| 摘要 |
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to devices for magnetic resonance. Device contains electric device or component, which includes printed circuit board, and radiofrequency shield, made with possibility of shielding electric device or component, with radiofrequency shield including earth bus of printed circuit board. Device is placed in opening of magnetic-resonance scanner in radiofrequency (B) field. Earth bus of printed circuit board includes electro-conductive sheet or layer, which has openings, suppressing vibration of earth bus, induced due to changing in time gradient of magnetic field. Magnetic-resonance system contains magnetic-resonance scanner, including basic magnet, winding for creation of magnetic field gradient and one or more radiofrequency coils for production of radiofrequency (B) field in studied area. Device is placed in opening of magnetic-resonance scanner.EFFECT: application of invention makes it possible to improve efficiency of MR-compatible electric device work due to reduction of vibration, caused by radiofrequency field.14 cl, 11 dwg |
