The requirements to carrying out GDV-diagnostics

  • The room should be well ventilated. There shouldn’t be anyone in the room except the patient and the researcher. During GDV-diagnostics the patient should be relaxed and shouldn’t speak.
  • Before GDV-diagnostics damp hands should be dried with a dry cloth. Long nails should be cut short.
  • All metal objects (such as rings, bracelets, watch) should be removed from the patient’s hands.
  • A finger is positioned in the center of GDV-device so that the image shouldn’t move beyond the window frame (angle of slope is 10 – 30), and the finger should be perpendicular to the GDV-device front wall.
