摘要To elevate tissue temperature to therapeutic level fast with optimal power deposition during hyperthermia treatment (HT) is a key treatment processing step. Traditionally we have treated the tumor volume, without considering possible existing thermally significant vessels, using a simple 1st-order temperature-based adaptive power scheme to determine optimal power deposition distributions. The difficulty of that approach when considering single large blood vessel, and proposed a novel fast scheme that could improve upon and substitute for the traditional temperature-based adaptive power scheme has been published by Huang etal [1]. The objectives of this study were to discuss the case with more than one thermally significant blood vessels (i.e. counter-current vessels) within a tumor. In this study, we presented the test of a novel three-coefficient-and two-SCV 5th-order temperature-based adaptive power scheme to resolve the induced large blood vessels problem in 3-D temperature distribution and introduced the parameter, SCV (Sentinel Convergence Value), to handle interior scheme shift. The 7th-order case will be discussed to resolve more convection involved blood vessels in the tumor. Results of the novel adaptive power scheme has
shown its robustness to fast approach optimal temperature distribution and power density distribution with high precision in the tumor volume when considering the existence of thermally significant blood vessel. Ultimately, we may be able to effectively calculate the absorbed power density distribution of 3-D biological tissues with a complicated vasculature [2] in the volume.
