摘要： Disclosed herein are a signal transmission/reception method for signal analysis in FMMD technology and an apparatus using the method. A signal transmission apparatus includes a signal generation unit for generating two sine wave signals having different frequencies in consideration of a voltage of an excitation coil included in a magnetic particle measurement sensor, a signal addition unit for generating an input signal for producing a magnetic field by electronically adding the two sine wave signals, a differential signal generation unit for generating a differential signal for the input signal to minimize transmission noise, and a signal transmission unit for amplifying voltages of the input signal and the differential signal and transmitting the amplified input signal and differential signal to the excitation coil so as to produce a magnetic field in the excitation coil and apply the magnetic field to a measurement target sample.

摘要： Disclosed herein are a method for modifying a magnetic field using magnetic nanoparticles and an apparatus therefor. The method for modifying a magnetic field includes applying current to a single solenoid coil or to two parallel solenoid coils, measuring a strength of a magnetic field generated by the current at a preset target location using a measurement sensor, and controlling the strength of the magnetic field based on a concentration of a magnetic nanoparticle sample mounted in the single solenoid coil or the two solenoid coils so that the strength of the magnetic field matches a preset target value.

摘要： Disclosed herein are a magnetic-field-generating coil system, an imaging system having the magnetic-field-generating coil system, and a method for operating the imaging system. The method for operating an imaging system includes generating multiple Linear Gradient Fields (LGFs) in respective axial directions by controlling coil currents, and acquiring MRI information or Magnetic Particle Imaging (MPI) information about an object while moving the multiple LGFs by varying the coil currents.
