Abstract | Featured are a device with localized sensitivity to magnetic resonance signals, an imaging system using such a device and MRI methods for performing internal MRI or MRI Endoscopy. Such an MRI method includes introducing an MRI antenna or probe into the specimen to be imaged, the antenna being configured in accordance with the devices described herein, so that the spatial coordinate frame of imaging is inherently locked or defined with respect to the introduced antenna thereby providing imaging of the specimen from the point of view of the antenna. Further such imaging is conducted so that the MRI signal is confined substantially to a volume with respect to a particular region of the antenna or probe.
L'invention concerne un dispositif présentant une sensibilité localisée par rapport à des signaux de résonance magnétique, un système d'imagerie faisant appel à un tel dispositif et des procédés IRM permettant de réaliser une endoscopie IRM ou une IRM interne. Un tel procédé IRM consiste à introduire une antenne ou une sonde IRM dans l'échantillon à imager, l'antenne étant conçue pour s'adapter aux dispositifs de l'invention, de sorte que la trame de coordonnées spatiales d'imagerie est verrouillée ou définie de façon inhérente par rapport à l'antenne introduite, ce qui permet d'obtenir une imagerie de l'échantillon du point de vue de l'antenne. En outre, une telle imagerie s'effectue de sorte que le signal IRM est sensiblement confiné à un volume associé à une zone particulière de l'antenne ou de la sonde. |
