UMDF named professor Cai Xiaochuan gives talk on math algorithms for predicting cardiovascular and cerebrovascular health
澳大發展基金會冠名教授蔡小川談預測心腦血管健康的數學算法

The University of Macau (UM) today (22 April) held a University of Macau Development Foundation Named Professorship Lecture. Cai Xiaochuan, University of Macau Development Foundation Chair Professor of Applied Mathematics, who is also an associate dean of the Faculty of Science and Technology and the director of the Centre for Applied Mathematics, was the keynote speaker. He gave a lecture titled ‘Mathematical Algorithms and Clinical Tests for Predicting Cardiovascular and Cerebrovascular Health’. The talk attracted many UM faculty members and students.

During the lecture, Cai discussed the recent applications of supercomputers and computational biomechanics in precision medicine. According to him, the human body has about 100,000 kilometres of blood vessels, large and small, which are constantly supplying nutrients to all organs at a rate of about one second per cycle. As we age, the health of blood vessels declines. Haemodynamics can be used to analyse health problems related to blood flow, such as cardiovascular and cerebrovascular diseases, as well as hypertension, from a mathematical and physical perspective. In recent years, due to the development of supercomputers and computational mathematics, computer-aided diagnosis based on haemodynamics is becoming a new tool to provide patients with convenient and accurate diagnoses and predictions, and to provide analysis of the healthiness of subnormal individuals.

澳門大學今（22）日舉行“澳門大學發展基金會冠名教授講座＂，由澳大發展基金會應用數學講座教授、澳大科技學院副院長、應用數學研究中心主任蔡小川以“預測心腦血管健康的數學算法與臨床驗證”為題發表演說，探討超級計算機及計算生物力學在精準醫療上的應用。講座吸引了眾多澳大師生出席，氣氛熱烈。

澳大副校長馬許願致辭時表示，澳大去年年底推出了新系列“澳門大學發展基金會冠名教授講座”，以分享冠名教授的學術成就及經驗，並加強與澳大社群的交流和互動，營造良好的學術氛圍。主講者蔡小川先後於北京大學取得理學士學位、紐約大學科朗數學研究所獲得哲學博士學位，並在耶魯大學擔任博士後研究員。2020年初加入澳大，其研究領域包括大規模計算及計算生物力學。

講座上，數學家蔡小川探討了超級計算機及計算生物力學近年在精準醫療上的應用。他指出人體有大約10萬公里長的大小血管以每秒鐘一個週期的速度不停的為各個器官提供養分。隨著年齡的增長，血管的健康程度逐漸遞減。血流動力學可以從數學物理的角度分析與血流相關的一些健康問題，比如心腦血管疾病、高血壓等。近年由於超級計算機和計算數學的發展，基於血流體動力學的計算機輔助診斷正在成為一種新的工具，為患者提供既便捷且準確的診斷及預測，為亞健康者提供健康度的分析。

蔡小川研究這領域逾二十年，他指出常用於心腦血管疾病的醫療影像診斷技術諸如電腦掃描、磁力共振掃描、超聲波等，均有其局限；但新式的計算機輔助診斷技術運用超級計算機計算血流動力，發揮了預測功能，在臨床上能輔助醫者作出不具入侵性且更準確的診斷，也為病人提供健康預測。他認為這研究在理論及臨床層面上均有遼闊的發展空間。在問答及交流環節時，與會者對這課題深感興趣，踴躍發問，討論氣氛熱烈。
