Isbeddellada Qiimaha Magnet Dhulka Naadirka ah (250318)

Suuqa Spot ee Shiinaha - Qalabka Magnet-ka Dhulka Naadirka ah Oraahda Maalinlaha ah, Kaliya tixraac!

Sawirka Suuqgeynta

Pr-Nd Alloy

• Kala duwanaanshaha hadda: 543,000 - 547,000
• Isbeddelka Qiimaha: Deggan oo leh isbedbedel cidhiidhi ah

Dy-Fe Alloy

• Kala duwanaanshaha hadda: 1,630,000 - 1,650,000
• Isbeddelka QiimahaBaahida adag waxay taageertaa kor u kaca

Magnets-gacanta sare ee MRI: Saxnaanta & Hal-abuurka (598 chars)
Sawir-qaadayaasha casriga ah ee MRI waxay ku tiirsan yihiin niobium-titanium (NbTi) gariiradaha kondhomka sare leh ee lagu qaboojiyey helium dareere ah si ay u dhaliyaan beero 1.5-7T ah. Horumarka muhiimka ah:

• Midnimada goobtaGariiradaha shimming ee firfircoon ayaa sax ah ≤0.5ppm weecsanaan iyadoo la adeegsanayo khariidaynta waqtiga-dhabta ah ee B₀ (TR=2ms)
• Maareynta Quench: Qalabka gargaarka cadaadiska marxaladaha badan ayaa kala firdhiya tamarta 15MJ ee 0.3s inta lagu jiro gariiradda
• Cryogenics: cryocoolers-wareeg xiran ayaa ilaaliya 4.2K oo leh <10⁻⁶ W/㎡ dareeraha kulaylka

Halbeegyada waxqabadka:

• Nb₃Sn gariiradda: Gaaro 21T @ 15K (Brookhaven Lab 2024), awood MRI-goob sare
• Nidaamyada eber-karka: Ku kaydi 1500L helium muddo 10+ sano ah iyada oo loo marayo qaboojiyaha magnetic (teknoolojiyada ka soo jeeda NASA)
• Sawir-qaadista AI-ku-wadatoBarashada qoto dheer waxay dib u dhistaa 0.5mm切片图像 laga bilaabo 50% xogta cayriin (缩短扫描时间42%)

Kiis warshadeed: Nidaamka Siemens '7T Terra wuxuu hoos u dhigayaa qaylada codka ilaa 85dB (vs. 110dB常规MRI) iyada oo la joojinayo gariirka firfircoon, kor u qaadaya raaxada bukaanka.
