Model-based assessment of dynamic arterial blood volume flow from ultrasound measurements

Xv,m,b being the parameter value for the volunteer v, in measurement m at heartbeat b, Xv;m the average parameter for measurement m of volunteer v, and, bv,m and m being the number of heart beats of the measurement m for the volunteer v and the total number of measurements, respectively. The inter-registration variability rm that evaluates the variability between the measurements of the volunteer can be written as:
