Theoretical Modeling for Hepatic Microwave Ablation
Thermal tissue ablation is an interventional procedure increasingly being used for treatment of diverse medical conditions. Microwave ablation is emerging as an attractive modality for thermal therapy of large soft tissue targets in short periods of time, making it particularly suitable for ablation of hepatic and other tumors. Theoretical models of the ablation process are a powerful tool for ...
متن کاملAblation and Separation of Dermis via Ultra-short Pulsed Laser
Dermal tissue ablation and layer-separation with minimal thermal damage to the surrounding tissue via an ultra-short pulsed (USP) laser has been investigated. At first, a parametric study for wet tissue surface line ablation was investigated. The line features were measured by both microscope and scanning electron microscopy. The dermis ablation threshold and the incubation factor were determin...
متن کاملComparing the short and ultrashort pulsed laser ablation of LiF
Pulsed laser ablation of LiF was studied using both nanosecond (ns) and femtosecond (fs) pulses at 248 nm. Optical emission from electronically excited Li and F atoms in the plume of ejected material was investigated by wavelength, time and spatially resolved imaging methods. Careful analysis of images of species selected optical emission yielded estimates of the mean velocities of the Li+ ions...
متن کاملResidual Heat in Ultra-Short Pulsed Laser Ablation of Metals
In ultra-short pulsed laser ablation of metals, a considerable amount of the incident laser energy remains in the workpiece as residual heat. When using high repetition rates, this can cause severe damage due to heat accumulation effects. In this paper, the amount and the spatial distribution of the residual heat deposited by a spatially Gaussian-shaped laser pulse are investigated by means of ...
متن کاملDynamics of confined plumes during the short and ultra-short pulsed laser ablation of graphite
The optical emission from electronically excited C species in the ablation plume following the short (ns) and ultra-short (fs) UV pulsed laser ablation of graphite is studied. Wavelength, time and spatially resolved imaging of the plume, in background pressures of inert gases such as argon and helium, is performed. Analysis of images of optical emission from C+∗ ions and C2 radicals, yielded es...
