摘要：A method and apparatus of assessment of relative changes in the crosssectional area of a limb artery. The method includes applying to the artery an externalpressure, which causes the cross-sectional area of the artery to change between systoleand diastole much more than if the pressure is not applied, determining, over one or

more cardiac cycles, a baseline value for a parameter related to the cross-sectional areaof the artery, while the pressure is applied, applying a stimulus to the artery,determining, over one or more cardiac cycles, a stimulus-affected value for the

parameter related to the cross-sectional area of the artery, while the pressure is appliedand while the artery is in a dilated state affected by the stimulus and evaluating theartery based on a comparison of the determined stimulus-affected and baseline values,the baseline value is determined while the artery is substantially not affected by thestimulus.
