Title:
HIGH-FREQUENCY COIL AND MAGNETIC RESONANCE IMAGING DEVICE
Document Type and Number:
Japanese Patent JP3853282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high-frequency coil that improves the impedance of a blocking circuit, restrains the calorific value and reduces an irradiation output, and a magnetic resonance imaging device.
SOLUTION: A coil element 11 and a coil element 12 forming a receiving coil section are connected by a capacitor 24 and a capacitor 34, and a resonance circuit 20 is formed in the vicinity of the capacitor 24 and a resonance circuit 30 is formed in the vicinity of the capacitor 34. Furthermore, recesses 11a and 12a are provided at the ends of the coil elements 11 and 12 to prevent an interference between the resonance circuit 20 and the resonance circuit 30.
