基于深度卷積神經(jīng)網(wǎng)絡(luò)的食管癌術(shù)前影像診斷關(guān)鍵問題研究
發(fā)布時(shí)間:2021-03-11 18:13
食管癌是八大常見惡性腫瘤之一,其發(fā)病率和死亡率居高不下。大多數(shù)患者在確診時(shí)已是局部進(jìn)展期或晚期,錯(cuò)失了治療最佳期,預(yù)后效果極差。影響食管癌預(yù)后的因素包括臨床分期、淋巴結(jié)狀態(tài)、病理類型等,早期診斷且個(gè)性化的治療方案、合理控制食管癌的發(fā)病危險(xiǎn)因素能有效改善食管癌患者的預(yù)后狀況。因此,對(duì)食管癌的早期診斷與治療變得十分重要。近年來(lái),以深度學(xué)習(xí)為主要代表的機(jī)器學(xué)習(xí)技術(shù)發(fā)展勢(shì)頭強(qiáng)勁,尤其是在自然語(yǔ)言處理、目標(biāo)識(shí)別、圖像處理等方面取得了良好的成果。醫(yī)學(xué)影像作為一種特殊的圖像,深度學(xué)習(xí)技術(shù)為醫(yī)學(xué)圖像數(shù)據(jù)的挖掘帶來(lái)了新的希望。尤其是在疾病的鑒別、診斷、檢出以及預(yù)測(cè)等方面大顯身手,在輔助臨床決策上帶來(lái)重要參考。新技術(shù)的出現(xiàn),為食管癌臨床診斷帶來(lái)了新契機(jī)。本文總結(jié)了深度學(xué)習(xí)近年在醫(yī)學(xué)影像方面的研究進(jìn)展,以及食管癌術(shù)前分期、淋巴結(jié)轉(zhuǎn)移狀態(tài)在臨床問題上面臨的挑戰(zhàn)與技術(shù)難題,將深度學(xué)習(xí)技術(shù)引入到食管癌術(shù)前影像診斷上,并展開研究。主要研究?jī)?nèi)容和創(chuàng)新點(diǎn)如下:1.針對(duì)食管癌臨床影像診斷過程中,部分必要影像圖像不完備的情況,本文提出了利用生成式對(duì)抗網(wǎng)絡(luò)從患者的平掃CT影像中生成對(duì)應(yīng)的對(duì)比增強(qiáng)CT影像,并改進(jìn)網(wǎng)絡(luò)引入感知特...
