RF COIL OF MAGNETIC RESONANCE IMAGING

摘要

The objective of this is to comprise a frequency controlling part which controls oscillating frequency by controlling a pin diode as trigger pulse. The coil is characterized by including: a RF amplifying part(4) which inputs RF signal to a RF coil(5) by predetermined level through a computer(1), a searching processor(2) and a modem(3) ;a trigger pulse generator(11) which inputs to the RF coil by generating trigger pulse according to control signal outputed from the searching processor ;a pre-amplifying part(6) which inputs the high frequency wave received from the RF coil after amplifying by the predetermined level for making image by converting to the image signal from the computer through the modem(3), the searching processor(2). The effect is to gain clear image signal with no noise.
