    摘要: An ablation system includes an ablation device configured to ablate a target, an imaging device, and a computing device. The imaging device is configured to capture images of a surgical site, in real time, including the target and the ablation device positioned relative to the target. The computing device includes a display configured to display a user interface. The user interface includes the images of the surgical site in real time and a simulation of ablation growth overlayed onto the images of the surgical site. Dimensions of the simulation of ablation growth may be based on expected ablation zone sizes for a fixed power setting at different energy application durations.

    摘要: A dielectric spacer for use during microwave ablation of tissue is disclosed. The dielectric spacer includes a housing having a predetermined thickness and a skin-contacting bottom surface. The housing is configured to be filled with a dielectric material having a predetermined dielectric permittivity. The housing is further configured to be placed on the tissue in proximity with at least one microwave antenna assembly, wherein the thickness and the dielectric permittivity are configured to shift a maximum voltage standing wave ratio of the at least one microwave antenna assembly.
