ന㧋ኼ〛 • TOPIC INSIGHT 澳大ᑓゆ • 2019 UMAGAZINE 20 23 Prof Mok is an associate professor in the Department of Electrical and Computer Engineering and a joint associate professor in the Faculty of Health Sciences. She is the first native of Macao to become a medical imaging scholar in Macao. At age 18, she left Macao to pursue higher education at Yang-Ming University in Taiwan. After graduation, she was admitted by Johns Hopkins University in the United States, a universally acclaimed institution in the fields of medicine and public health. She is also the first Macao native to obtain a doctoral degree at JHU. She was later recruited by the Chinese University of Hong Kong as a junior faculty member before returning to Macao to join UM in 2010. Two years later, in 2012, she founded Macao’s first Biomedical Imaging Laboratory. Nuclear Medicine Imaging In nuclear medicine, patients are given small amounts of radioisotope-labelled drugs either orally or by injection. The radioisotopes then circulate through the body and are absorbed specifically by target organs or tumours under examination. The isotopes undergo radioactive decays and emit gamma rays from within the body, which are captured by a gamma camera to create images. By reconstructing and analysing these images, doctors can assess organ functions, tumour location, disease progression and staging, and effectiveness of the treatment. Prof Mok says that organ movements, such as the beating of the heart or the inflation and exhalation of the lungs, can sometimes lead to artifacts, which can degrade the interpretations of imaging results. The research team currently focuses on the development of nuclear medical instrumentation, methods of medical image generation, and subsequent processing and analysis, with the aim of making medical images of the brain, heart, liver and other organs more accurate, in order to improve the medical diagnosis and treatment of cancers. ‘Take the brain for example. We can’t directly assess the brain functions from the physical examination,’ says Prof Mok. ‘There are a lot of diseases such as Parkinson’s disease and dementia that don’t have obvious symptoms before the onset of the diseases. So the best way to detect disease pre-emptively is to use non-invasive medical imaging techniques, and nuclear medicine has obvious advantages over other imaging technologies in this ⬃ᒔ⭑ᒴ⏲ᇤಾ㡕㣊۠ 㣊⤾␗☲ ᐑእǍҀ༏⏲ಾಾ㡕Քͭ ᐑእ䢬 澳㟑首Φॶॶ㟊ⅰ㕕ಾྕ Ӎಾ⡃ǎ ⬃ᐑእ1 ᢱ㢹㟘澳㟑台Ტ㡩ᒛ大ಾ ڌ ಾ䢬ₔᜪྭ ㆯⓇॺ㕕ಾ⦾ՊՍ⻖ 㦦৴̷ ㄿ全球ⅰ⟜२☺⠯ğ㣗ᓠ㕷 ᑒ大ಾᏽㅂ ژ 䢬ᒴつಾ㡕首ΦϚ⦨ 澳㟑ⅰ ژ ₔᜪǎଡ́ྭ ᕋॺ㩿 中ᐵ大ಾͭ ᐑ䢬2010ोᨢ澳㟑؝Մ 澳大䢬2012⒢澳㟑首個ḳ㕕ಾྕ Ӎ㬟ೡǎ ᘾಠ㕗ೀྗ ӏ ॺᘼ㕕ಾ〹ᑘᑚ㤘䢬⃚̿ ᕐ⼕᧘ഥᆖ۲ ᕘറ㕵ഥလⳚḳ䢨 ܒ Φ♖䢩ǎ㐛̬ ܒ Φ♖ᕐ֯ ॺ̿ 㭓˗ ܒ ⅰ㒲Φ䢬Ցḿ₠ လⅰ⑆♟ྦ 〹ᑘⅰ࣮ ᆖ⥁℧䢬˧ ֦ Ι㪍ഥ⛨̿ 㭓͞ૣ 䢬⼕ന㟑ⅰΙ 㪍ᵦ⇀ᏹ㢡 ݶ 成ྕ Ӎǎ㐜㐿㕳ཅ˧֯ ᖾ㐛̬ྕ Ӎ䢬ന೮ൄ 能ഊ࣮ ⅰ功 能Ǎ⥁℧ⅰΦ⟂Ǎम㕳␗ༀ ݶ ᕔ ܩ ㎠ ␎䢬˧˜くΎℼᐅᗈ⓺ǎ⬃ᐑእゐ䢬࣮ ␎ ػ 䢨ϟ࿖㊎ᆖ⣀㒲Ԭᤵ ݩ ᤵ䢩 ᕔᒿᕐ͝㕕ಾྕӍ֦έѦྕ䢬ྕ㦏〹 ᑘǎ 研॰㡴˷⾾研ᘼ㕕ಾӵ࣮ ⅰ㟘發Ǎ 㕕ಾྕ Ӎ成ⅰᑚᧈ ྭݶ ❼ⅰⴵύ֯ ᖾ䢬ㅐ㕕ಾྕ Ӎᕅ؝☃ᬞ䢬ᩔ۠ 大⤾Ǎ ࿖⦝Ǎ⢬⦝⓺૦個࣮ 䢬۠͞ ⅂⃛ ⅰ〹 ᑘ ݶ ℼǎ⬃ᐑእゐ䢺Ǘㄵゐ⤾㒲䢬 ᆒмᴮᧈ↽ഊ⤾㒲ⅰ功能䢬⡈ᗫ㕷 㑋⃛ Ǎ智⃛ ⓺˗റ⃚⃛ 發⃚ נ 㓃ᦒᕔ ᒛ㧧⃛ Ṷ䢬ᕍତⅰᗾᑚᧈ䢬ൄ ᒴ㤔Ϸ Մလⅰ㕕ಾྕ Ӎኡ∫䢬⡈ॺᢪᅞ˔䢬 ᘼ㕕ಾ۞Ր͒ྕ Ӎᇤ⻐Ցᕔᒛ㧧Ԗ ن ǎǘᢪૣ 䢬Ҏᫎ⦾လ⥁℧ᒿ䢬㕕ㄺ̿ 㐜ຯᕐೌ ኯၴ ⡃۩ᢩ 㣊ಞኡዝ䢬 ԯധᕔഥလᤲ ឱ〤ⅰ葡⭉☖᧘ഥ㭓 Յǎⁱᑜ⥁℧ᕐܻ ᏹྩ ૦葡⭉☖䢬۸⾾ ഊ˗ᢩ ຯⅰǗ̺ 㷞ǘ䢬ൄ 能ྲ ≷⥁℧ ⅰΦ⟂ ݶ म㕳␗ༀ䢬۠͞ ᕔᦒᕔᯂॺⅰ ㎠␎ǎ
