2026 biology talkshow:透視人體的宇宙-醫院放射性檢測技術

詳盡介紹醫療放射性檢測技術的科學原理與臨床應用，從倫琴發現 X 光的歷史契機談起，解釋游離輻射如何穿透人體成像。深入淺出地分析「透視三劍客」，包含利用電子撞擊產生的 X 光攝影、結合數學演算法重建三維結構的電腦斷層（CT），以及追蹤細胞代謝的核子醫學造影（PET/SPECT）。此外，也釐清核磁共振（MRI）與超音波並不含輻射的特性，並透過「香蕉等效劑量」的生動比喻來化解大眾對醫學輻射的恐懼。最後，展望 AI 科技與生物學的融合，強調這些精密工具是守護人類健康的微觀宇宙地圖。聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini)測驗網址 https://gemini.google.com/share/b704af514b1a Powered by Firstory Hosting
