TDS-4 is a Doppler Flowmeter and Spectrum Analyzer dedicated for Transcranial and Peripheral Blood Flow Measurements.
    Three independent ultrasonic transducers help to use the unit in a wide range of clinical applications. The 2 MHz P.W. probe is dedicated to intracranial blood flow assessment.
    The common TDS applications include: screening for intracranial diseases, MCA stem stenosis and occlusion, carotid siphon stenosis distal vertebral stenosis, basilar stenosis, collateral flow, vasospasms.

  • 4 MHz and 8 MHz C.W. probes are the ideal for the diagnosis of peripheral circulation (neck and upper and lower extremities)
  • The directional Doppler audio output is available through the built-in or external stereo loudspeakers.
  • The real-time spectrum analysis based on the complex 128-points FFT
  • The microprocessor based system computes instantaneously resistive index RI and pulsatility index PI as well as mean and maximum velocities.

    Patient data, examination and measurements parameters annotation are set directly from the keyboard. The results of the examination are stored on the monitor and recorded on the built-in hard and floppy disk.
