Evaluation of the influence of probe pressure on the B-mode ultrasound measurement of arterial diameter.

This paper deals with the influence of the echographic probe pressure on the measurement of arterial diameter. It is common sense that arterial diameter measurements are affected by the pressure exerted on the B-mode ultrasound probe but we found no report in the current literature analyzing and quantifying this effect. We demonstrated this influence by the analysis of arterial images obtained with a conventional B-mode ultrasound system while monitoring the pressure exerted on the probe with a force sensor.
