基于深度學習的甲狀腺醫(yī)學影像輔助診斷技術研究

基于深度學習的甲狀腺醫(yī)學影像輔助診斷技術研究摘要：甲狀腺疾病是常見的內分泌疾病，其臨床診斷依賴于醫(yī)學影像技術。然而，傳統(tǒng)的醫(yī)學影像診斷方法存在著可靠性低、誤診率高等問題。深度學習技術以其優(yōu)秀的特征學習能力和預測準確性，被廣泛應用于各個領域。本文研究基于深度學習的甲狀腺醫(yī)學影像輔助診斷技術，提出了一種基于卷積神經(jīng)網(wǎng)絡（CNN）的醫(yī)學影像分類方法。在此基礎上，開發(fā)了一套甲狀腺醫(yī)學影像輔助診斷系統(tǒng)，并應用于真實的臨床情況中。實驗結果表明，該系統(tǒng)能夠有效地輔助醫(yī)生對甲狀腺疾病進行診斷，達到了相對較高的診斷準確率和分類精度，提高了診斷效率和醫(yī)療質量。本文的研究成果對進一步促進甲狀腺醫(yī)學影像的研究和發(fā)展具有一定的參考和借鑒意義。
