Laser-induced thermotherapy (LITT) is a minimally invasive method causing tumor destruction due to heat ablation and coagulative effects. Computer simulations can play an important role to assist physicians with the planning and monitoring of the treatment. Our recent study with ex-vivo porcine livers has shown that the vaporization of the water in the tissue must be taken into account when modeling LITT. We extend the model used for simulating LITT to account for vaporization using two different approaches. Results obtained with these new models are then compared with the measurements from the original study.

肝组织激光诱导热疗过程中气化的数学模型

激光诱导热疗法（LITT）是一种微创方法，由于热消融和凝血作用而导致肿瘤破坏。计算机模拟可以在协助医师计划和监测治疗方面发挥重要作用。我们最近对离体猪肝脏的研究表明，在对LITT建模时必须考虑组织中水的汽化。我们使用两种不同的方法扩展了用于模拟LITT的模型，以解决汽化问题。然后将这些新模型获得的结果与原始研究的测量结果进行比较。
