A MRI cryostat (10) which contains a superconducting magnet operating in a bath of liquid helium (20) reduces the boil-off rate of helium by intercepting most of the heat in-leakage by means of a throttle cycle (TC) refrigerator operating at a low side temperature of about 90K. The main...

Purpose:To present the clinical setup and workflow of a robotic assistance system for image-guided interventions in a conventional magnetic ...
OPEN-LOOP AND CLOSED-LOOP IDENTIFICATION OF MODEL ERROR HARD BOUND IN FREQUENCY DOMAIN 来自 Semantic Scholar 喜欢 0 阅读量: 64 作者:M Kawata,Y Asano,A Sano 摘要: This paper presents a practical method for simultaneously identifying a nominal model and its model uncertainty bound in frequency ...
While initial reports of MRI-guided percutaneous biopsies date back into the late 1980s [3–6], the implementation of these tech- niques into clinical practice has mostly occurred in the last decade (Table 1). One of the reasons for this delay was the later introduction of open MRI systems...
