The validity and reproducibility of measurements of the luminal diameter of the radial artery in man were investigated with Dermascan A, a 20 MHz ultrasound scanner. The luminal diameter of a reference object, a plastic tube, was measured with ultrasound to be 99.0% of stereomicroscopic measurements. By comparing the diameter of the reference object either filled with water or blood at 37 degrees C, the ultrasound velocity in human blood at 37 degrees C was calculated to be 1605 m/s.
