Analytical Model Based on a Cylindrical Geometry to Study RF Ablation with Needle-Like Internally Cooled Electrode

López Molina, Juan Antonio; Rivera Ortun, María José; Berjano Zanón, Enrique (Hindawi Publishing Corporation, 2012)

Radiofrequency (RF) ablation with internally cooled needle-like electrodes is widely used in medical techniques such as tumor ablation. The device consists of a metallic electrode with an internal liquid cooling system ...
How coagulation zone size is underestimated in computer modeling of RF ablation by ignoring the cooling phase just after RF power is switched off

Irastorza, Ramiro Miguel; Trujillo Guillen, Macarena; Berjano, Enrique (John Wiley & Sons, 2017)

[EN] All the numerical models developed for radiofrequency ablation so far have ignored the possible effect of the cooling phase (just after radiofrequency power is switched off) on the dimensions of the coagulation zone. ...
How large is the periablational zone after radiofrequency and microwave ablation? Computer-based comparative study of two currently used clinical devices

Trujillo Guillen, Macarena; Prakash, Punit; Faridi, Pegah; Radosevic, Aleksandar; Curto, Sergio; Burdio, Fernando; Berjano, Enrique (Taylor & Francis, 2020-01-01)

[EN] Purpose To compare the size of the coagulation (CZ) and periablational (PZ) zones created with two commercially available devices in clinical use for radiofrequency (RFA) and microwave ablation (MWA), respectively. ...
Two-compartment mathematical modeling in RF tumor ablation: New insight when irreversible changes in electrical conductivity are considered

Castro-López, Dora Luz; Trujillo Guillen, Macarena; Berjano, Enrique; Romero-Mendez, Ricardo (2020)

[EN] The objective was to explore variations of temperature distribution and coagulation zone size computed by a two-compartment radiofrequency ablation (RFA) model when including simultaneously reversible changes in the ...
