Awọn oofa ti o gaju ni MRI: Itọkasi & Innovation (awọn ẹya 598)
Awọn aṣayẹwo MRI ti ode oni gbarale niobium-titanium (NbTi) awọn coils superconducting tutu nipasẹ helium olomi lati ṣe ina awọn aaye 1.5-7T. Awọn ilọsiwaju to ṣe pataki:
- Oko isokan: Awọn coils shimming ti nṣiṣe lọwọ ṣe atunṣe awọn iyapa ≤0.5ppm ni lilo maapu B₀ gidi-gidi (TR=2ms)
- Iṣakoso pa: Awọn falifu iderun titẹ ọpọlọpọ-ipele npa agbara 15MJ kuro ni 0.3s lakoko ikuna okun.
- Cryogenics: Awọn cryocoolers gigun-pipade ṣetọju 4.2K pẹlu <10⁻⁶ W/㎡ jijo gbona
Awọn aṣepari iṣẹ:
- Nb₃Sn coils: Ṣe aṣeyọri 21T @ 15K (Brookhaven Lab 2024), ṣiṣe MRI aaye giga-giga
- Odo-boiloff awọn ọna šiše: Tọju helium 1500L fun ọdun 10+ nipasẹ refrigeration oofa (imọ-ẹrọ ti NASA)
- AI-ìṣó aworan: Ẹkọ ti o jinlẹ ṣe atunṣe 0.5mm切片图像 lati 50% data aise (缩短扫描时间42%)
Ọran ile-iṣẹ: Siemens '7T Terra system dinku ariwo ariwo si 85dB (vs. 110dB常规MRI) nipasẹ ifagile gbigbọn ti nṣiṣe lọwọ, mu itunu alaisan mu.
