Introduction：

肝癌作為一種嚴(yán)重的惡性腫瘤，不僅會(huì)給患者帶來(lái)身體上的不適，還會(huì)對(duì)生活、心理和經(jīng)濟(jì)帶來(lái)巨大的負(fù)擔(dān)。目前，雖然有很多種治療方法，但是隨著技術(shù)的不斷進(jìn)步，熱消融已成為治療肝癌的有效方法之一。在熱消融過(guò)程中，選擇合適的治療路徑對(duì)于治療的效果和安全性非常重要。因此，本文將研究CT引導(dǎo)肝腫瘤熱消融治療手術(shù)路徑規(guī)劃的方法，并開(kāi)發(fā)一套系統(tǒng)，以提高熱消融治療的效益。

MaterialsandMethods:

本研究從2015年至今，收集了多個(gè)臨床病例，采用CT技術(shù)將肝癌病變的位置、大小、形態(tài)等信息進(jìn)行了收集。并使用MATLAB等軟件進(jìn)行數(shù)據(jù)的處理及計(jì)算，建立起路徑規(guī)劃的數(shù)學(xué)模型。本文采用遺傳算法優(yōu)化求解路徑規(guī)劃問(wèn)題，根據(jù)患者的具體情況，自動(dòng)規(guī)劃出腫瘤消融的最佳路徑。同時(shí)，本系統(tǒng)也加入了實(shí)時(shí)監(jiān)控等功能，以提供更加安全的治療模式。

Results:

通過(guò)對(duì)多個(gè)臨床病例的路徑規(guī)劃模擬，我們發(fā)現(xiàn)本系統(tǒng)能夠有效地規(guī)劃熱消融治療路徑，并能夠在短時(shí)間內(nèi)實(shí)現(xiàn)對(duì)肝癌的消融，同時(shí)收到了很好的治療效果。同時(shí)，本系統(tǒng)的規(guī)劃路徑也減少了手術(shù)過(guò)程中的風(fēng)險(xiǎn)，增強(qiáng)了手術(shù)的安全性。

Discussion:

本文使用遺傳算法建立了路徑規(guī)劃模型，能夠自動(dòng)計(jì)算出更合適的治療路徑，因此，在臨床應(yīng)用過(guò)程中能夠減少人員操作的失誤，提高治療的效率、安全性和準(zhǔn)確性。與傳統(tǒng)的手工計(jì)算方式相比，本系統(tǒng)無(wú)論是在效率還是準(zhǔn)確度方面都有了很大的提高。此外，在今后的研究中，我們會(huì)加入更多的數(shù)據(jù)，以進(jìn)一步完善本系統(tǒng)。

Conclusion:

本文通過(guò)研究CT引導(dǎo)肝腫瘤熱消融治療手術(shù)路徑規(guī)劃的方法，并以此次研究為基礎(chǔ)開(kāi)發(fā)設(shè)計(jì)一套系統(tǒng)，旨在提高肝癌熱消融治療的效率與安全性。該系統(tǒng)采用遺傳算法自動(dòng)規(guī)劃治療路徑，能夠在不損失治療效果的前提下減少手術(shù)的風(fēng)險(xiǎn)和損傷，提高治療效率和精度Introduction:
