Synchronisation of Ultrasound Scanners, Synchronisation of External Equipment

Ultrasound research may require synchronisation of ultrasound machine and other equipment. Telemed developed optional modules to equip ArtUs, SmartUs, MicrUs and ClarUs beamformers with such feature. Such optional modules (I/O modules) are available such modifications (see notes below) and should be ordered separately:

Signals description:

  • Ultrasound Line output - at falling edge system starts acquiring of ultrasound data from tissue for one ultrasound line
  • Ultrasound Frame output - at falling edge system starts acquiring of ultrasound data from tissue for one ultrasound frame
  • Ultrasound Line input - system starts acquiring of ultrasound data from tissue for one ultrasound line approximately in 20 us after rising edge of the signal
  • Ultrasound Frame input - system starts acquiring of ultrasound data from tissue for one ultrasound frame approximately in 20 us after rising edge of the signal
  • ScanStart output - system generate logic level "0" in Freeze mode and logic level "1" in scan mode
  • ScanStart input - system start scan (from new frame) when logic level "1" and stop scan when logic level "0"
