Description
導電性流体により、組織を冷却、あるいは組織から熱を分散させることができる。流体の少なくとも一部分を沸騰させることにより、導電性流体は、交互にまたは併せて、組織および導電性流体の少なくとも一つから、熱を分散させる。
このとき、P = 熱に転換された合計RF電力 とする。
ΔT = (T- T∞) 組織のピーク温度 (T) と身体組織の標準温度 (T∞) との温度差 (℃)。身体組織の標準温度は一般に37 ℃。また、
R =周辺組織の熱抵抗、温度差と熱流の比率(℃/ watt)
ρ = 熱くはなるが沸騰はしない生理食塩水の密度(約1.0 gm/cm3)
cρ = 生理食塩水の比熱(約4.1 watt-sec/gm-℃)、
Ql = 加熱された生理食塩水の流量(cm3/sec)、および
ΔT = 生理食塩水の温度の上昇。生理食塩水が電極に到達する前に体温にまで加熱され、生理食塩水のピーク温度が組織のピーク温度と同程度であると仮定すると、これは上記の伝導の計算で得られたΔT と同じになる。
Ql = [P ? ΔT/R]/ρcpΔT ・・・・・(2)
となる。
Qb = 沸騰する生理食塩水の流量(cm3/sec)、および
hv = 生理食塩水の気化熱(約2,000 watt-sec/gm)とする。
ρ = 熱くはなるが沸騰はしない生理食塩水の密度(約1.0 gm/cm3)、
cρ = 生理食塩水の比熱(約4.1 watt-sec/gm-℃)、
V = 治療される組織の容積
ΔT = (T- T∞) 組織のピーク温度 (T) と身体組織の標準温度 (T∞) との温度差 (℃) 。 身体組織の標準温度は一般に37 ℃、また、
Δt = (t - t∞) ピーク温度(T)に到達するのにかかる時間と、身体組織の標準温度(T∞)(℃) に到達するのにかかる時間との差。
