Key result
Microwave antennas demonstrated a less steep decrease in power deposition over distance compared to RF electrodes in saline phantoms, suggesting the capability to heat a larger volume.
Why the study?
Do microwave antennas produce different power deposition patterns compared to radio frequency electrodes in saline phantoms?

Phantom data favor microwave over RF for larger ablation volumes; hypothesis-generating, with in vivo cardiac validation required.
Do microwave antennas produce different power deposition patterns compared to radio frequency electrodes in saline phantoms?
Microwave antennas demonstrate a less steep decrease in power deposition over distance compared to RF, suggesting they may heat a larger volume and create larger lesions.
Lin et al. (1994) studied Cardiac arrhythmias. Microwave antennas vs. Radio frequency (RF) electrodes was evaluated on Power deposition patterns as a function of distance away from the electrode. Microwave antennas demonstrated a less steep decrease in power deposition over distance compared to RF electrodes in saline phantoms, suggesting the capability to heat a larger volume.
