition (AVD) onto Si substrates under different growth temperature and oxygen flow. The effect of different growth conditions on the structure and optical characteristics of deposited HfO2... see more

Molecular dynamics is of fundamental interest in natural science research. The capability of investigating molecular dynamics is one of the various motivations for ultrafast optics. We present our investigation of photoionization and nuclear dynamics in m... see more

This work studied protective material consisting of several metal oxide composites (Pb3O4, WO3, SnO2, and Bi2O3)-natural rubber (NR) for X-ray and gamma-ray shielding. The composites were prepared through open milling and vulcanization processes and furth... see more

Penyakit virus corona 2019 (COVID-19) merupakan keadaan darurat kesehatan masyarakat secara global. Salah satu cara untuk dapat mendeteksi adanya COVID-19 adalah dengan memanfaatkan citra x-ray dada yang mengidentifikasi anomali pada area paru-paru. Namun... see more

The paper is devoted to the changes in the X-ray luminescence spectra of nanoscale Y2O3 ceramics, namely the radiation associated with a self-trapped exciton. Additional heat treatment (annealing) of ceramic samples leads to changes in the exciton band of... see more

In this work, the effect of proton irradiation on the change in the structure of silicon samples doped with platinum was studied. The samples were irradiated with protons at a dose of 9×1014 cm-2 with an energy of 600 keV and a current of 1÷1.5 µA. To det... see more
