We demonstrate three-dimensional track reconstruction of electrons in a low pressure (50 Torr) optical TPC consisting two glass GEMs with an ITO strip readout CF4 and CF4/Ar mixtures. The reconstructed tracks show variety event topologies, including short from photoelectrons induced by 55Fe 5.9 keV X-rays long gamma ray interactions beta decays. Algorithms for identification ridge detection are...

Spatial distribution of biological cells plays a key role in tissue engineering for reconstituting the cellular microenvironment, and recently, acoustofluidics are explored as viable tool controlling structures fabrication because its good biocompatibility, low-power consumption, automation capability, nature non-invasive, non-contact. Herein, reusable acoustofluidic device is developed using s...

Profile extrusion is a production technique to make polymer profiles and hollow tubes. At certain distance after the die exit extrudate guided into cooling chamber, where cooled extensively set part dimensions. Uniform in chamber required avoid warpage twisting of due differential shrinkage. The effect on shape residual stresses final product are numerically studied. Two different cases studied...

introduction: well type ionization chamber is a measuring device which is used to determine the activity of brachytherapy sources. the chamber has a cylindrical volume in which a cylindrical tube is mounted in the middle of the chamber. for the measurements, the brachytherapy sources are transferred to the middle of the tube. materials and methods: for designing the well type chamber, the measu...

Introduction: Multiple fields and presence of heterogeneities create complex dose distributions that need three dimensional dosimetry. In this work, we investigated MR-based MAGIC gel dosimetry as a three-dimensional dosimetry technique to measure the delivered dose to bladder and rectum in prostate radiation therapy. Materials and Methods: A heterogeneous slab phantom including bones was made....

today radiology and imaging are the only and main method to generate geometrical data from body. 3d model of the body will give us the best and reliable information for better understanding and diagnostic. on the other hand with development of cad/cam and rapid prototyping, the 3d printers were born to build 3d models without considering the geometry. today the 3d printers are able to makes a 3...

A 56-year-old man with symptomatic atrial fibrillation (AF) was referred to our arrhythmia center for pulmonary vein isolation by catheter ablation. The patient underwent routine transesophageal echocardiography (TEE) and cardiac magnetic resonance (MR) examination before the catheter ablation. The cardiac MR examination consisted of time-resolved (4-dimensional) contrast-enhanced MR angiog-rap...
