Abstract:
Cancer is one of the most feared health problems today. Studies on cancer diagnosis and treatment are carried out intensively. In this study, a graphene-based antenna is proposed for cancer diagnosis and treatment with THz radiation therapy, which is a relatively new radiation technique. A graphene-based two-layer monopole antenna is designed for 1.65THz operation frequency. To change the bandwidth and radiation pattern without changing the operating frequency, a graphene ring is placed on the SiO2 substrate (2nd layer).Antenna performance is analyzed for reflection coefficient, realized gain,

Simultaneous measurements of THz wave and hard X-ray emission from thin and flat water flow when irradiated by double femtosecond laser pulses (800 nm, 35 fs/transform-limited, 0.5 kHz, delay times up to 15 ns) were carried out. THz wave measurements by time-domain spectroscopy and X-ray detection by Geiger counters were performed at the transmission and the reflection sides of the flow.

Harmonic generation is an attractive research field that finds a variety of application areas. However, harmonic generation within a medium of micron-scale interaction length limits the magnitude of nonlinear coupling and leads to poor harmonic generation efficiency. In this study, we present a constrained non-linear programming approach based on the Quasi-Newton Broyden–Fletcher–Goldfarb–Shanno (BFGS) algorithm to obtain high-fidelity harmonic generation in optical micro-resonators. Using this approach, one can achieve high-intensity harmonic generation in a simple Fabry–Perot type optical mi

Owing to enhancing the radiation at the plasma corona and increasing the radiation temperature at the ablation front, the high-Z dopant in plastic target can significantly increase the ablation velocity and the blow-off plasma velocity, leading to an increase in

Theoretical modeling of the lesion formation process during radio-frequency ablation of the myocardium is presented. The model is axisymmetric and consists of a catheter electrode coming in contact at right angle with the heart tissue. The electric power dissipated in the tissue is calculated and from it the temperature distribution and the resulting lesion are evaluated as a function of time. The cooling effect of the blood flow and the temperature dependence of the electrical conductivity are included in the model, making it non-linear.

Introduction: Bimodal electric tissue ablation (BETA) is a new method of ablation, which combines the process of electrolysis with radiofrequency ablation (RFA) to increase the size of tissue ablations. The cathode of the electrolytic circuit is connected to the radiofrequency (RF) electrode to increase the surrounding tissue hydration. This allows the RFA process to continue for a longer period of time and therefore produce larger ablations. Previous research has shown that BETA could produce larger ablations compared to standard RFA and that it did not produce any significant short or long-

Abstract:
Ever since the first report of laser action, it has been recognized that laser ablation (evaporation/volatilization) may provide a useful sampling mechanism for chemical analysis. In particular, laser ablation is rapidly gaining popularity as a method of sample introduction for mass spectrometry. Since its original description, numerous research papers and review articles have appeared on various aspects of laser mass spectrometry.1,2 While most laser ablation/mass spectrometry has been performed with fixed frequency lasers operating at relatively high intensities/fluences (≥108 W/cm2, ≥1 J/cm

Abstract:
Abstract Microwave ablation (MWA) cures cancer by inserting slender antennas into tumors and producing large amounts of heat to kill cancerous cells. A key challenge is the selective heating of cancer cells without damaging the surrounding tissue, which requires a control of heating power for appropriate temperature distribution. This study established a theoretical simulation model for the microwave ablation of a porcine liver by using a coaxial-slot antenna with 10 slots at high frequencies. The axisymmetric finite element method (FEM) with temperature dependent thermal and dielectric proper

Abstract:
Radio frequency catheter ablation (RFCA) of cardiac arrhythmia is commonly performed by navigating the catheter manually. Nevertheless, remote navigation tech- niques where catheter steering is performed using either a magnetic field or robotically are available. Clinical ex- perience with these techniques demonstrated that higher contact forces can be achieved with robotic compared to magnetic field navigation [1]. This translates into more effective ablation lesions, but if excessive contact force is applied it may lead to higher risk of cardiac perforation [2]. However, the robotic navigati

Abstract:
Ablations have become the gold clinical standard of drug resistant atrial fibrillation (AF). AF is projected to affect 50 million people by the year 20501. Today, two primary methods of ablation are used clinically: radio frequency and cryoablation. These ablation technologies are equally effective1 but still cause complications. A majority of these complications arise from the fact that both technologies require a thermal change in the tissue to cause cell death. Thermal change of the tissue while effective, can be subject to many different variables that may result in collateral damage. Thes

RF Ablation Efficacy Testing: Modern surgical techniques utilize radio frequency ablation tools in minimally invasive procedures around the world today. The safety and efficacy of these tools must be verified before being used in human trials. This verification is typically performed on bovine, ovine, or porcine tissues which simulate clinical use.

Review question / Objective: Does catheter ablation for scar-related monomorphic ventricular tachycardia improve outcomes (defined as any appropriate ICD therapy, appropriate ICD shocks, all-cause mortality, VT storm, cardiovascular mortality, cardiovascular hospitalizations, complications) in adult patients with ischemic or non-ischemic cardiomyopathy and implantable cardioverter-defibrillator? Condition being studied: Ventricular tachycardia in patients with structural heart disease is usually an arrhythmia using the myocardial scar as a substrate for reentry. It poses a risk of syncope and
