The panel shows the results of the analysis. The following data are displayed:

  • Calibration value [px/mm]
  • Mean IMT [mm] Intima Media Thickness. It is computed as an average value of the data present in the IMT chart.
  • Minimum IMT [mm] minimum value of Intima Media Thickness. It is computed on the data present in the IMT chart.
  • Maximum IMT [mm] maximum value of Intima Media Thickness. It is computed on the data present in the IMT chart.
  • Std. dev IMT [mm]: standard deviation of Intima Media Thickness. It is computed on the data present in the IMT chart.
  • Mean diameter [mm]: value of the average diameter. It is computed as an average value of the diameter data present in the Diameter chart.
  • Systolic diameter [mm]: value of the diameter in systole. It is computed as an average value of the systolic diameters present in the Diameter chart.
  • Diastolic diameter [mm]: value of the diameter in diastole. It is computed as an average value of the diastolic diameters present in the Diameter chart.
  • Blood pressure [mmHg]: diastolic pressure and systolic pressure.
  • Distension [mm]: stroke change in diameter.


  • Compliance [10-6·m2·kPa-1]: absolute change in lumen area for a given pressure change.


  • Distensibility [10-3· kPa-1]: relative change in lumen area during systole for a given pressure change.
  • Carotid Stiffness [m·s-1]: Stiffness value computed by Bramwell-Hill equation.
  • Young’s elastic modulus [kPa]:

    where:

De = External Diameter (between the media-adventitia interfaces) measured in diastole.

Di = Internal Diameter (between the lumen-intima interfaces) measured in diastole.

Ds = Systolic Diameter (external).

Dd = Diastolic Diameter (external), Dd = De

WCSA = Wall Cross Section Area      



ΔA = Stroke change in lumen area.

Ad = Diastolic Area.

Ps = Systolic Pressure.

Pd = Diastolic Pressure.

ΔP = Ps - Pd

ρ = Blood density: is assumed to be constant and equal to 1.06 g/cm3.
