In this paper, we introduce a novel application of volume modeling techniques on laser Benign Prostatic Hyperplasia (BPH) therapy simulation. The core technique in our system is an algorithm for simulating the tissue vaporization process by laser heating. Different from classical volume CSG operations, our technique takes experimental data as the guidance to determine the vaporization amount so that only a specified amount of tissue is vaporized in each time. Our algorithm uses a predictor-corrector strategy. First, we apply the classical CSG algorithm on a tetrahedral grid based distance field to estimate the vaporized tissue amount. Then, a volume-correction phase is applied on the distance field. To improve the performance, we further propose optimization approaches for efficient implementation.
在本文中，我们介绍了体积建模技术在激光良性前列腺增生（BPH）治疗模拟中的新应用。我们系统中的核心技术是一种通过激光加热模拟组织汽化过程的算法。与经典的体积 CSG 操作不同，我们的技术以实验数据为指导来确定汽化量，从而使每次仅汽化指定量的组织。我们的算法使用预测校正策略。首先，我们在基于四面体网格的距离场中应用经典的 CSG 算法来估计汽化组织量。然后，在距离场上应用体积校正阶段。为了提高性能，我们进一步提出了有效的优化方法。
