Safety of strong, static magnetic fields

Autor: J F, Schenck

Publikováno v: Journal of magnetic resonance imaging : JMRI. 12(1)

Issues associated with the exposure of patients to strong, static magnetic fields during magnetic resonance imaging (MRI) are reviewed and discussed. The history of human exposure to magnetic fields is reviewed, and the contradictory nature of the li

MR safety at high magnetic fields

Autor: J F, Schenck

Publikováno v: Magnetic resonance imaging clinics of North America. 6(4)

MR imaging requires the exposure of human patients to magnetic fields that are much more intense than ever occur naturally. Under most circumstances, however, these fields do not appear to pose a health or safety risk even at levels well above those

Safety Issues in the MR Environment

Autor: J. F. Schenck

Publikováno v: Interventional Magnetic Resonance Imaging ISBN: 9783642643293

Although precise data are difficult to obtain, it is worthwhile to attempt to quantify the safety experience so far obtained with MRI. Using market research data it can be inferred that more than 100 000 000 diagnostic MR studies have been performed

Experience with MR-guided therapy

Autor: K G, Vosburgh, J F, Schenck

Publikováno v: Studies in health technology and informatics. 50

The use of magnetic resonance imaging (MRI) for the real time guidance of surgical procedures is now undergoing clinical trials. Among the many procedures explored, open craniotomy neurosurgery appears to be among the most promising. Over 50 such cas

MRI-guided noninvasive ultrasound surgery

Autor: K, Hynynen, A, Darkazanli, E, Unger, J F, Schenck

Publikováno v: Medical physics. 20(1)

In this study, the feasibility of using magnetic resonance imaging (MRI) to detect tissue necrosis induced by focussed ultrasound beams was investigated. It was shown that lesions produced in dog's thigh muscle in vivo were clearly visible in T2-weig

RESISTANCE IN THE MIXED STATE OF TYPE‐II SUPERCONDUCTORS

Autor: J. F. Schenck, R. W. Shaw, J. S. Willis

Publikováno v: Applied Physics Letters. 10:101-103

A mechanism is proposed for pinning of fluxoids by spatial inhomogeneities in the Ginzburg‐Landau kappa parameter of a material. This is applied to resistive data from Tl–Pb and Pb–In alloys.
