Ablation of solids by femtosecond lasers: ablation mechanism and ablation thresholds for metals and dielectrics [PDF]

Physics of Plasmas, 2001
The mechanism of ablation of solids by intense femtosecond laser pulses is described in an explicit analytical form. It is shown that at high intensities when the ionization of the target material is complete before the end of the pulse, the ablation mechanism is the same for both metals and dielectrics. The physics of this new ablation regime involves

Volumetric Quantitative Ablation Margins for Assessment of Ablation Completeness in Thermal Ablation of Liver Tumors [PDF]

Frontiers in Oncology, 2021
BackgroundIn thermal ablation of liver tumors, complete coverage of the tumor volume by the ablation volume with a sufficient ablation margin is the most important factor for treatment success. Evaluation of ablation completeness is commonly performed by visual inspection in 2D and is prone to inter-reader variability.

Ablation technologies

Surgery Open Science, 2022
Ablative therapies have recently emerged as an alternate to the gold-standard liver resection in treatment of malignant liver tumors. These modalities include radiofrequency ablation and microwave ablation which utilize thermocoagulative energy and microwave energy, respectively, to create a complete necrosis zone encircling the lesion. In this review,

Determination of lethal electric field threshold for pulsed field ablation in ex vivo perfused porcine and human hearts

Frontiers in Cardiovascular Medicine, 2023
IntroductionPulsed field ablation is an emerging modality for catheter-based cardiac ablation. The main mechanism of action is irreversible electroporation (IRE), a threshold-based phenomenon in which cells die after exposure to intense pulsed electric ...

Irreversible Electroporation Mediates Glioma Apoptosis via Upregulation of AP-1 and Bim: Transcriptome Evidence

Brain Sciences, 2022
The heat-sink effect and thermal damage of conventional thermal ablative technologies can be minimized by irreversible electroporation (IRE), which results in clear ablative boundaries and conservation of blood vessels, facilitating maximal safe surgical
