Medical Electronics

Our small signal measurement technology and precision control technology are employed in the development of sophisticated medical devices for examination, diagnosis and treatment, such as MRI, MEG, artificial organs.

MRI

Technical Problem

  • Fast recovery from excessive signal
  • Ultra low noise

Solution

  • Bias stabilizing circuit
  • 50 Ω Active input impedance
  • Ultra Low Noise (Lower than the 50 Ω thermal noise of input resistance)
    Noise Figure: Less than 0.8 dB (15 MHz to 63 MHz)
    0.9 dB (83 MHz, at 50 Ω source)
  • Wideband: 300 k~ 100 MHz, +0.5, -3 dB
  • Fast Overload Recovery Time: Less than 200 μs (100 μs typ.)
  • High Gain. 44 dB ± 1 dB (15M~ 83MHz, at 50 Ω)

MEG (Magnetoencep-halograph)

MEG using the SQUID Sensor (highly sensitive magnetic sensor)

FLL (Flux Locked Loop)

ASP (Analog Signal Processor)
