摘要： Disclosed herein are embodiments of segmented metallic guidewires that are suitable for MRI catheterization. Disclosed guidewires comprise a plurality of short conductive metallic segments that individually are short enough such that they do not resonate during MRI. The conductive segments are electrically insulated from each other and mechanically coupled together end-to-end via connectors, such as stiffness matched connectors, to provide a sufficiently long, strong, and flexible guidewire for catheterization that is non-resonant during MRI.

摘要： 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.

摘要： The use of standard coaxial cables for, e.g. connecting optional receive MR coils to MR-scanners has the problem that parasitic cable resonances may occur, which may cause RF burns to a patient. According to the present invention, the cable is divided into a huge number of small pieces. Each conductor in the small pieces is connected to the respective conductor in another small piece via a series capacitor. Due to this, e.g. at MR frequency, the cable according to the present invention is completely off resonant, such that no parasitic resonance may occur.

摘要： The invention provides for a magnetic resonance imaging system (100, 300) for acquiring magnetic resonance data (142) from a subject (118) within an imaging zone (108). The magnetic resonance imaging system comprises a magnetic resonance imaging antenna (113, 113′) comprising multiple loop antenna elements (114, 114′) with multiple infrared thermometry sensors (115, 115′). The magnetic resonance imaging antenna is configured for being positioned adjacent to an external surface (119) of the subject and at least a portion of the multiple infrared thermometry sensors are directed towards the external surface. The magnetic resonance imaging system further comprises a memory (134, 136) containing machine executable instructions (150, 152) and pulse sequence instructions (140). The machine executable instructions causes a processor controlling the system to: acquire (200) the magnetic resonance data by controlling the magnetic resonance imaging system with the pulse sequence instructions; repeatedly (202) measure at least one surface temperature (146) of the subject with the multiple infrared thermometry sensors during acquisition of the magnetic resonance data; and perform (204) a predefined action if the at least one surface temperature is above a predefined temperature.
